title: Carbohydrate repression of catalase synthesis in Bacteroides fragilis.
abstract: Catalase formation by Bacteroides fragilis was immediately stopped upon addition of glucose to a culture growing in peptone medium. Each of eight other carbohydrates fermented by the organism also repressed catalase formation. Without added carbohydrate, the strains produced relatively large amounts of catalase (25 to 50 U/mg of protein).
