Streptomyces sp. No. 101,Thermoactinomyces sp. No. 64 and Micromonospora sp. No. 604 were selected as excellent strains which characteristically decomposed residual yeast cells and indigestible rice protein bodies (IRPB) in cereal shochu-distillery wastes, and also deodorized volatile fatty acids without sterilization. The optimal initial conditions for composting were determined to be 5〜9×10^4 ppm BOD, 38〜55% moisture, 30〜65℃ material temperature, 25〜50 cm thickness of composting materials, and pH8. For semi-continuous composting of wastes, 100 kg seed cultures of selected Actinomycetes strains containing cow feces as a composting accelerator was mixed with 40l of cereal shochu-distillery wastes and composted at 30〜65℃ for 3d, which constituted 1 cycle. The process was repeated for 5 cycles to produce compost. The compost obtained contained total-N 3.2%, CaO 9.3%, P_2O_5 5.4% and K_2O 3.5%.
