The microbiological method for disposing of an organic waste material comprises the step of bringing (i) an organic waste material into contact with (ii) at least 5 species of microorganisms, each being selected from each of 5 groups consisting of actinomycetes, phototrophic bacteria, lactic acid bacteria, mold fungi and yeast, the microorganisms (a) being acid-fast, (b) capable of producing lactic acid, (c) producing no butyric acid, (d) being non-pathogenic and (e) having an antagonistic value of 50 or more. ## Claims ### Claim 1 A liquid waste composition obtained by a method of microbiologically degrading an organic waste material comprising a. adjusting the pH of the waste material to 3.0 to 5.0 with an organic acid; b. incubating the organic waste material with at least one member of actinomycetes, one member of phototropic bacteria, one member of lactic acid bacteria, one member of mold fungi and one member of yeast, the at least one member of actinomycetes selected from Streptomyces albus, Streptoverticilliu baldaccii, Nocardia asteroides, Micromonospora chalcea or Rhodoccus rhodochrous; the at least one member of phototrophic bacteria selected from Rhodopseudomonas sphaeroides, Rhodospirillum rubrum, Chromatium okenii, or Chlorobium limicola; the at least one member of lactic acid bacteria selected from the group Lactobacillus bulgaricus, Propionibacterium freudenreichii, Pediococcus halophilus, Streptococcus lactis or Streptococcus faecalis; and the at least one member of mold fungi selected from Aspergillus japonicus, Aspergillus oryzae or Mucor hiemalis; and the at least one member of yeast selected from the group Saccharomyces cerevisiae, Saccharomyces lactis or Candia utili and incubating said microorganisms with the organic waste material under airtight conditions at a temperature of 45.degree. C. or less, and under conditions sufficient to degrade the organic waste material wherein the organic waste material is selected from the group consisting of liquid wastes discharged in the process of alcohol production, garbage produced by households or eating establishments, wastes produced in the processing of agricultural or marine products, excrements of domestic animals and sewage. ### Claim 2 (depends on 1) The composition according to claim 1 wherein in the method of preparing the composition the incubation is carried out at a temperature from 25.degree. C.-45.degree. C. ### Claim 3 (depends on 1) The composition according to claim 1 wherein in the method of preparing the composition the microorganisms are incubated with the organic waste material for about 72 to 96 hours. ### Claim 4 (depends on 1) A liquid waste composition according to claim 1, wherein the organic waste material is a liquid waste discharged in the process of alcohol production. ### Claim 5 (depends on 1) A composition for accelerating the growth of plants, comprising the liquid waste composition according to claim 1 as an active ingredient together with a carrier. ### Claim 6 (depends on 1) A composition for improving the soil, comprising the liquid waste composition according to claim 1 as an active ingredient together with a carrier. ### Claim 7 (depends on 1) A composition for destroying or repelling insect pests, comprising the liquid waste composition according to claim 1 as an active ingredient together with a carrier. ### Claim 8 (depends on 1) A composition for deodorizing an unpleasant odor, comprising the liquid waste composition according to claim 1 as an active ingredient together with a carrier. ### Claim 9 (depends on 1) A composition for improving water quality, comprising the liquid waste composition according to claim 1 as an active ingredient together with a carrier.
