一株猪源乳酸杆菌的分离鉴定及其微胶囊化研究

Isolation and Identification of Lactobacillus from Swine and Study on its Microencapsulation

乳酸杆菌是目前应用的微生态制剂中最重要的有益菌组成成分之一。本研究从健康猪小肠中分离了1株耐酸和耐胆盐能力较强的乳酸杆菌,命名为乳酸杆菌L5株。进一步地,通过微胶囊化研究,提高了其耐贮存性以及在模拟胃肠液中的存活率。

Lactobacillus is the most important one of the beneficial bacterium component in the current application probiotics.In this study,one Lactobacillus strain which displayed stronger acid and bile salts resistance was isolated and named Lactobacillus strain L5.In addition,the storage stablity and the survival rate in artificial gastric and intestinal succus of the isolated strain were enhanced by microencapsulation.
