Description: MICROORGANISMS FOR TREATMENT OR PREVENTION OF OBESITY AND DIABETES MELLITUS, AND PHARMACEUTICAL COMPOSITION CONTAINING THE SAME Technical Field The present invention relates to microorganisms for the treatment or the prevention of obesity or diabetes mellitus , which reduces an amount of monosaccharide or disaccharide which can be absorbed into human body by means of converting monosaccharides such as glucose, fructose, galactose et al . and disaccharides into polymeric materials which cannot be absorbed in the intestine, and relates to a pharmaceutical composition containing the said microorganisms. Background Art As is known, obesity has been reported as a chronic disease caused by a lot of factors of which origins have not yet been discovered clearly. Obesity has been known as an inducing factor of hypertension, diabetes mellitus, coronary heart disease, gall bladder disease, osteoarthritis, sleep apnea, respiratory disorder, endomerial, prostate, breast and colon cancer et al . According to the NIH Report (The Evidence Report: Clinical guideline on the identification, evaluation, and treatment of overweight and obesity in adults, 1999, NIH), about 97,000,000 Americans are overweight and obese, and the number of patients of type 2 diabetes mellitus which relates obese, reach about 15,700,000 people. Moreover, it is reported that about 200,000 people died of diseases associated with obesity in every year (Dan Ferber, Science, 283, pp 1424, 1999) . Diabetes mellitus is one of the most wide-spread chronic disease in the world which requires a considerable expense to the public as well as to the patients of diabetes mellitus and their family. Furthermore, there are several types of diabetes mellitus caused by various etiological factors and of which pathogenesis are different from each other. For example, genuine diabetes mellitus is characterized by high level of blood glucose and glycosuria, and is a kind of disorder of carbohydrate metabolism caused by improper creation of insulin or actions thereof. Non-Insulin-Dependent Diabetes Mellitus (NIDDM) , or the type II diabetes mellitus is a disease of adults who have insulin-resistance in a peripheral target tissue, despite of normal formation and action of insulin. Non-Insulin-Dependent Diabetes Mellitus (NIDDM) occurs on account of three important metabolic disorder, such as the insulin-resistance, the fucntional disorder of the insulin secretion stimulated by nutrients, and the overproduction of glucose in liver. Failure to treat NIDDM (control of blood glucose level), leads to death due to the disease of atherosclerosis, and in addition, may cause late complications of diabetes, such as retinopathy, nephropathy or neuropathy . Sulfonylurea and biguanidine compounds therapy as well as diet-exercise therapy are included in NIDDM therapy to control blood glucose level. Recently, therapeutic compounds such as metformin or acarbose may be employed to treat NIDDM. However, hyperglycemia of some of diabetes mellitus patients cannot be controlled properly through diet and/or exercise therapy or in spite of chemotherapy with such compounds. In case of these patients, exogenous insulin should be administered. Administration of insulin is very expensive and painful method to patients. Furthermore, this may cause various detrimental states and various complications for patients . For example, an insulin response (hypoglycemia) may be caused by miscalculating the insulin dosage, going without a meal and by irregular exercise, and may also be caused without particular reason. In addition, an allergy on local or whole body or immunological resistance to insulin, may be occurred by insulin injection. There are several ways to prevent of or to treat obesity and diabetes mellitus, such as diet-exercise therapy, a surgical operation or chemotherapy. Diet- exercise therapy is a method to take a low-calorie and low- fat diet and to take aerobic exercise, but it is recognized in general that this method is not successful to the public at large because it needs to be performed regularly. A surgery to remove body fat physically, has instant effects and however, has some limitations because of the risk of performing a surgical operation, non-continuous durability of the effect and the cost being very expensive. Pharmacotherapy with medicines which can reduce blood glucose level, inhibit absorption of glucose, strengthen the action of insulin or induce a decrease of appetite, is an most actively developed method currently in this field. The medicines developed until now for treatment and prevention of obesity and diabetes mellitus, make use of various physiological mechanisms. Some drugs which enhance the action of insulin, such as sulfonylurea, metformin, pioglitazone or thiazolidindione derivatives et al . , have been developed. Sulfonylurea has an effect of a stimulation of insulin-secretion from 3-cells in the pancreas, but may cause a side effect called hypoglycemia which lowers blood glucose level below the normal level. Metformin is used mainly on insulin-nondependent diabetes mellitus patients who are not recovered by diet or exercise therapy. This medicine inhibits the hepatic gluconeogenesis and enhances glucose disposal in muscle and adipose tissue. However, it has been known that this medicine has a side effect of nausea, vomiting and diarrhea. Pioglitazone developed by Takeda of Japan, enhances the action of insulin through increasing the susceptibility on cell of insulin (Kobayashi M. et al., Diabetes, 41(4), pp 476-483, 1992). Beta 3-adreno receptor inhibitor (BRL-35135) which is known as a medicine which stimulates the decomposition of body fat, decomposes body fat and convert them into heat by acting specifically on adipose cell and concurrently, lowers blood glucose level. The inhibitor of a pancreatic lipase (Orlistat produced by Roche of Swiss) which is known as a medicine inhibiting absorption of fat, reduces absorption of fat by inhibiting function of pancreatic lipase, however, it inhibits also absorption of fat-soluble vitamin and may cause breast cancer . Generally, the medicines which inhibit appetite, decrease appetite by acting on catecholamine in the brain. However, dexfenfluororamine and fenfluoroamine have side effects of neuro-toxicity, valvular heart disease. Also, sibutramine has side effects of increasing heart rate and blood pressure. α-Glucosidase inhibitor (Acarbose produced by Bayer of Germany), is known as medicines for glucose absorbing inhibitor. Acarbose is pseudo-monosaccharide which competitively inhibits the action of various -glucosidase existing in microvilli of the gastrointestinal tract. However, these may induce diarrhea in case that a large amount thereof was taken (W. Puls et al., Front. Horm. Res. 2, 235, 1998). Amylase inhibitor had been developed to prevent imbalance of metabolism originated from excessive uptake of nutrient, by means of inhibiting the action of amylase converting carbohydrates into oligosaccharides (Sanches- Monge R. et al .. Eur. J. Biochem. , 183, 0037-40, 1989). Taking of dietary fiber is the easiest method to obtain inhibitory effect of obesity by lowering glucose and/or fat amount absorbed in the intestine by means of diet with lots of vegetable fiber. However, this method has some problems that enormous facility and manpower are required for the production of dietary fiber and the productivity thereof is very low. Polymeric materials such as isomaltotriose, dextran and pullulan, inhibit the increase of blood glucose level originated from taking glucose. However, such materials have severe side effects also. For example, dextran may induce excessive bleeding by delaying a blood coagulation time. Among said various medicines, dietary fibers are recognized as the most useful medicine for prevention or treatment of obesity because it does not damage to human metabolism-balance and it is a natural substance. Microorganism dietary fiber is produced by microorganisms, such as Gluconobacter sp . , Agrobacterium sp . , Acetobacter xylinum, A . hansenii , A . pasteurianus , A . aceti, Rhizobium sp . , Alcaligenes sp . , Sarcina sp . , Streptococcus thermophilus , Lactococcus cremoris, Lactobacillus helveticus, Lactobacillus bulgaricus , Lactobacillus sake, Lactobacillus reuteri , Lactobacillus lactis, Lactobacillus delbrueckii subsp. , Lactobacillus helveticusglucose var. jugurti , Leuconostoc dextranicum, Bulgariscus sp . , Campestris sp . , Sphingomonas sp . Dietary fiber produced by these microorganisms is used as stabilizer, thickening agent, emulsifier, hygroscopic agent of various foods and raw materials of cosmetics and pharmaceuticals. Microorganism cellulose, xanthan, acetan, et al . , guar gum, locust bean gum, carrageenan, alginate, agar obtained from seaweed are commerciallized. Lactobacillus sp . strain is the major component of normal microbial flora in the intestine of human body. Its important role for the maintaining a healthy digestive organ and for the circumstance of the vagina, have been well known long ago[Bible, D. J., ASM News, 54:661-665, 1988; Reid G. and A. W. Bruce, In H Lappin-Scott (de.), Bacterial biofilms, Cambridge University Press, Cambridge, England, p. 274-281, 1995; Reid G. , A. W. Bruce, J. A. McGroarty, K. J. Cheng, and J. . Costerton, clin. Microbiol. Rev., 3:335- 344, 1990]. Generally, Lactobacillus strain inhabits in the digestive organ (L . acidophilus , L . intestinalis , L . johnsonii , L . reuteri et al . , ) , uscosa of the vagina ( . vanginals, L . gasseri ) , food (wine-L. hilgardii ) , lactobacillus beverage (L . kefir, L . kefiranofaciens) , cheese (L . casei) , vinegar (L . acetotolerance ) , the oral cavity (L . oris ) , yeast (L . sake, L . homohiochi ) , fruit juice (L . kunkeei , L . mail , L . suebicus ) , fermented sausages or fish (L . farciminis, L . aliment arious ) et al .. Many people take health complementary food containing Lactobacillus sp . strain in order to maintain healthy intestine and to prevent urogenital tract infection. Recently, the various probiotic activities of Lactobacillus , such as the control of immunity, the control of cholesterol level in blood, the prevention of cancer, the treatment of rheumatism, the alleviation of sensitivity on lactose or the effect for atopic dermatitis, in addition to the prevention of the diarrhea, constipation and urogenital tract infection, have been disclosed and concerns therefor are going to increase. According to U.S. Public Health Service Guideline, all of 262 Lactobacillus deposited in ATCC are classified as "Bio-safety Level 1" which stands for that there is no potential risk which has been known up to now, to cause the disease to human or animals. Among approximately 60 strains of Lactobacillus , there is no one poisonous to human body. Recently, the research for an extracellular dietary fiber produced by Lactobacillus advances are progressed actively. It has been reported that a process of producing dietary fiber in these strains are very complicated because a lot of genes are mediated in the said process, and that the amount of dietary fiber thus produced are very little (Int. J. Food Microbiol. , Mar 3 40:1-2, 87-92, 1998; Current Opinion in Microbiology, 2:598-603, 1999; Appl. Environ. Microbiol., Feb 64:2, 659-64, 1998; FEMS Microbiol. Rev. Apr 23:2 153-77, 1999; FEMS Microbiol. Rev. Sep 7:1-2, 113-30, 1990) . Also, various researches on the synthesis of cellulose by Acetobacter sp . which is well known as microorganism producing dietary fiber, have been performed (Aloni Y., cohen R., Benziman M. , Delmer D, J Biological chemistry, 171:6649-6655, 1989; Ascher M. , J. Bacteriology, 33:249-252, 1937; Benziman M., Burger-Rachamimv H., J. , Bacteriology, 84:625-630, 1962; Brown AM. Journal of Polymer science, 59:155-169, 1962; Brown AM, Gascoigne JA, Nature, 187:1010- 1012, 1960; Calvin JR, Planta DP, Benziman M. , Padan E, PANS USA, 79:5282-5286, 1982; Dehmer DP. Brown RM Jr., Cooper JB, Lin FC, Science, 230:82-825, 1985). Acetobacter is a strict aerobe but has characteristics of surviving and living under the condition of infinitesimal oxygen, and of being floated to seek for oxygen by means of synthesizing cellulose dietary fiber of itself under this condition of infinitesimal oxygen. According to the research regarding to the amount and rate of converting glucose into cellulose dietary fiber by Acetobacter (Brown et al.: Proc . Natl. Acad. Sci. USA, Vol73 (12), 4565-4569), Acetobacter converts glucose into cellulose at the speed of 400 amol/cell/hour . This rate is the equivalent rate that about 200g glucose can be converted into cellulose by 4 x 10 15 cells per an hour. It has been reported rarely that there is Acetobacter which can metabolizes saccharose. However, Acetobacter that can convert saccharose into glucose, exists in nature (PNAS, 9: ppl4-18). Presently, the FDA of the United States has approved Acetobacter xylinum as for synthesizing acetic acid and sorbose, and has classified it as generally safe microorganism (GRAS: Generally Recognized As Safe). As mentioned above, there have been various researches and efforts to develop the drugs for treatment or prevention of obesity and diabetes mellitus up to now, however, the results thereof were unsatisfactory. The various chemical substances mentioned above, have been developed for the drug of treatment for obesity and diabetes mellitus, but have several side effects. These drugs discharge body fat forcibly along with valuable proteins. Consequently, any one single drug of treatment or suppresses obesity and diabetes mellitus at the origin thereof does not exist yet. Disclosure of Invention Therefore, the object of the present invention is to provide microorganisms which can live within the intestine and can convert oligosaccharide prepared by the digestive enzymes into non-digestible polysaccharide, and thereby can reduce remarkably the amount of oligosaccharide can be absorbed into the intestine. The another object of the present invention is to provide a pharmaceutical composition which contains the said microorganisms in pharmaceutically effective amount, that would treat or prevent of obesity and diabetes mellitus by reducing, at the source, the amount of oligosaccharide which can be absorbed by the intestine of human body. The microorganisms which can be used as the active principle of the pharmaceutical composition of the present invention preferably fall within Acetoiiacter genus , Gluconobacter genus, Lactobacillus genus , and Acrobacterium genus which can live in the intestine and are not harmful to human body and can convert oligosaccharide into polysaccharide which cannot be absorbed into human body. Specifically, the following microorganisms can be used as the microorganisms of pharmaceutical composition of the present invention, such as Acetobacter xylinum, A . hansenii , A . pasteurianus , A. aceti, Lactococcus cremoris, Lactobacillus helveticus, L . bulgaricus , L . sake , L . reutari , L . lactis, the subspecies of L . delbrueckii , L . delbrueckii subsp . , and a variant form of L . helveticusglucose . Preferably, the microorganisms can be used as the active principle of the pharmaceutical composition of the present invention are Lactobacillus sp . BC-Y009 (KCTC0774BP) strain and Acetobacter sp . BC-Y058 (KCTC0773BP) strain. The pharmaceutical composition of the present invention may be administered in a form of tablet or capsule of pharmaceutical formulation which comprises exipients, pharmaceutically allowable vehicles and carri.er which are selected depending on the administration route. The pharmaceutical formulation of the present invention may further comprise supplemental active ingredients.

In addition, the pharmaceutical composition of the present invention may further comprise lubricants, moisturizer, emulsifier, suspension stabilizer, preservative, sweetener and flavor. The pharmaceutical composition of the present invention may be produced as an enteric coating formulation through various methods which have been known to public already, in order that the active ingredients of the pharmaceutical composition, i.e., microorganisms, can pass through the stomach without being damaged by gastric juice. Furthermore, microorganisms of the present invention may be administered in a form of capsule prepared by conventional process. For example, standard vehicles and lyophilized microorganisms of the present invention are mixed together and prepared to pellets and then, the pellets are filled into hard gelatin capsule. In addition, the microorganisms of the present invention and pharmaceutically allowable vehicles, for example, aqueous gum, cellulose, silicate or oil are mixed to produce a suspension or disperse and then, this suspension or dispersion may be filled into soft gelatin capsule. The pharmaceutical composition of the present invention may be prepared to an enteric coating tablet for oral administration. The term "the enteric coating" of this application includes all conventional pharmaceutically allowable coating that cannot be decomposed by gastric juice, however, in the small intestines, can be disintegrated sufficiently to release the microorganisms of the present invention rapidly. The enteric coating of the present invention is maintained for more than 2 hours in the synthetic gastric juice, such as HCl solution of pH 1 at the temperature of 36°C to 38°C and desirably, is decomposed within 0.5 hours in the synthetic intestinal juice, such as KH 2 P0 4 buffer solution of pH 6.8. The enteric coating of the present invention is coated on each tablet with the amount of about 16 to 30mg, desirably 16 to 25 mg, more desirably 16 to 20mg. The thickness of enteric coating of the present invention is 5 to lOOjum, desirably 20 to 80jum. The components of the enteric coating are selected appropriately from common polymeric materials which have been well known to public. The polymeric materials which may be employed for enteric coating of the present invention are enumerated and described in the flowing articles [The Theory and Practices of Industrial Pharmacy, 3rd Edition, 1986, pp. 365-373 by L. Lachman, Pharmazeutische Technologie, thie e, 1991, pp. 355- 359 by H. Sucker, Hagers Handbuch der Pharmazeutischen Praxis, 4th Edition, Vol. 7, pp. 739, 742, 766, and 778, (SpringerVerlag, 1971), and Remington's Pharmaceutical Sciences, 13th Edition, pp. 1689 and 1691 (Mack Publ . , Co., 1970)]. For example, cellulose ester derivative, cellulose ether, and copolymer of acryl and methyl aerylate or maleic acid or phthalic acid derivative may be employed in enteric coating of the present invention. The preferred enteric coating of the present invention are prepared from polymers of cellulose acetate phthals or trimellitate and methacrylic copolymer (for example, copolymer of more than 40% of methacryl acid and methacryl acid which contains hydroxyprophyl methylcellulose phthalate or derivatives from ester thereof). Endragit L 100-55 manufactured by Rohm GmbH of Germany may be used as a raw material for the enteric coating of the present invention. The cellulose acetate phthalate employed in the enteric coating of the present invention, has about 45 to 90 cP of viscosity, 17 to 26% of acetyl contents and 30 to 40% of phthalate contents. The cellulose acetate trimelitate used in the enteric coating, has about 15 to 21 cS of viscosity, 17 to 26% of acetyl contents, and 25 to 35% of trimelityl contents. The cellulose acetate trimelitate which is manufactured by the Eastman Kodak Company may be used as a material for the enteric coating of the present invention. Hydroxypropyl methylcellulose phthalate used in the enteric coating of the present invention has molecular weight of generally 20,000 to 130,000 dalton, desirably 80,000 to 100,000 dalton and has 5 to 10% of hydroxypropoxy contents, 18 to 24% of methoxy contents, and 21 to 35% of phthalyl contents. Cellulose acetate phthalate which is manufactured by the Eastman Kodak Company can be used as a material for the enteric coating of the present invention. Hydroxypropyl methylcellulose phthalate used in the enteric coating of the present invention is HP50 which is manufactured by the Shin-Etsu Chemical Co. Ltd., Japan. The HP50 has 6 to 10% of hydroxypropoxy contents, 20 to 24% of methoxy contents, 21 to 27% of propyl contents, and molecular weight is 84,000 dalton. Another material for enteric coating manufactured by the Shin-Etsu Chemical Co. Ltd., is HP55. HP55 can also be used as material of the enteric coating of the present invention. The HP55 has 5 to 9% of hydroxypropoxy contents, 18 to 22% of methoxy contents, 27 to 35% of phthalate contents, and molecular weight is 78,000 dalton. The enteric coating of the present invention is prepared by using a conventional method of spraying the enteric coating solution at the core. The solvents used in the process of the enteric coating are alcohol such as ethanol, ketone such as acetone, halogenated hydrocarbon such as dichloromethane, or the mixture thereof may be used. Softeners such as Di-n-butylphthalate and triacetin are added to the enteric coating solution in the ratio of 1 part coating material to about 0.05 or to about 0.3 part softner. The spraying process preferably be performed continuously and the amount of materials sprayed may be controlled depending on the condition of the coating process. Spraying pressure may be regulated variously and generally, desirable result can be obtained under the pressure of average 1 to 1.5 bar. The "Pharmaceutically effective dosage" of this specification means the minimum amount of the microorganisms of the present invention, which can reduce the amount of oligosaccharide absorbed into the body in the intestines of mammalian animals . The amount of microorganisms administered into a body with the pharmaceutical composition of the present invention may be adjusted depending on the administration method and the administration subject. The composition of the present invention may be administered once or more per day on the subject. The unit of administration amount means that it is separated physically and thus is suitable to the unit administration for the human subjects and all other mammalian animals. And each unit contains a pharmaceutically allowable carrier and the amount of the microorganisms of the present invention which are effective in therapy. In the oral administration unit of an adult patient, microorganisms of the present invention are contained desirably O.lg or more and composition of the present invention is 0.1 to lOg per one time administration, desirably 0.5 to 5g. The pharmaceutically effective dosage of microorganisms of the present invention is O.lg per 1 da . However, the administration amount is variable depends on the weight and the severity of obesity of the patient, the supplemental active ingredients included and the microorganisms used therein. In addition, it is possible to divide up the daily administration amount and to administer continuously, if needed. Therefore, range of the said administration amount does not limit the scope of the present invention in any way. The "composition" of the present invention means not only as medicinal products but also to serve as functional foods and health complementary foods . In case of taking the composition of the present invention periodically, microorganisms form colony within the intestine and interrupt absorption of oligosaccharide in the body competitively. Also, non-digestible fibers produced by microorganisms make a healthy condition for other useful microorganisms within the intestine and stimulate the intestinal activity. Consequently, the composition of the present invention functions to treat and prevent obesity and diabetes mellitus.

In addition, the present inventors have isolated and obtained novel microorganisms which can be used as an active principles of the pharmaceutical composition of the present invention. In order to isolate and obtain novel microorganisms which can satisfy the requirements to be used as an active principle of the pharmaceutical composition of the present invention, the present inventors have researched as follows. Samples of microorganisms collected from the glucose factory sewage and other locations were inoculated in MRS and BHS agar mediums containing cycloheximide, and then cultured. Colonies formed in agar medium were then inoculated into MRS and BHS liquid medium and incubated without shaking. Microorganisms that formed a matrix or a membrane shape on top layers of the medium were selected. Formed membranes were separated and tested for whether or not the separated membranes were decomposed by the intestinal digestive enzyme. The results determined whether non-digestible (or hardly digestible) high molecular-weight compounds were produced or not. Among the microorganisms, BC-Y009 and BC-Y058 were selected for their high productivity of extracellular polysaccharide (dietary fiber) . Upon observing the morphology of BC-Y009 and BC-Y058 and comparing with 16s rRNA's partial DNA sequences, it was confirmed that each showed high percentage of homology sequence when compared with Lactobacillus and Acetobacter. Based on the phenotype and 16s rRNA DNA sequence analysis, it was ascertained that BC-Y009 is a novel microorganism which falls within the Lactobaccilus genus and BC-Y058 as a novel microorganism of Acetobacter genus . Lactobacillus BC-Y009 and Acetobacter BC-Y058 of the present invention were administered into a mouse which was induced of obesity and diabetes mellitus. The blood glucose level of a subject mouse had been decreased approximately 70% after administration. According to these results, it was confirmed that microorganisms of the present invention has an effect in decreasing blood glucose level and thus it is effective for treating and preventing against diabetes mellitus. When microorganisms of the present invention, BC-Y009 and BC-Y058 were administered into a mouse induced with diabetes mellitus and obesity, the feed consumption rate increased 17 to 24% upon comparison with a control mouse. However, weight gain versus feed consumption amount was decreased. The result thus indicates that the microorganism composition of the present invention allows for humans to consume without worrying about obesity nor diabetes mellitus . In case of taking these microorganisms, blood lipid amount also is lower than that of control group, it was learned that the microorganisms of the present invention can control the occurence of diabetes mellitus, obesity and circulatory diseases (for example, arteriosclerosis, myocardial infarction) . Hereinafter, the present invention will be further explained with reference to the following examples. The examples are given only for illustration of the invention and are not intended to be limiting the scope of the present invention. Example 1. Selecting of microorganism which produces extracellular polysaccharide from samples In order to isolate microorganisms which produce dietary fibers, samples were collected from glucose factory sewage and other locations. 10G of the mixture thus collected were disrupted and suspended in 90ml of physiological saline solution( 0.85% NaCl). The said suspended samples were diluted to 10 "2 , 10 ~4 , and 10 "6 in physiological saline solution. These diluted samples then smeared on MRS agar medium containing 1 mg of cycloheximide per 100ml medium(l% Peptone, 1% beef extract, 0.5% yeast extract, 2% glucose, 0.1% Tween-80, 0.2% Citric Acid Ammonium, 0.5% Sodium Acetate, 0.01% MgS0 4 , 0.005% MnS0 4 , 0.2% Sodium Phosphate pH6.5) and on BSH agar medium(2% glucose, 0.5% Peptone, 0.5% yeast extract, 0.27% Na 2 HP0 4 , 0.115% Citric Acid pH 5.0) (Hestirin and Schramm, J. Gen. Microbiol., 11:123, 1954) and cultured in 30°C for 72 hours. Approximately 2,000 colonies were selected and were initially inoculated in 5ml MRS liquid medium and BSH liquid medium at 30°C for 72 hours and cultured without shaking. The microorganism which form a membrane shape on upper layer of the liquid medium and the microorganism which form capsule-shaped extracellular polysaccharide and of which medium was transparent, were selected. These microorganisms were inoculated again in 5 ml of MRS liquid medium and BSH liquid medium and stirred at 30°C and the absorbance thereof was measured at 600 nm by spectrophotometer. Microorganisms were diluted with BSH liquid medium until the absorbance thereof reached to 0.2. 10 ML of microorganism thus diluted was inoculated into 100 ml of BSH liquid medium at 30°C for 72 hours and cultured without shaking. In order to measure the amount of extracellular polysaccharide (dietary fibers) thus produced, each medium were centrifuged at 6,000 rpm in 4°C to obtain the precipitation of microorganisms. Cell membrane were disrupted by alkali lysis in 0.1 N NaOH solution and left alone in 80°C for 30 minutes and centrifuged at 6,000 rpm in 4°C and repeated multiple times, the above process in entirety. Extracellular polysaccharide entangled like white strings were isolated and lyophilized to be measured the amount thereof. Microorganisms with high extracellular polysaccharide productivity were selected and extracellular polysaccharide productivity was compared with each other (Table 1. ) . Table 1 . Comparison of extracellular polysaccharide productivity Example 2. The morphological determination and characteristics of the selected BC-Y009 and BC-Y058 Microorganisms which show high polysaccharide productivity selected from the Example 1 were BC-Y009, BC- Y002, BC-Y015, BC-Y026, BC-Y058, BC-Y112, BC-Y130, and BC- Y201. Upon observing partial DNA sequences, BC-Y009, BC- Y002, BC-Y015 and BC-Y026 were microorganisms of Lactobacillus genus , and BC-Y058, BC-Y112, BC-Y130 and BC- Y201 were microorganisms of Acetobacter genus . Among these bacteria, BC-Y009 and BC-Y058 which show high polysaccharide productivity were inoculated in MRS and BSH liquid mediums at 30°C for 72 hours and cultured in suspension. Cultured mediums were centrifuged at 6,000 rpm in 4°C to obtain microorganisms and the nucleic acids thereof were isolated by means of using the CTAB/NaCl method. By using 16s rRNA consensus primer, 16s rRNA was amplified by means of PCR method, and the sequence thus obtained, was determined. BLAST analysis (NCBI, USA) on the sequence thus determined, was performed and its result showed high percentage of sequence homology with sequence of Lactobacillus hilgardii , Acetobacter xylinum , Gluconobacter sp, numerous other Lactobacillus sp. and Acetobacter sp. (Table 2. and 3.) Table 2. Comparison of 16S rRNA nucleotide sequence of Lactobacill us sp . BC-Y 009 Among , ase pairs w ic are inc u e m comparison, op rig o table indicates number of base pairs which show difference, bottom left of table indicates % homology Table 3. Comparison of 16S rRNA nucleotide sequence of Acetobacter sp. BC-Y 058 Among , ase pairs w ic are inc u e m comparison, op rig o table indicates number of base pairs which show difference, bottom left of table indicates % homology BC-Y009 is a gram-positive bacteria and 0.5 to 3.0 μ in size. It is a non-motile & short-rod shaped bacteria. It does not form spores and is facultative anaerobic. The growth temperature is between 20°C to 37 °C and pH level is 2.0 to 8.0 and optimal pH level is 4.0 to 7.0. The experimental results showed that this microorganism was condensed in milk and was negative (non-reactive) to catalase and formed white colored colony in complex medium. It was precipitated in MRS liquid medium and BSH liquid medium in form of white colored capsule. The turbidity of the liquid medium was clear and the microorganism produced extracellular polysacchardie in clear medium and in case liquid medium was shaken, the extracellular polysacchride (dietary fiber) were broken into small particles. BC-Y058 is a gram-negative bacteria, rod shaped bacteria and 0.6 to 0.8 μm in size and exists as single or a pair. It is also a non-motile and does not form spores. Growth rate thereof is slow, therefore 5 to 7 days of incubation time is needed and colonies formed are small and hard. In liquid medium, clear cellulose pellicle is formed. Ethanol, acetic acid, or lactic acid can be used as substrates and showed positive response to catalase. This microorganism produces acid by using glucose and in Hoier medium, it can not grow. Upon consideration of the result of analysis of phenotype and 16s rRNA DNA sequence, BC-Y009 was named as Lactobacill us sp. BC-Y009 and BC-Y058 as Acetobacter sp. BC-Y058. They were deposited in KCTC (Korean Collection for Type Cultures) on May 30, 2000, and the deposit number were granted as KCTC BC-Y009, KCTC BC-Y058, respectively. Example 3. The degree of decomposition of extracellular polysacchride (dietary fiber) by intestinal digestive enzymes In order to determine whether or not dietary fiber produced by said microorganisms is decomposed by intestinal digestive enzyme, lg of porcine pancreatin that shows the activity of 3xU.S .Pharmacopia ( anufactured by Sigma) and comprises amylase, lipase, protease and nuclease, was suspended in buffer solution (pH7.5) of lg of dried dietary fiber. This suspension was incubated for 7 days at 40 °C and the suspension was collected once a day and the glucose therein was analyzed quantitatively by using DNS (3,5- dinitrosalicylic acid) . The result thereof showed that dietary fibers has never been decomposed at all. Therefore, it was confirmed that the dietary fibers produced by the microorganisms of the present invention do not decompose within the intestine. Example 4. Glucose absorption rate of bacteria Glucose absorption rates of Lactobacillus acidophil us (KCTC3140), L . hilgardii (KCTC3500) known as probiotics, and the said Lactobacillus BC-Y009, Acetobacter BC-Y002, Acetobacter BC-Y058 and E . coll . , were measured in the condition of the intestine. The results are represented in Figure 1. and Table 4. As illustrated in Figure 1. and Table 4. , the microorganisms of the present invention are superior to the other lactic acid bacteria in terms of glucose absorption rate. Table 4. Glucose concentration decreased by the bacteria of unit O.D. per unit time. Example 5. Concentration and survival rate of microorganisms in the intestine after adminstering microorganisms Mouse C57BL/6J Lep ob ob/ob genetically induced of obesity and diabetes mellitus (hereinafter, "OB Mouse"), was starved for 18 hours and fed the composition of the present invention (the number of microorganism of the composition was 1.0 x 10 13 CFU/g) containing 1% of Lactobacillus BC- Y009, Acetobacter BC-Y058 (w/w, drying weight) for 7 days, and then the bacterial concentration in the duodenum, the jejunum, the large intestine of these mice were analyzed. In addition, the bacterial concentration in the duodenum, the jejunum, and the large intestine of the control OB mouse that had been fed the feed which does not contain the microorganisms of the present invention, were analyzed. In order to measure the amount of Lactobacillus , the duodenum, the jejunum, and the large intestine of the mouse that had been fed Lactobacillus feed and the control mice were cut out. Each surfaces of the organs were rinsed with physiological saline solution and the contents were suspended in physiological saline solution. Then, inoculated in MRS agar medium and incubated at 37 °C. 3 Days later, the amount of bacteria was measured by counting floe and by subtracting the amount of Lactobacillus in the control group to determine the change of the amount of bacteria (Table 5.). In order to confirm the existence of Acetobacter , the each organs of mouse were cut out, then rinsed the surfaces of the organs with physiological saline solution. The contents were suspended in physiological saline solution, then inoculated in BSH liquid medium and cultured at 37 °C for 3 days. By checking the pellicle appeared on top layer of the liquid medium, the existence of fiber-producing Acetobacter was confirmed (Table 6.). According to the results represented in Table 5. and Table 6., the said two kinds of microorganisms were both able to proliferate in the intestine. Table 5. The amount of Lactobacillus sp . in the duodenum, the jejunum, and the large intestine of mouse Table 6. The amount of Acetobacter sp . in the duodenum, the jejunum, and the large intestine of mouse Example 6. The change in blood glucose level upon feeding of BC-Y009 and BC-Y058 100G of mouse feed purchased from SAMYANG Co. and 400g of Korean rice were mixed to make the composition of which carbohydrate content was 60%, then 5g of dried Lactobaccillus BC-Y009 or Acetobacter BC-Y058 were added thereto to prepare a lyophilized tablet. This tablet was fed by mouse with water . All mice used in this Example were female and OB mice. Acetσjacter feed group (OB-058), Lactobacill us feed group (OB-009), and the control group (OB-con, which has no microorganism of the present invention in the feed) were bred separately. The breeding condition was that there was light every 12 hour intervals ( 9 : 00-21 : 00 lighted, 21:00- 9:00 no lighted) and maintained 20 to 24°C of temperature and 40 to 60% of humidity. Additionally, the enteric coating solution was sprayed on dried Lactobacillus BC-Y009 or Acetobacter BC-Y058 to produce the compostion of the present invention which comprises enteric coated microorganism. The weight of the enteric coating of material included on the composition is approximately 16 to 30 mg or less per 1 tablet. The materials for the enteric coating were selected from common high molecular weight materials such as cellulose acetate phthalate, trimelitate, copolymer of methacrylic acid(Methylacrylic acid 40% or more, especially methylacrylic acid including hydroxypropyl metylcellulose phthalate and its ester derivatives), or mixture thereof. Methylacrylate used in the Example was Endragit L 100- 55 manufactured by Rohm GmbH (Germany) , cellulose acetate phthalate with about 45 to 90 cP of viscosity, 17 to 26% of acetyl content and 30 to 40% of phthalate content, or cellulose acetate trimelitate manufactured by the Eastman Kodak Company (approximately 15 to 20 cS of viscosity, 17 to 26% of acetyl content and 25 to 35% of trimelityl content ) . The enteric coating was produced by the conventional coating process wherein the enteric coating solution was sprayed on the core. The solvent of Ethanol and acetone mixture was used and the softening agent was added to the coating solution in ratio of 1 to approximately 0.005 or 0.3. The enteric coating composition of the present invention produced by means of the said process was provided with water to mouse for taking freely. The blood glucose level of the mouse which has taken the enteric coating composition, was measured. Before measuring the blood glucose level of each mouse group, each mouse were starved for 18 hours. Following 60 minutes after starvation, sufficient amount of feed was provided and after the 60 minute period, from the retroorbital venous plexus, serum was collected by using of anti-coagulating agent-free capillary tubes. The blood glucose level was measured by means of the absorbance at 505nm, by using the Trinder kit (Cat. 315-500, Sigma, USA) which employs enzyme coloring method. The statistical error of the results was indicated by average ± standard deviation per experimental group, and statistical significance of the average difference in each group was tested through ANOVA (p<0.02). Data for blood glucose level are illustrated in Figure 2. As illustrated in the Figure 2, the blood glucose level for OB-con group is approximately 500 g/dl, whereas OB-058 blood glucose level is low. Additionally, due to administration of Acetobacter BC-Y058 and Lactobacillus BC- Y009, the blood glucose levels of each mouse had been decreased to approximately 70% and 53% each(Table 7.). Table 7. The change of blood glucose level after administration of Acetobacter BC-Y058 and Lactobacillus BC-Y009 Example 7. The change of weight and amount of diet due to taking BC- Y058 and BC-Y009 and in metabolic efficiency Mice were classified as OB-058 group, OB-009 group, OB-con group, and Acetobacter BC-Y058 and Lactobacillus BC- Y009 were administered on each groups and measured the weight of each mouse in weekly interval. Along with the measuring of changes in weight, the weight of feed consumed by mouse were also measured, therefore changes of metabolic efficiency of each groups were investigated. The difference of weight change was apparent in each species of which genetic characteristics were different, but the difference of weight change, within the group of which genetic characteristics were same, was negligible. As indicated in Table 8., the weight change of OB mice within the period of 7 weeks, regardless the administration of Acetobacter BC-Y058 or Lactobacillus BC-Y009, was approximately 47% increase of weight. However, on the contrary, as indicated in Table 9. and Table 10., feed consumption percentage, depending on microorganism administration, increased 17 to 24% in OB mice group. That is, in case of consuming feed which comprises the microorganisms of the present invention, the weight increase was same as that of consuming feed that does not contain the microorganism of the present invention. The results indicate that Acetobacter BC-Y058 and Lactobacillus BC-Y009 suppress blood glucose level increase after meal and therefore as a compensation, much more feed can be consumed. Because of the conversion of glucose into dietary fiber by BC-Y058 and BC-Y009 microorganism, metabolic efficiency had been changed. According to the formula represented below, the change of energy efficiency depends on feed consumption, was calculated and represented in Table 10. energy metabolic efficiency = (weight gain( g) /amount of feeding(g)) X 1,000 As represented in Table 10, in case microorganisms were administered on OB mouse, the energy metabolic efficiency was 75 to 85% (Figure 3.) when compared with that of the control group which was not administered with the microorganisms of the present invention. Table 8. Change of the mouse weight (g) Table 9 . Change of amount of feed consumption according to the administration of Acetobacter BC-Y058, Lactobacill us BC- Y009(g) Table 10. Energy metabolic efficiency Example 8. Lipid level changes when BC-Y058 and BC-Y009 were administered After administration of the microorganisms of the present invention, the change of blood lipid, especially cholesterol change were analyzed and confirmed whether or not the microorganisms affected the circulatory disease such as artheriosclerosis and myocardial infarction besides diabetes mellitus and obesity. Lipid analysis was performed by means of enzyme coloring method as in Example 6, by using TG-glycezyme-V (Young-Yeoun Chemical Co., Japan), HDL-zyme-V (Young-Yeoun Chemical Co., Japan), Cholestezyme-V (Young-Yeoun Co., Japan), LDL cholesterol (Cat. 61532, BioMeriux, France), to measure the absorbance at 505 to 570nm with standard solution, and thus amount of lipid in blood was calculated. As represented in Table 11., lipid concentration before feed administration did not show any differences in obese mouse. However, after Acetobacter BC-Y058 and Lactobacillus BC-Y009 were administered, as indicated in Table 12., the change of lipid concentration was apparent after 7 weeks . In case of obese mice that have taken the microorganism, the lipid level did not change in comparison with the data of early steps in the present experiment and however, in case of control mouse which had not been administered with the microorganisms, overall lipid content in blood was increased. Table 11. Lipid amount in blood before administration of feed (mg/dl) TG : Triglyceride HDL-C : High Density Lipoprotein Cholesterol LDL-C : Low Density Lipoprotein Cholesterol Table 12. Lipid amount in blood after administration of feed (mg/dl) TG : Triglyceride HDL-C : High Density Lipoprotein Cholesterol LDL-C : Low Density Lipoprotein Cholesterol The industrial applicability of the present invention The microorganisms of the present invention can live within the intestine and convert monosaccharides and disaccharides into high molecular weight material which cannot be absorbed and hardly digestible in the intestine, thus reducing remarkably the amount of monosaccharide to be absorbed and induce that the energy required in metabolic activity, are provided from lipids and protein accumulated in the body, thus suppressesing obesity and diabetes mellitus, effectively. In addition, the microorganisms of the present invention produce dietary fibers within the intestine and excreting harmful materials along with these dietary fibers, to prevent appendicitis, large intestinal cancer, and to suppress cholesterol absorption, and to clean intestine. While the present invention has been particularly shown and described with reference to particular examples thereof, it will be understood by those skilled in the art that various changes in form and details may be conceived therefrom without departing from the spirit and scope of the present invention as defined by the appended claims .
