【摘要】：文章旨在介绍一种高水解度豆粕蛋白饲料的制备过程。高蛋白质水解度的豆粕发酵饲料是消除豆粕中蛋白质类抗营养因子和提高蛋白质利用率的重要基础,但不同微生物对豆粕蛋白质有不同的水解能力,且单菌发酵能力普遍较低,多菌种分段固态发酵是一种提高豆粕蛋白质水解度的可行策略。研究结果显示,用枯草芽孢杆菌F-11-06进行前期发酵(33℃、69 h),然后用黑曲霉F-11-08和酵母菌F-11-12进行后期发酵(25℃、28 h),可将豆粕蛋白质的水解度提高到22.3%,其分别是单纯枯草芽孢杆菌F-11-06(60 h、33℃)发酵的6.8倍,黑曲霉F-11-08和酵母菌F-11-12(60 h、25℃)发酵的3.3倍,达到了高蛋白质水解度豆粕饲料制备的目的。
[Abstract]:The purpose of this paper is to introduce the preparation process of high hydrolysis soybean meal protein feed. Soybean meal fermentation feed with high degree of protein hydrolysis is an important basis for eliminating protein anti-nutritional factors and improving protein utilization rate, but different microorganisms have different hydrolysis ability to soybean meal protein, and the fermentation ability of single bacteria is generally low. Multi-strain solid-state fermentation is a feasible strategy to improve the degree of protein hydrolysis of soybean meal. The results of the study show that Using Bacillus subtilis F-11-06 to ferment at 33 鈩，
