| Research Abstract |
Thermophilic L-lactic acid fermentation was conducted to utilize organic wastes as livestock feed. The aims are to preserve feed quality by fermented lactic acid and to accelerate feed digestion by partial hydrolysis in the fermentation. 6% of lactic acid prevented proliferation of bacteria consuming lactic acid; this concentration might be an indication for quality preservation of the fermented products. Thermophilic L-lactic acid fermentation partially hydrolyzed soy bean and jatropha proteins. The fermentation might provide easy digestion and absorption like natto's effect. PCR-DGGE analysis of the fermentation of kitchen wastes indicated that Bacillus coagulans as inoculum and some bacteria including lactic acid bacteria were detected. Hazard assessment of detected bacteria will be next challenges.
