Organisms resistant to gastric acid
WitrynaThe production of gastric acid in the stomach is tightly regulated by positive regulators and negative feedback mechanisms. Four types of cells are involved in this process: parietal cells, G cells, D cells and enterochromaffine-like cells. WitrynaIn these studies, L. plantarum and Lactobacillus jensenii were found to be more resistant to stomach conditions like low pH. Lactobacillus strains from Koozeh cheese were exposed to low pH (pH 2.0 and 3.0) conditions of the stomach for 3 h. Results indicated the strong inhibition on the viable bacteria numbers at pH 2 and 3.
