     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a water purificant in the field of aquiculture, agriculture, horticulture, floriculture and waste-water treatment, which are effective as media to cells of microorganisms, fishes, plants and animals in water and soils. The water purificant for the uses of aquaculture, agriculture, horticulture, floriculture and waste-water treatment increase the diversity of microorganisms in water and soils and activate microorganisms, plants, animals, fishes. 
     2. Description of the Prior Art 
     The minimal media containing carbon sources, nitrogen sources and minerals (Na, K, Mg and Fe) were well known to grow microorganisms, fishes, plants and animals (References: David Freifelder (Translated by M. Kawakita), Introduction to molecular biology, 2p (1985), Tokyo Kagaku Dojin, Tokyo; Thomas D. Brock, Biology of microorganisms, (1970), Prentice-Hall, Inc., New Jersey). 
     But, different species of microorganisms, fishes, plants and animals prefer different optimum media. Common minimal media can not exist for all species. For example, in the case of microorganisms, the categories of prototroph and auxotroph and their nutritional factors are different. 
     In the case of growing microorganisms, plants, animals and fishes in hydrosphere and pedosphere, the nutrition in media was consumed in accordance with the nutritional demands of species, and the residual factors in media were concentrated in the broth or soils. The concentrated residues in media produce replant failure or virus disease in plants and fishes. (Reference: I. Horiuchi, E. Idaka, S. Komura, Advanced biotechnical treatment of water in intensive prawn culture system, 19th Congress on Science and Technology of Thailand, 89p, (27-29, October, 1993, Dusit J. B. Hotel, Hat Yai, Songkhla)). 
     In the case of minerals, the elements of secondary nutrients (Ca, Mg, Si, S) and micronutrients (Mn, B, Fe, Cu, Zn, Mo, Cl) are so called essential minerals for plant growth (References: E. Epstein, Mineral nutrition of plants: Principles and perspectives, (1972), John Wiley and Sons, Inc., New York; Ed. by F. E. Brear, Chemistry of the soil, (1969), Van Nostrand Reinhold Co., New York). But, so called minerals involved more than 100 kinds of elements and enormous chemical species in which involved stable, metastable, unstable isotopes and their cluster forms. So the true essential minerals can not be supplied by adding bittern from surface marine water. 
     In the results, the diversity of minerals in hydrosphere and pedosphere decreased, the replant failure by nematode and the annihilation of black tiger prawn (Penaeus monodon) occurred and resulting predominant species degradin healthy food chain occurred. The phenomena in accordance with the lack of mineral balance were as follows: 1. Zoogloea bulking in activated sludge treatment (Reference: R. Sudo, Biology of Wastewater Treatment, 311p, Sangyo Yosui Chosakai, Tokyo, Japan (1977); Ed. by Soc. Civil Engineering, Sanitary Engineering Commity, Research Methods for Environmental Sanitary Engineering, Gihodo Shuppan, Tokyo, Japan (1993)); 2. phytoplankton bloom in eutrophic lakes (Reference: Ed. by M. Watanabe, K. Harada, H. Fujiki, Water-bloom, Appearance and Toxicity, Tokyo University Shuppankai, Tokyo, Japan (1994)); 3. Red tide; 4. Cyst nematode in fields (Reference: T. Saegusa, Nematode, Nobunkyo, Tokyo, Japan (1993)); 5. Bursaphelenchus lignicolus in stems of Pinaceae; 6. Annihilation of prawn (C. J. Sindermann, D. V. Lightner ed., Developments in Aquaculture and Fisheries Science, 17, Disease Diagnosis and control in North American Marine Aquaculture, Elsevier, Amsterdam, (1988)); 7. Tricoderms sp., Aspergillus sp. and Penicillium sp. in culture of Agaricus silvaticus Schaeffer, Agraricus fiardii Pegler (Agaricus blazei Murrill) and Cordyceps sinensis (Berkley) Saccardo; 8. Growth of cancer, atopic dermatitis, pollinosis (Reference: Chi Changrok, Specific minerals for cancer, Gendai Shorin, Tokyo, Japan (1991)). 
     SUMMARY OF THE INVENTION 
     In view of the above-described problems, the present inventor made exhaustive studies in order to dissolve the lack of minerals in hydrosphere and pedosphere. The present inventor achieved to this invention in which the inventor treated deep marine water over 200 m depth or from upwelling to collect bittern and after then it was concentrated and treated chemically. 
     Primeval sea water or soils should contain many kinds of minerals. However, sea water or soils now lack many kinds of minerals and now lack diversity with respect to existing chemical species. Replant failure occurs when large quantities of manure and pesticide have been introduced in sea water or soils. The water purificant of this invention supplies minerals as activated states to cells of microorganisms, fishes, animals and plants. By incorporating minerals in cells, growth and immunity of cells can be increased and then, yields of plants, fishes, microorganisms and hymenocarps must be increased. 
     An object of the invention is to provide a water purificant that is for use in aquiculture, agriculture, horticulture, floriculture and waste-water treatment and that comprises bittern. 
     In one embodiment, the purificant includes acids, salts or a combination of acids and salts. Unless otherwise indicated, the word “acids” is used herein and in the claims to mean acids that are either inorganic or organic and the word “salts” is used herein and in the claims to mean salts that are either inorganic or organic. The concentration of bittern is 1 ppm-100 weight %, based upon the total weight of the composition of the purificant, i.e. bittern must exist in the composition. A very important feature is that the bittern of the composition be made or concentrated from deep marine water such as exists 200 meters or more under sea level or bittern of the same character produced from upwells. 
     The water purificant of another preferred embodiment of the present invention comprises bittern and bases in which case, the bittern may form 1 ppm-100 weight % of the water purificant. Further, according to other preferred embodiments, the water purificant may contain a basic poly-saccharide such as chitin or chitosan, which may form 10-20000 ppm of the water purificant. 
     Further, according to the preferred embodiments, the bittern solution is made from deep marine water which exists at or more than 200 m below the sea level. In this case, the deep marine bittern solution may form 1 ppm-100 weight % of the water purificant. 
     The above and further objects, features, aspects, and advantages of the present invention will be more fully apparent from the following detailed description.

     DETAILED DESCRIPTION OF THE INVENTION 
     The first preferred embodiment of the water purificant for the uses of aquaculture, agriculture, horticulture, floriculture and waste-water treatment in this invention is obtainable by adding acids and/or salts in bittern concentrated from deep marine water which exists at or more than 200 m below the sea level, or from upwelling water (Reference: B. H. McConnaughey, Introduction to marine biology, 10, (1970), The C. V. Mosby Co., St Louis). For example, the specific gravity of the bittern solution is 1-1.4 g/cm3. In the case of adding these water purificant to hydrosphere or pedosphere under dilution, they activate and increase the diversity of microbiota, fauna and flora. 
     Also, an ion contained in the water purificant activates and dissolves oxygen.

     By acute toxicity test (20 ml/kg-weight was administrated orally) to 10 mice (ddy, 5 week old, male, 2 groups) all mice were living. 
     Standard method analysis of water with 10000 dilution after 24 h at r.t. was as follows: standard plate count=0 count/ml, coliform group=0 count/ml, Cd&lt;0.001 mg/ml, Hg&lt;0.005 mg/l, Se&lt;0.001 mg/l, Pb&lt;0.005 mg/l, Ba&lt;0.1 mg/l, As&lt;0.005 mg, Cr(VI)&lt;0.005 mg/l, CN&lt;0.01 mg/l, NO2+NO=2.6 mg/l, F&lt;0.1 mg/l, H3BO4&lt;1.0 mg/l, Zn&lt;0.005 mg/l, Cu&lt;0.01 mg/l, Mn&lt;0.005 mg/l, organic matter=2.2 mg/l, sulphide&lt;0.05 mg/l. The analytical results come up to the standard mineral water.

     Concentrations of bittern and acids were as follows: bittern, 1 ppm-100%; acids, 1 ppm-50%. 
     In the case of adding the water purificant of the invention, 1000-10000 folds dilution of the formulated concentrate of the water purificant is optimal for environmental water. In the case of water culture, 10000-100000 folds dilution is optimal. 
     The range of the specific gravity (d) of the bittern concentrated from deep marine water (collected depth over 200 m) of this invention is 1.2-1.4. The activity of the water purificant depends on the specific gravity of the bittern. 
     In the case of agar culture (with SMY (sucrose-malt extract-yeast extract) media) of Agaricus silvaticus Shaeffer in the range of d=1.2-1.4, the growth rate (mm/day) was as follows: 0.4 mm/day (control), 0.5 mm/day (d=1.2), 0.55 mm/day (d=1.3), 0.62 (d=1.4). Therefore, the activity of the water purificant increased in accordance with heavier specific gravity. In the case of d=1.4, the highest growth activity showed. 
     In the case of agar culture of Agaricus fiardii Pegler (with SMY media) in the range of d=1.2-1.4, the growth rate (mm/day) was as follows: 0.4 mm/day (control), 0.48 mm/day (d=1.2), 0.53 mm/day (d=1.3), 0.60 (d=1.4). Therefore, the activity of the water purificant increased in accordance with heavier specific gravity. In the case of d=1.4, the highest growth activity showed. 
     In the case of agar culture of Cordyceps sinensis (Berkley) Saccardo (with SMY media) in the range of d= 1.2-1.4 , the growth rate (mm/day) was as follows: 0.26 mm/day (control), 0.30 mm/day (d=1.2), 0.35 mm/day (d=1.3), 0.40 (d=1.4). Therefore, the activity of the water purificant increased in accordance with heavier specific gravity. In the case of d=1.4, the highest growth activity showed. 
     In the case of agar culture of Aeromonas hydrophila var 24 B. (with SMY media) in the range of d=1.2-1.4, the growth rate (mm/day) was as follows: 0.24 mm/day (control), 0.3 mm/day (d=1.2), 0.34 mm/day (d=1.3), 0.42 (d=1.4). Therefore, the activity of the water purificant increased in accordance with heavier specific gravity. In the case of d=1.4, the highest growth activity showed (Reference: E. Idaka et al., Degradation of azo compounds by Aeromonas hydrophila var. 24 B, J. Soc. Dyers Colour. vol.94, 91-94 (1978)). 
     The stability of zebrinin after 5 days in the range of d=1.2-1.4 at pH 6.5 was as follows:55% (control), 58% (d=1.2), 64% (d=1.3), 68% (d=1.4). In the case of the d=1.4, the highest stability of zebrinin was shown (Reference: E. Idaka et al., Structure of zebrinin, a novel acylated anthocyanin isolated from Zebrina pendula, Tetrahedron Lett., vol.28 (17) 1901-1904 (1987)). The pH range of the water purificant was tested in the range of pH5-pH11. The pH range was prepared with mixed mineral acid solution of phosphoric acid and sulfuric acid (2:1) for acidic range and calcium hydroxide for basic range. In the case of agar culture (with MY media) of Agaricus silvaticus Shaeffer in the range of pH5-pH11, the growth rate (mm/day) was as follows: 0.4 mm/day (control), 0.2 mm/day (pH5), 0.3 mm/day (pH6), 0.54 mm/day (pH6.5), 0.50 mm/day (pH7), 0.52 mm/day (pH7.8), 0.48 mm/day (pH8.5), 0.40 mm/day (pH9.2), 0.35 mm/day (pH10.2), 0.2 mm/day (pH11). The optimum pH range was shown in the range of pH6.5-8.5.

     EXAMPLE 11 
     Formulated concentrate of the water purificant was prepared by mixing with 10% of bittern and 1% of 1N sodium hydroxide. The solution was diluted 1000-10000 folds and added in paddy field. Generally, phototrophic bacteria eliminate hazardous compounds for roots of rice and activate resiratory and metabolic system in roots. So additional spraying of phototrophic bacteria ( Chromatium okenii, Thioshirillum jenense, Thiobacillus perometabolis, Thiobacillus rubellus ) accelerated the growth of roots. The paddy fields using the water purificant of this invention should not flow out the reserved water for protection of flowing out phototrophic bacteria. In the stopped flow-paddy fields, healthy food chain was constructed continuously and healthy rice was harvested with 25% yield-up comparing to the control. The harvested rice was enhanced and tasty particle and kept life. In the case of additional spraying of boiled aquious extract or dried-up powder of water-front plants ( Salix subfragilis, Alnus japonica, Ulmus Davidiana, Acer palmatum thunb, Fraxinus mandshurica, Juglans mandshurica, Ilex serrato, Viburnum Opulus L., Hydrangea paniculata, Staphylea Bumald, Carex Thunbeigit, Carex curvicollisCarex dispalata, Scirpus triqueter, Scripus triangulatus, Osmunda cinnamomea, Impatieus noli-tangere, Senecio pierotii, Lythrum anceps, Iris setosa, Phragmites communis, Zizania latifolia, Typha latifolia, Sparganium stoloniferum, Scirpus lacustris L., Nuphar japonicum, Nelumbo nucifera, Acorus calamus L., Iris pseudoacorus L., Meryanthes trifoliata, Trapa natans, Nymphoides peltata, Nymphoides indica, Nymphaea tetragona, Potamogeton destinctus, Euryale ferox, Brasenia Scheberi, Hydrocharis Morsus-ranae, Potamogeton crispus, Potamogeton malaianus, Potamogeton octandrus, ophiopogon japonicum, Mynophyllum verticillatum, Ranunculus aquatilis, Najas marina, Vallisneria asiatica, Hydrilla verticilleta , Mimosa) in the concentration of 1-200 ppm, the growth of the phototrophic bacteria and the roots of rice was accelerated. The food chain in paddy fields was constructed strongly and microfauna distributed healthy. These environment foreshorten the cultivation period until harvest. The pH6.0-7.9 range of the reserved water in paddy fields is optimal. When pH of paddy field was in alkaline range, the water purificant of this invention should be prepared with addition of acids instead of bases or salts. 
     EXAMPLE 12 
     Generally, life transportation of prawns (Penaeus sp.) from eastern Asia to Japan was not actualized yet. 
     Formulated concentrate of the water purificant was prepared by mixing with 10% of bittern and 0.5% of mineral acids. The solution was diluted 1000-10000 folds and added to sawdust in which live and naked prawns were packed. The live transportation of prawns using the water purificant of this invention was successful. 
     In the case of additional spraying of boiled aquious extract or dried-up powder of water-front plants ( Salix subfragilis, Alnus japonica, Ulmus Davidiana, Acer palmatum thunb, Fraxinus mandshurica, Juglans mandshurica, Ilex serrato, Viburnum Opulus L., Hydrangea paniculata, Staphylea Bumald, Carex Thunbeigit, Carex curvicollis Carex dispalata, Scirpus triqueter, Scripus triangulatus, Osmunda cinnamomea, Impatieus noli-tangere, Senecio pierotii, Lythrum anceps, Iris setosa, Phragmites communis, Zizania latifolia, Typha latifolia, Sparganium stoloniferum, Scirpus lacustris L., Nuphar japonicum, Nelumbo nucifera, Acorus calamus L., Iris pseudoacorus L., Meryanthes trifoliata, Trapa natans, Nymphoides peltata, Nymphoides indica, Nymphaea tetragona, Potamogeton destinctus, Euryale ferox, Brasenia Scheberi, Hydrocharis Morsus-ranae, Potamogeton crispus, Potamogeton malaianus, Potamogeton octandrus, Ophiopogon japonicum, Mynophyllum verticillatum, Ranunculus aquatilis, Najas marina, Vallisneria asiatica, Hydrilla verticilleta , Mimosa) in the concentration of 1-200 ppm, the residual rate of life transportation of prawn (Peneaous sp.) was improved. 
     Formulated concentrate of the water purificant was prepared by mixing with 10% of bittern and 0.5% of mineral acids. The solution was diluted 1000-10000 folds, added to reservoir of living prawn for assimilation and then the residual rate (97%) of prawns was improved. Optimal pH range of life transportation in sawdust is pH6.2-7.8. The water purificant of this invention should be prepared with acids or bases in the range of pH 6.2-7.8. Addition of chitins, chitosans or their derivatives improved the residual rate of prawn also. 
     EXAMPLE 13 
     Formulated concentrate of the water purificant was prepared by mixing with 10% of bittern and 2% of mineral acids. The solution was diluted 1000-10000 folds, added to ponds or lakes contaminated with algae, organic matters, suspended soils, sludges and metal ions. After 1-3 hr, algae, organic matters, suspended soils, sludges and metal ions were coagulated and transparency of water improved from 5 cm to 70 cm. When yeast ( Saccharomyces carisbergensis, Saccharomyces cerevisiae, Zygosaccharomyces acidifaciens ) was added with the water pulificant of this invention to pond water, algae, organic matters, suspended soils, sludges and metal ions coagulated mildly and transparency of water was improved. Generally, yeast adsorbs anion. In pond water yeast can not proliferate without immobilization, so improvement of transparency is temporal. For continuous improvement of water quality, Actinomycetes ( Actinomyces longisporus, Actinomyces longissimus, Actinomyces thermoviolaceus, Dactinosporungium thailandense, Dactinosporungium aurantiacum, Streptomyces aureus, Thermoactinomyces vulgaris, Thermoactinomyces monospora, Micropolyspora thermovirida, Norcardia vaccinii ) should be added with the water purificant to the pond water. Minerals and yeast eliminate algae, organic matters, suspended soils, sludges and metal ions with coagulation and then growth of Actinomycetes constract food chain in pond water continuously. For continuous food chain formation, aeration and immobilization of microorganisms such as Actinomycetes are effective.
