Summary:Objective: The study aimed to investigate the effects of Periplaneta americana glycoprotein (PAG) on the growth and metabolites of Lactobacillus plantarum and Bifidobacterium adolescentis. Methods: With inulin as a positive control, the probiotic bacteria were cultured in medium containing different concentrations of PAG (MRS medium with PAG concentrations of 0.5, 1.0, 2.0, and 4.0 mg/mL, respectively. TPY medium with PAG concentrations of 1.0, 2.0, 4.0, and 8.0 mg/mL, respectively) to determine the OD600 and pH, and the contents of lactic acid, short-chain fatty acid (SCFA, snamely acetic acid, propionic acid and butyric acid) in the bacterial solution. Results: The growth of Lactobacillus plantarum was greatest when the concentration of PAG reached 1.0 mg/mL, while Bifidobacterium adolescentis grew best with a PAG concentration of 2.0 mg/mL. The OD600 value, production of lactic acid and SCFAs of Lactobacillus plantarum solution at 1.0 mg/mL PAG were higher than those of inulin, while the pH value was signi
