摘要： 试验根据豆粕、菜粕和棉粕作为植物性蛋白饲料的营养特性,选择中性蛋白酶活较高的细菌和真菌作为发酵豆粕、菜粕和棉粕的菌种以改善豆粕、菜粕和棉粕的蛋白质品质。通过细菌和真菌的两两组合生长试验,分别筛选出适合发酵豆粕、菜粕和棉粕的最佳复合菌各一组。试验结果表明,发酵豆粕、菜粕和棉粕的最佳菌株组合为BS-2和Ao、BS-natto和Ao、BS-natto和Ao。

Abstract: Based on nutrition characters on soybean meal, rapeseed meal and cotton seed meal, high neutral enzyme production of bacteria and fungus were chose to inoculate in them to improve their protein quality as animal feed. Compounded one bacterium strain and one fungus strain cultured together, chose the best group to ferment the soybean meal, rapeseed meal and cotton seed meal. The results showed the best groups were BS-2 and Ao for soybean meal, BS-natto and Ao for rapeseed meal, and BS-natto and Ao for cotton seed meal.

Key words: solid fermentation; neutral enzyme; complex fermentation
