L-Lactate fermentation of organic wastes by Bacillus coagulans for utilization as livestock feed

利用有机废弃物进行L-乳酸的高温发酵。目的是通过发酵乳酸来保持饲料质量，并通过发酵中的部分水解来加速饲料消化。6%的乳酸可防止消耗乳酸的细菌的增殖;该浓度可能是发酵产品质量保持的指示。嗜热L-乳酸发酵部分水解大豆和麻风树蛋白。发酵可能提供容易消化和吸收像纳豆的效果。PCR-DGGE分析表明，以凝结芽孢杆菌为接种物，在厨余垃圾发酵过程中检测到了包括乳酸菌在内的细菌。检测到的细菌的危害评估将是下一个挑战。

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.
