     BEST MODE 
     Lactic acid bacteria are bacteria producing lactic acid by degrading sugar such as glucose. The lactic acid produced by lactic acid fermentation of lactic acid bacteria may prevent growth of pathogens and harmful bacteria, and this characteristic is used for producing foods such as dairy foods, kimchis, brewed foods and the like. Further, the lactic acid bacteria live in the intestine of mammals and inhibit abnormal fermentation by various germs, and therefore, those are important bacteria useful as a medicine for intestinal disorders. 
       Lactobacillus plantarum  is a strain belongs to the lactic acid bacteria, and it is known to mainly grow when kimchi is much fermented and tastes sour. Optical isomers of the produced lactic acid are D-type and L-type. The  Lactobacillus plantarum  may be widely used to various foods need fermentation. Accordingly, if a  Lactobacillus plantarum  having excellent acid resistance, bile acid resistance and antibacterial activity is developed, it may be usefully used. 
     Hereinafter, the present disclosure now will be described in detail. 
     One aspect of the present disclosure provides a  Lactobacillus plantarum  APsulloc 331261 (Accession No.: KCCM11179P) strain. One aspect of the present disclosure provides a  Lactobacillus plantarum  APsulloc 331263 (Accession No.: KCCM11180P) strain. One aspect of the present disclosure provides a  Lactobacillus plantarum  APsulloc 331266 (Accession No.: KCCM11181P) strain. One aspect of the present disclosure provides a  Lactobacillus plantarum  APsulloc 331269 (Accession No.: KCCM11182P) strain. 
     At least one of the  Lactobacillus plantarum  APsulloc 331261, the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 according to the present disclosure is a strain isolated from tea tree ( Camellia sinensis ) leaves, and belongs to  Lactobacillus plantarum . Specifically, the  Lactobacillus plantarum  strain according to the present disclosure may be isolated by a method containing: a step of salting the tea tree leaves in salt of 5 to 15 wt %, based on the weight of the tea tree leaves; a step of mixing the salted tea tree leaves with a sugar solution, for example, 0.1% to 3% fructooligosaccharide, followed by culturing at 25 to 35° C. for 1 to 5 days; and a step of collecting the solution cultured to less than pH 5, followed by culturing at anaerobic condition of 25 to 35° C. for 1 to 5 days. 
     At least one of the  Lactobacillus plantarum  APsulloc 331261, the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 according to one aspect of the present disclosure has excellent acid resistance. When intaking lactic acid bacteria, for example,  Lactobacillus plantarum  as a probiotic, it is preferred to have higher intestinal deliverity, in order to display characteristic effects of the lactic acid bacteria. In order to enhance the intestinal deliverity, viability in the stomach, where pH is low due to gastric acid secretion, should be high. It is known that pH of the empty stomach may be about 1.2 to 2, but when taking foods, pH may be about 2 to 3. The  Lactobacillus plantarum  strain according to the present disclosure may have excellent acid resistance at more than pH 2 to 4, specifically more than pH 2 to 3.5 or pH 2.5 to 4, more specifically pH 2.5 to 3.5, further more specifically about pH 2.5 to 3. On the other hand, when intaking foods, it is known that the average retention time of the foods may be about 1 to 3 hours. The  Lactobacillus plantarum  strain according to the present disclosure may have excellent acid resistance for 0.5 to 5 hours, specifically for 1 to 4 hours, at more than pH 2 to pH 4, specifically more than pH 2 to pH 3.5 or pH 2.5 to 4, more specifically pH 2.5 to 3.5, further more specifically pH 2.5 to 3. Thus, the  Lactobacillus plantarum  strain according to the present disclosure, which is viable even at lower pH of the stomach during the time stayed in the stomach, may have high intestinal deliverity when it is taken as a food. 
     The  Lactobacillus plantarum  strain according to one aspect of the present disclosure has excellent bile acid resistance. The foods passed through the stomach are delivered into the intestine, and at this time, the secreted bile acid helps food digestion. It is known that the strain having high bile acid resistance has good intestinal fix. The  Lactobacillus plantarum  strain according to one aspect of the present disclosure having excellent bile acid resistance is superior to the intestinal fix. 
     The  Lactobacillus plantarum  strain according to one aspect of the present disclosure has lactic acid producing ability. In general, the lactic acid produced by lactic acid bacteria may be L-type and D-type. Of them, the metabolic rate of the D-lactic acid in the body is lower than the L-lactic acid. Accordingly, the higher blood D-lactic acid concentration may cause lactic acid toxicosis. Thus, it is preferred that adults or infants, who are susceptible to lactic acid, do not take lactic acid bacteria, which largely produces D-lactic acid, if possible. 
     The  Lactobacillus plantarum  strain according to another aspect of the present disclosure may produce lactic acid containing D-type in an amount of 75% or less, specifically 70% or less, more specifically 65% or less. 
     The  Lactobacillus plantarum  strain according to further another aspect of the present disclosure may produce lactic acid in an amount of 17.5 g/L or less, specifically 17 g/L or less, more specifically 16.5 g/L or less, further more specifically 15 g/L or less, further more specifically 14.5 g/L or less, further more specifically 14 g/L or less, further more specifically 13.5 g/L or less. 
     Like this, because the  Lactobacillus plantarum  strain according to the present disclosure produces lactic acid containing D-type with lower rate than the existing  Lactobacillus plantarum , adults or infants, who are susceptible to lactic acid, may freely take it. Further, because its lactic acid yield is lower than the existing  Lactobacillus plantarum , when fermenting foods by using thereof, the foods may have gentler flavor. 
     One aspect of the present disclosure provides an extract or a culture solution of at least one of the  Lactobacillus plantarum  APsulloc 331261 strain, the APsulloc 331263 strain, the APsulloc 331266 strain and the APsulloc 331269 strain. Another aspect of the present disclosure provides a composition containing at least one of the  Lactobacillus plantarum  APsulloc 331261 strain, the APsulloc 331263 strain, the APsulloc 331266 strain and the APsulloc 331269 strain, an extract thereof, or a culture solution thereof.

     Hereinafter, isolation methods, identification methods and characteristics of the novel  Lactobacillus plantarum  strains according to the present disclosure now will be described in detail with reference to the examples (and experiments). However, the following examples (and experiments) are for illustrative purposes only and not intended to limit the scope of this disclosure. 
     [Example 1] Isolation of  Lactobacillus Plantarum  Strain 
     Tea tree leaves 200 g are washed twice with distilled water to remove impurities. Moisture is cleared off from the washed tea tree leaves. Then, the tea tree leaves are mixed with table salt of 8 wt %, based on the weight of the tea tree leaves, and then stored at room temperature for 3 hours. The salted tea tree leaves are mixed with 1% fructooligosaccharide solution 1000 mL, and then incubated in an incubator at 32° C. for 3 days. 3 days later, whether pH of the cultured solution is lowered to less than 5 is checked, and in the case of less than pH 5, the cultured solution is collected and incubated in Difco Lactobacilli MRS Agar® medium. At this time, the incubation is conducted in a 32° C., anaerobic chamber for 2 days, and then white colonies are collected. 
     Through the method described above,  Lactobacillus plantarum  APsulloc 331261, APsulloc 331263, APsulloc 331266 and APsulloc 331269 are isolated from tea tree leaves, respectively. 
     [Example 2] Identification of  Lactobacillus Plantarum  Strain 
     (1) Strain Culture 
     The APsulloc 331261 isolated in Example 1 is streaked on a MRS agar plate, and cultured at 37° C. for 2 days. The obtained single colony is inoculated to MRS broth 10 mL, and then cultured at 37° C. overnight to prepare a  Lactobacillus plantarum  strain culture solution. The method described above is repeated to the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269, respectively, to prepare  Lactobacillus plantarum  strain culture solutions. 
     (2) Analysis of Sugar Fermentation Pattern of  Lactobacillus Plantarum  Strain 
     The APsulloc 331261 strain culture solution prepared as described in (1) is inoculated to MRS broth 10 mL to the concentration of 0.5% and cultured at 37° C. overnight. The culture solution is centrifuged at 8,000 rpm for 5 min, supernatant is removed, and then only bacteria are collected. Then, 0.85% saline buffer 2 mL is added to the bacteria and suspended. Later process is conducted by using API 50CHL kit (Biomerieux) according to a manufacturer&#39;s protocol. Specific process is as follows. 
     First of all, while gradually adding the strain suspension to API suspension medium 5 mL, the amount of suspension needed to make cloudiness of about McFarland Standard 2 (Biomerieux) is measured. Twice of the measured amount of the suspension is added to API 50CHL medium 10 mL, and then shaken for mixing. The above mixture is added to cupules containing different substrate, one drop of mineral oil is put thereto, and then the mixture is cultured at 37° C. for 2 days to analyze sugar fermentation pattern. 
     The method described above is repeated to culture solutions of the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 strain to analyze sugar fermentation pattern. 
     The results of sugar fermentation patterns of the APsulloc 331261, the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269, compared with  Lactobacillus plantarum  strain (KCTC3108) as a standard strain, and the results of identification of the APsulloc 331261, the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 by using the above results are as shown in the following Tables. Table 1: APsulloc 331261, Table 2: APsulloc 331263, Table 3: APsulloc 331266 and Table 4: APsulloc 331269.

     As can be seen from the above, all of the APsulloc 331261, the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 show the consistency (% index) to the  Lactobacillus plantarum  of 99% or more. Accordingly, it is confirmed that those strains are belong to the  Lactobacillus plantarum.    
     Further, compared with the standard strain (KCTC3108), the APsulloc 331261 is different in use of α-methyl-mannoside and raffinose, the APsulloc 331263 is different in use of α-methyl-mannoside, raffinose and D-turanose, the APsulloc 331266 is different in use of α-methyl-mannoside and raffinose, and the APsulloc 331269 is different in use of L-arabinose and raffinose. Accordingly, it is confirmed that all of them are different strains from the standard strain. 
     (3) Analysis of Enzyme Activity Pattern of  Lactobacillus Plantarum  Strain 
     The APsulloc 331261 strain culture solution prepared as described in (1) is inoculated to MRS broth 10 mL to the concentration of 0.5% and cultured at 37° C. overnight. The culture solution is centrifuged at 8,000 rpm for 5 min, supernatant is removed, and then only bacteria are collected. Then, 0.85% saline buffer 2 mL is added to the bacteria and suspended. Later process is conducted by using API ZYM kit (Biomerieux) according to a manufacturer&#39;s protocol. Specific process is as follows. 
     First of all, while gradually adding the strain suspension to API suspension medium 5 mL, the amount of suspension needed to make cloudiness of about McFarland Standard 2 (Biomerieux) is measured. Twice of the measured amount of the suspension is added to API 50CHL medium 10 mL, and then shaken for mixing. The above mixture 65 μl is added the each cupule, and cultured at 37° C. for 4 hours. Each one drop of ZYM A reagent and ZYM B reagent is put into each cupule, and 5 min later, scored from 0 to 5 according to the color intensity, and then the score 3 or more is decided as positive. 
     The method described above is repeated to the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 strain culture solution to analyze enzyme activity patter. 
     The results of enzyme activity patterns of the APsulloc 331261, the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269, compared with  Lactobacillus plantarum  strain (KCTC3108) as a standard strain are as shown in the following Tables. Table 6: APsulloc 331261, Table 7: APsulloc 331263, Table 8: APsulloc 331266 and Table 9: APsulloc 331269.

     As can be seen from the above, all of the APsulloc 331261, the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 have different enzyme activity intensities of acid phosphatease, naphthol-AS-BI-phosphohydrolase, α-galactosidase and N-acetyl-β-glucosaminidase from the standard strain (KCTC3108). Accordingly, it is confirmed that all of the APsulloc 331261, the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 are different strains from the standard strain. 
     Further, the APsulloc 331261, the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 are decided as negative against the β-glucuronidase activity known as one of representative oncogenic enzymes, which can induce cancer by modifying procarcinogen to carcinogen in the intestine. In addition, the APsulloc 331263 inhibits the α-glucosidase activity. Accordingly, it is confirmed that all of the APsulloc 331261, the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 are acceptable to be used to a food composition. 
     (4) Evaluation of Antibiotic Resistance of  Lactobacillus Plantarum  Strain 
     Sterilized MRS agar 20 mL is added to a petri dish (Diameter: 100 mm), and cooled in a clean bench to prepare a medium. The APsulloc 331261 strain culture solution prepared in (1) is inoculated to MRS broth 10 mL to the concentration of 0.5%, and then cultured at 37° C. for 6 hours. The resulting solution is diluted to have absorbance of about 0.08 to 0.13 at 625 nm. A sterilized cotton swab is fully soaked in the diluted solution, and then streaked evenly on the prepared MRS agar plate overall. An antibiotic sensitivity disk is dropped on the plate with a proper distance. After culturing at 37° C. for 24 hours, diameter of a clear zone is measured. 
     The method described above is repeated to the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 strain culture solutions to evaluate antibiotic resistance. 
     Concentration of the antibiotic sensitivity disk and evaluation standard are as follows.

     As can be seen from the above, compared with the standard strain (KCTC3108), the APsulloc 331261 is different in antibiotic resistance pattern of ceftazidime, clindamycin and nitrofurantoin, and the APsulloc 331263 is different in antibiotic resistance pattern of ceftazidime and nitrofurantoin. Compared with the standard strain (KCTC3108), the APsulloc 331266 is different in antibiotic resistance pattern of ceftazidime, nitrofurantoin and penicillin, and the APsulloc 331269 is different in antibiotic resistance pattern of ceftazidime, clindamycin, nitrofurantoin and penicillin. Accordingly, it is confirmed that all of the APsulloc 331261, the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 are different strains from the standard strain. 
     When analyzing sugar fermentation pattern, enzyme activity pattern and antibiotic resistance pattern overall, it is confirmed that all of the APsulloc 331261, the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 are belong to the  Lactobacillus plantarum , and are different strains from the  Lactobacillus plantarum  standard strain (KCTC3108). 
     [Test Example 1] Acid Resistance Evaluation 
     (1) Acid Resistance Evaluation Depending on pH 
     The APsulloc 331261 strain culture solution is inoculated to MRS broth 10 mL to the concentration of 0.5%, and cultured at 37° C. overnight. pH is controlled to 2.0, 2.5, 3.0, 3.5, respectively, with HCl. The culture solution 50 μl is inoculated to sterilized MRS broth 5 mL, and then cultured at 37° C. for 1 hour. After 1 hour, the culture solution is diluted with peptone saline buffer solution to measure the number of bacteria per mL. After measuring the number of bacteria in the culture solution, viability is calculated by considering the value multiplying the number by 0.01 as control, and considering the number of control bacteria as 100%. 
     The method described above is repeated to the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 strain culture solutions to evaluate acid resistance depending on pH. 
     The results of comparing acid resistance of the APsulloc 331261, the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 with the  Lactobacillus plantarum  strain (KCTC3108) as a standard strain are shown in the following Tables. Table 13: APsulloc 331261 and APsulloc 331263, and Table 14: APsulloc 331266 and APsulloc 331269.

     As can be seen from the above, all of the APsulloc 331261, the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 show higher viability at about pH 2.5 to 3.5 than the standard strain. Namely, it is confirmed that the above  Lactobacillus plantarum  strains have excellent acid resistance. When considering pH of the stomach with foods is about 2 to 3, it is confirmed that the  Lactobacillus plantarum  strains may have higher viability in the stomach when contained in the food composition. 
     (2) Acid Resistance Evaluation Depending on Time 
     The APsulloc 331261 culture solution is inoculated to MRS broth 10 mL to the concentration of 0.5%, and cultured at 37° C. overnight. The culture solution 50 μl, which is controlled to pH 2.5 with HCl, is inoculated to sterilized MRS broth 5 mL, and cultured at 37° C. for 3 hours. After each 1 hour and 3 hours, the culture solution is diluted with peptone saline buffer solution, and then the number of bacteria per mL is measured. After measuring the number of bacteria in the culture solution, viability is calculated by considering the value multiplying the number by 0.01 as control, and considering the number of control bacteria as 100%. 
     The method described above is repeated to the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 strain culture solutions to evaluate acid resistance depending on time. 
     The results of comparing acid resistance of the APsulloc 331261, the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 with the  Lactobacillus plantarum  strain (KCTC3108) as a standard strain are shown in the following Tables. Table 15: APsulloc 331261 and APsulloc 331263, and Table 16: APsulloc 331266 and APsulloc 331269.

     A can be seen from the above, it is confirmed that all of the APsulloc 331261, the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 have higher viability at pH 2.5 even after 1 hour and 3 hours, respectively, than the standard strain. Namely, it is confirmed that all of the above  Lactobacillus plantarum  strains have excellent acid resistance for a long time. When considering average retention time of the intaken foods in the stomach is about 1 to 3 hours, it is confirmed that the  Lactobacillus plantarum  strains may have higher viability during the time stayed in the stomach when contained in the food composition. 
     Thus, all of the APsulloc 331261, the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 are viable even at lower pH of the stomach during the time stayed in the stomach. Accordingly, when the strains are intaken as a food, those are viable in the stomach, and further, have high intestinal deliverity. 
     [Test Example 2] Bile Acid Resistance Evaluation 
     The APsulloc 331261 culture solution is inoculated to MRS broth 10 mL to the concentration of 0.5%, and cultured at 37° C. overnight. Ox gall is added thereto to the concentration of 0.3% and 0.5%, respectively, to prepare a MRS agar plate. MRS agar where the ox gall is not added is used as control. After diluting the strain culture solution and streaking on MRS agar medium, the plate is cultured at 37° C. for 2 days. The results of calculating the number of each colony and the viability (%) of the APsulloc 331261 when considering the number of control bacteria as 100% are shown in the following Tables. The method described above is repeated to the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 strain culture solutions to evaluate bile acid resistance, and then the results thereof are shown in the following Tables. Table 17: APsulloc 331261 and APsulloc 331266, and Table 18: APsulloc 331263 and APsulloc 331269.

It is known that the strain having excellent bile acid resistance is also excellent in intestinal fix. Accordingly, it is confirmed that all of the APsulloc 331261, the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 have excellent intestinal fix and intestinal deliverity. 
     [Test Example 3] Lactic Acid Producing Ability Evaluation 
     The APsulloc 331261 strain culture solution is inoculated to MRS broth 10 mL to the concentration of 0.5% and cultured at 37° C. overnight. The culture solution is centrifuged at 8,000 rpm for 15 min, only supernatant is collected. The collected supernatant is treated at 80° C. for 15 min to stop enzyme reaction. The heat treated supernatant is diluted 100 times with distilled water. Later process is conducted by using D-lactic acid/L-lactic acid UV method kit (R-biopharm) according to a manufacturer&#39;s protocol. Specific process is as follows 
     Kit solution 1 (glycylglycine buffer/L-glutamate) 1 mL, solution 2 (NAD solution) 0.2 mL and GPT suspension solution 3 0.02 mL are sequentially added to a cuvette. The supernatant prepared above 0.1 mL is added to the cuvette. Deionized water 1 mL is added to control, and deionized water 0.9 mL is added to the sample followed by well mixing thereof. After 5 min, absorbance (A1) is measured at 340 nm. D-LDH solution 4 0.02 mL is added thereto, and mixed well followed by reacting for 30 min. Absorbance (A2) is measured at 340 nm. L-LDH solution 5 0.02 mL is added thereto, and mixed well followed by reacting for 30 min. Absorbance (A3) is measured at 340 nm. The concentrations of D-lactic acid and L-lactic acid in samples are calculated according to a calculating method. The results compared with the  Lactobacillus plantarum  strain (KCTC3108) as a standard strain are shown in the following Table. 
     The method described above is repeated to the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 strain culture solutions to evaluate lactic acid producing ability, and the results thereof are shown in the following Tables.

     As can be seen from the above, all of the APsulloc 331263, the APsulloc 331266 and the APsulloc 331269 produce D-lactic acid and L-lactic acid. Further, the total lactic acid yields of them are smaller than the standard strain, and the ratio of the D-lactic acid to the produced lactic acid is low. Accordingly, foods containing the  Lactobacillus plantarum  strains may be freely taken to adults or infants, who are susceptible to lactic acid, and when foods are fermented by using the  Lactobacillus plantarum  strains, the foods may have gentler flavor.

     (1) APsulloc 331261 
     The APsulloc 331261 culture solution is inoculated to MRS broth 10 mL to the concentration of 0.5%, and cultured at 37° C. overnight. Sterilized MRS agar 15 mL is aliquoted to a petri dish to prepare a medium, and then each 1 μl of the APsulloc 331261 culture solution is spotted thereon, and cultured at 37° C. for 24 hours. 
     On the other hand,  Shigella flexneri  is streaked on Tryptic soy agar, and cultured at 37° C. overnight. Then a colony is inoculated to BHI broth and cultured overnight. BHI soft agar (agar 1%) is sterilized and cooled to about 45 to 50° C., and then  Shigella flexneri  culture solution 1% is inoculated thereto. 
     The  Shigella flexneri  culture solution 10 mL is overlaid on the APsulloc331261 culture solution and hardened. After culturing at 37° C. for 24 hours, size of a clear zone is measured. The results compared with the  Lactobacillus plantarum  strain (KCTC3108) as a standard strain are shown in the following Table.

     (3) APsulloc 331269 
     The APsulloc 331269 culture solution is inoculated to MRS broth 10 mL to the concentration of 0.5%, and cultured at 37° C. overnight. The culture solution is centrifuged at 8000 rpm for 5 min, and only supernatant is collected. The supernatant 10 mL is prepared by sterilizing with a 0.22 μl syringe filter. 
     On the other hand,  Salmonella typhimurium  and  Staphylococcus aureus  are streaked on Tryptic soy agar, respectively, and cultured at 37° C. overnight. Then a colony is inoculated to BHI broth and cultured overnight. 
     BHI agar is sterilized, and 20 mL thereof is put into a petri dish and cooled to prepare a medium.  Salmonella typhimurium  and  Staphylococcus aureus  culture solutions are diluted 50 times with sterilized physiological saline solution, respectively, and then streaked evenly on the medium prepared above with a sterilized cotton swab. A sterilized paper disk is put thereon, and the supernatant of the APsulloc 331269 culture solution prepared above 100 μl is dropped on the paper disk. The medium is stored at room temperature for about 3 hours for absorption, and then cultured at 37° C. for 24 hours. Size of a clear zone is measured, and the results compared with the  Lactobacillus plantarum  strain (KCTC3108) as a standard strain are shown in the following Table.
