Abstract

To study the adhesion mechanism of Lactobacillus acidophilus in the gut and the relationship of between adhesion mechanism with sortase and sortase dependent proteins genes. In vitro,the adherence was evaluated.Meanwhile,the srt gene and related genes expression were determinate under different p H.The results showed that the gene expression levels of srt and related proteins increased significantly with the range of p H from 5.5 to 7.5.Also,the adhesiveness of Lactobacillus acidophilus was also enhanced.It revealed some mechanisms of adhesion ability in Lactobacillus acidophilus upon different p H values.
