A resting cell culture system that supported the enzyme synthesis but not the growth was established to investigate the factors regulating biosynthesis of glucose oxidase and catalase by Aspergillus niger Various culture conditions have been optimized The optimal pH of the biosynthesis of glucose oxidase and catalase was 6 0 and 5 7 respectively Calcium carbonate was an inducer of the biosynthesis of the enzymes The biosynthesis of glucose oxidase and catalase can be promoted by SHCH 2COOH
