Method for sterilizing domestic animal litter by microorganism
This invention relates to a sterilization agent for livestock bedding or a composting accelerator for organic waste or livestock bedding, comprising at least one Bacillus coagulans thermophilic bacterium or a combination of the at least one Bacillus coagulans thermophilic bacterium and at least one Bacillus subtilis mesophilic bacterium, as an active ingredient, wherein the Bacillus coagulans thermophilic bacterium as a preferable bacterium is viable at a temperature of 40 to 60° C. and the Bacillus subtilis mesophilic bacterium is viable at a temperature of 30 to 50° C., and the mesophilic bacterium also has a sterilizing effect on harmful bacteria in bedding; and to a method for sterilizing livestock bedding or a method for accelerating composting of organic waste or livestock bedding by using these agents each as an active ingredient.
1. A method for sterilizing livestock bedding, comprising a step of aerobically fermenting the bedding by adding at least one Bacillus coagulans thermophilic bacterium, or a combination of the at least one Bacillus coagulans thermophilic bacterium and at least one Bacillus subtilis mesophilic bacterium, to the livestock bedding, wherein the Bacillus coagulans thermophilic bacterium is selected from the group consisting of Bacillus coagulans CP3424 strain (International Deposition Accession No. NITE BP-01692), and Bacillus coagulans CP3425 strain (International Deposition Accession No. NITE BP-01693).
2. The method according to claim 1 , wherein the Bacillus coagulans thermophilic bacterium is viable at a temperature of at least 40 to 60° C.
3. The method according to claim 1 , wherein the Bacillus subtilis mesophilic bacterium is viable at a temperature of at least 30 to 50° C.
4. The method according to claim 1 , using only fermentation heat of a microorganism.
5. The method according to claim 1 , wherein the Bacillus subtilis mesophilic bacterium is Bacillus subtilis C-3102 strain (International Deposition Accession No. FERM BP-1096).
6. The method according to claim 1 , wherein the Bacillus coagulans thermophilic bacterium is Bacillus coagulans CP3425 strain (International Deposition Accession No. NITE BP-01693), and the Bacillus subtilis mesophilic bacterium is Bacillus subtilis C-3102 strain (International Deposition Accession No. FERM BP-1096).
