本研究的目的是分离，从pulque，乳杆菌属。能够在模拟胃肠道应激条件下存活。分离出9个革兰氏阳性杆菌;然而，只有一个菌株（J57）与乳杆菌属共享同一性，并登记为干酪乳杆菌J57（GenBank登录号：JN 182264）。其他菌株经鉴定为芽孢杆菌属（Bacillus spp.）在对模拟胃肠道条件（酸度、胃液和胆汁盐）的耐受性试验中，最显著的观察结果是L。casei J57则呈快速下降（p
The aim of this study was to isolate, from pulque, Lactobacillus spp. capable of survival in simulated gastrointestinal stress conditions. Nine Gram-positive rods were isolated; however, only one strain (J57) shared identity with Lactobacillus and was registered as Lactobacillus casei J57 (GenBank accession: JN182264). The other strains were identified as Bacillus spp. The most significant observation during the test of tolerance to simulated gastrointestinal conditions (acidity, gastric juice and bile salts) was that L. casei J57 showed a rapid decrease (p
