(WO9619420-A1)      Fermentation prod. comprises a reaction prod. of solid-liq.-mixed perishable waste with an additive agent comprising a highly active Ca oxide, and contains microorganisms living in a highly alkaline environment with a pH of at least 12, which comprise three gps. of bacteria. Gp 1 bacteria proliferate at pH of at least 11 and under 12, gp. 2 bacterial grow at a pH 11-9. Gp. 3 bacteria grow at upto pH 9. The prod. also comprises moulds and the microorganism 90-A-1., and is maintained at pH 8 with proliferation of the microorganisms.    Also claimed is the prodn. of the fermentation prod. by adding an additive agent comprising a highly active quick lime to a perishable waste, to effect rapid hydration, allowing the reaction prod., which is pref. in a highly alkaline state with a pH of 12-13, to stop decomposing by the reaction heat of the hydration and alkaline sterilisation due to the highly alkaline environment, and leaving in the reaction prod. the microorganisms comprising bacteria of gps. 1, 2 and 3, the moulds and the microorganism 90-A-1 that are detectable, in a tolerant state, and capable of growing in highly alkaline conditions, and supplying water and air to lower the pH and allowing the moulds and 90-A-1 to proliferate with the decrease of pH, and allowing the reaction prod. to effect alkaline fermentation by proliferation of the microorganisms.    USE/ADVANTAGE -   The fermentation prod. is useful as a disease-preventive or -controlling material in agriculture. The prodn. of the fermentation prod. converts perishable wastes under highly alkaline conditions to materials equiv. to compost simply, at low cost and in a short period. The reaction prod. has high water-permeability, water-holding property and slow fertilising action.    In an example, highly active calcium oxide (10 kg) was added to swine excreta (100 kg). The mixt. was then mix-stirred in a reactor for 15 minutes. A slurry form- reaction prod. (110 kg, pH 12.6, EC 6.9) was obtd.. The prod. was then dried in a drying room at 30 deg.C. to remove 30% of water, then stored for 50 days and then thrown in a fermenter. In 72 hrs. fermentation prod. (40 kg, pH 7.78, EC 2.62) was obtd. (Ca cpd. 15 kg dry wt., fermented organic matter and other inorganic matters 12 kg dry wt.).
