摘要
通过对酸奶发酵菌株保加利亚乳杆菌(Lb)和嗜热链球菌(St)在培养基中的活菌数、OD值及pH的研究,得出两菌最适收获期分别是16h、14h;两菌1∶1混合接种发酵效果优于单株发酵且在脱脂乳培养基中活茵数达到8.5×108cfu/g。
In this paper, the viable cells number and OD and pH were studied to get the optimum harvesting period of fermentation. The results showed that the were 16 hour and 14 hour, St and Lb 1 ： 1 mixed was better than single fermentation and the viable bacteria counts in skimmed milk could reach 8.5×10^8cfu/g.
