TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Formulation: (C1) comprises B. thuringiensis FERM P-19220, FERM P-19221, or FERM P-18014, B. subtilis FERM P-19222, or FERM P-18015, and B. megaterium IBTU-1 (FERM P-20160).Preferred Method: (M1) involves adding (C1) to cattle feces, and fermenting by adding ammonia source. EXAMPLE - Preparation of microbial composition and decomposition and processing of cattle feces was carried out as follows. Each microbial strain chosen from Bacillus thuringiensis FERM P-19220, FERM P-19221, or FERM P-18014, B. subtilis FERM P-19222, or FERM P-18015, and B. megaterium IBTU-1 (FERM P-20160) was separately cultured for ten days, with the liquid medium (2.5 l) comprising nutrient broth glucose. Culture solution was centrifuged, and microbial cells were collected and each microbe strain was mixed with 600 ml of water, 200 ml of rapeseed oil, and peptone (50 g) and 10 l of buckwheat husks, and the obtained solution was added to container of expanded polystyrene, and cultured for three days at 20 degreesC aerobically, to obtain the microorganisms formulation. The microorganisms formulation was mixed with the equivalent amount of buckwheat husk, and was made into spawn. Twenty l of cattle feces (85% of moisture content), mixture of 6 l of spawn, 800 ml of edible oils, and 50 ml of 20% ammonium chloride solution or 30 g peptone was added to the container made from expanded polystyrene, and was mixed. About 1 cm gap was made between the lid and the container and was neglected to the outdoors. On day second to day six the internal fermentation temperature was 58-68 degreesC, and was allowed to ferment. While the viscous substance had been unfermented, had deposited on the bottom part. The whole container was stirred once on the second day. The temperature on the seventh day was 28-38 degreesC. Then, 400 ml of waste edible oils and 20 ml of 20% ammonium chloride solution was added and neglected. The internal fermentation temperature was raised to 55-58 degreesC at 8-10 days. The viscous substance deposited on the bottom of the container was disappeared. The internal temperature was 25-35 degreesC on eleventh day. The fermentation was completed. The moisture content of the compost at the fermentation was 56%. When ammonium chloride was used the fermentation period was slightly long, and the maximum temperature was slightly low. The viscous substance was not seen after fermentation. Germination of weeds was not seen. The temperature was maintained near 20-30 degreesC for three days after the twelfth day. Generation of bad smell was not sensed.
