本试验旨在选出最佳单一菌株且确定其混合菌比例和发酵路线,再运用正交试验对混合菌固态发酵红薯渣工艺进行条件优化,以达到提高产物粗蛋白质含量的目的。首先采用4株酵母菌,4株黑曲霉菌,5株枯草芽孢杆菌,1株乳酸菌,在相同发酵条件下固态发酵红薯渣,以产物粗蛋白质含量为主要衡量目标,进行单一菌株的筛选;再利用筛选出的4株最佳单菌进行发酵路线选择;最后对选出的发酵工艺以发酵时间、发酵温度、氮源添加量和菌液接种量4个因素为变量进行L_(16)(4~4)正交试验,通过测定产物粗蛋白质含量,确定最佳发酵条件。结果表明,产朊假丝酵母、黑曲霉41126、枯草芽孢杆菌Y111、乳酸菌为最佳单一菌株;混合菌比...

This experiment was conducted to select the best single strain and their mixed proportion and fermentation route,then adopted orthogonal experiment optimized conditions of sweet potato residue by mixed bacteria solid-state fermentation,to improve the content of crude protein of the product. Firstly,adopted four strains of yeast,four strains of Aspergillus,five strains of Bacillus subtilis and one strain of Lactobacillus were under the same fermentation condition and the content of crude protein of products was the measure indicator for single s...
