YH-BSH

Bilesalthydrolase (BSH), responsible for hydrolysis in combination with bile salts to produce free bile acids and amino acids. BSH activity in gastrointestinal tract was mainly from Firmicutes (30%), Bacteroidetes (14.4%) and actinobacteria (8.9%). Impaired microbial enzyme activity in IBD patients leads to impaired bile acid metabolism, characterized by the inability to hydrolyze, transform, and desulphurize bile salts. Microbial BSH activity removes glycine or taurine molecular coupling to produce unbound bile acids. Abnormal intestinal bile salt metabolism enhances the inflammatory response of the intestinal epithelium, which worsens IBD. It has been documented that the ingestion of probiotics with BSH activity can promote the bioconversion of intestinal bile salts, thereby alleviating the inflammatory response induced by high doses of intestinal bile salts. Therefore, we selected heterologous expression of BSH gene from Lactobacillus acidophilus.
