AI Technical Summary
Technical Problem
When probiotics enter the stomach, they lose their activity due to the bile and gastric acid environment, and cannot effectively inhibit Helicobacter pylori, leading to gastric flora imbalance and increasing the risk of metachronous gastric cancer.
Method used
Bifidobacterium animalis subspecies B189 was used, which has acid and bile resistance, to develop a probiotic preparation that inhibits Helicobacter pylori.
Benefits of technology
Bifidobacterium animalis subspecies B189 remains active under extreme conditions, significantly inhibits the growth of Helicobacter pylori, improves gastric flora imbalance, and reduces the risk of gastric cancer.
