In this study, 11 lactic acid bacteria (LAB) strains were screened for potential new probiotics using in vitro
methods, including acid and bile salt tolerance, adhesion, antioxidative and a-glucosidase inhibitory
activity. The results indicated that Lactobacillus casei 2W and Lactobacillus rhamnosus Z7 showed better
potential probiotic properties and a-glucosidase inhibitory activity in vitro. The characteristics of L. casei
2W were better than those of L. rhamnosus GG, and L. rhamnosus Z7 was the most similar strain to L.
rhamnosus GG, which had an antidiabetic capability. This finding suggested that L. casei 2W and L.
rhamnosus Z7 could be used as potential antidiabetic probiotics. Further research is required to examine
the a-glucosidase inhibitory activity of these strains.
