摘要
乳酸杆菌在进行冷冻和冷冻干燥处理时存活率较低,在培养乳酸杆菌的培养基中添加某种保护剂,增加乳酸杆菌对冷冻和冷冻干燥处理的耐性,提高其保存期的存活率.
The survival rale of Lactobacillus treated with lyophilization was generally low. Adding a protective agent in the culure medium of Lactobacillus can stengthen its tolerance to the lyophilization treatment and heighten the survival rate of the preserved culture.
