泡菜中乳酸菌的分离鉴定及体外抗性筛选
Isolation and identification of lactic acid bacteria from fermented vegetables and in vitro resistance screening
摘要
Abstract
This study aimed to isolate lactic acid bacteria containing in vitro resistance ability from Sichuan fermented vegetables.Five strains of Lactobacillus were isolated from fermented vegetables and analyzed by 16S rDNA.Four strains of them were Lactobacillus plantarum,named as E-6-1,E-1-2,E-6-3,D-2-3 respectively,and another one was Lactobacillus alimentarius,named as C-2-1.The in vitro resistance of the 5 strains was determined by artificial gastric juice and bile salt.The results showed that the lactic acid bacteria numbered D-2-3 had good anti-artificial gastric juice ability,and the survival rate was 95.38% after 3 h of artificial gastric juice treatment at pH 3.0,growing well at 1,2 and 3 g/L bile salt.These showed that the strain has probiotic potential,through further verification was expected to carry out further development and utilization.关键词
