【Abstract】 Through comparative experiments, the concentration of each ingredient in the resting cell medium was determined, and their influences on the synthesis and secretion of gentamicin(GM) were also discussed. Some factors affecting gentamicin biosynthesis were studied by using this system. The results showed that the biosynthesis of GM was promoted when the temperature was controlled at 34°C and some secondary metabolites, 50mg/L MnSO 4 or 0.02mL Tween20 per liter were supplemented.更多还原
