结果表明,从发酵剂中分离到三株菌。其中一株鉴定为德氏乳杆菌保加利亚亚种,两株为嗜热链球菌。
The result of the experiment showed: three bacteria strains from the Culture were isolated, where one was Lactobacillus bulgaricus and the others were Streptococcus thermophilus.
本实验在选育高产菌株及优化培养基的基础上,通过探索德氏乳杆菌的发酵工艺提高其乳酸产量。
This experimental work was primarily on the fermentation techniques of lactic acid, trying to enhance the production of lactic acid by mutation of the strain and optimization of the culture medium.
实验结果为,黑曲霉、绿色木霉、枯草芽孢杆菌、德氏乳杆菌、酵母菌固体菌剂的添加比例为1:1:2:2:2,青贮复合菌剂的添加量为0.20%,尿素添加量为0.50%,发酵周期30天。
