Breeding of Bacteria Functioning to Produce Feed Proteins by the Use of Distillers'' Grains
利用酒糟生产饲料蛋白的菌种选育

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%.
