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).
摘要
在向蛋白胨培养基中生长的脆弱拟杆菌培养物中添加葡萄糖后，过氧化氢酶的形成立即停止。该生物体发酵的其他八种碳水化合物中的每一种也抑制了过氧化氢酶的形成。在不添加碳水化合物的情况下，这些菌株产生相对大量的过氧化氢酶（25至50单位/毫克蛋白质）。
