, a probiotic, has a high survival rate and high colonization ability in the gastrointestinal tract. Tolerance to the gastrointestinal environment and adhesion to intestinal epithelial cells by some species (excluding ) are related to /AI-2. Here, the role of in tolerance to simulated digestive juice (SDJ) and adhesion to Caco-2 cells by KLDS1.0391 (hereafter, KLDS1.0391) was investigated. The KLDS1.0391 mutant strain was constructed by homologous recombination. When was deleted, acid and bile salt tolerance and survival rates in SDJ significantly decreased ( < 0.05 for all). The ability of the deletion strain to adhere to Caco-2 cells was markedly lower than that of the wild-type strain ( < 0.05). The ability of the mutant strain to adhere (competition, exclusion, and displacement) to ATCC 25922 was significantly lower than that of the wild-type strain ( < 0.05 for all). A significant decrease was noted only in the exclusion adhesion inhibition of the mutant strain to ATCC 14028 ( < 0.05). These results indicate that the gene plays an important role in the gastrointestinal environment tolerance and adhesion ability of KLDS1.0391.
