摘    要:为了提高酒糟蛋白质的含量和粗纤维的降解,本研究选菌种30株,以白酒糟为原料筛选出优质饲料蛋白菌株8502,8503和8505三株。用微生物液体发酵法,经研究发现,以8503和8505组成的多菌发酵体系,使酒糟初始蛋白含量由23.0%。

关 键 词:酒糟  废料再利用  菌种选育  饲料蛋白  菌体蛋白  协同发酵  微生物饲料  饲料蛋白

Abstract:High quality bacteria 8502, 8503 and 8505 were selectively bred. The study shows that the efficiencies to turn the distillers' grains into feed with rich protein by multiple bacteria synergistic fermentation are higher than those by single bacteria fermetation. Under definite experimental conditions, the efficiencies of multiple bacteria synergistic fermentation system are 7.3% higher than those of single bacteria fermentation system from 30.2% up to 37.5%, and the content of fiber is almost at the same level, about 2%.The distillers' grains have undergone fermentation for 5 days in the multiple bacteria synergistic fermentation system composed by 8503 and 8505. The protein raises from 23.0% of original wastes of distillers' grains up to 37 5%, 14 5% higher than that in original wasters, and the content of fiber is 2.2% less than original wastes, from 16.3% down to 14.1%.
Keywords:distillers' grains  reuse of distillers' grains  breeding of bacteria  synergistic fermentation  microbial feed  feed protein
