Factors affecting production of catalase by Bacteroides.

Several variables affected the production of catalase by members of the "Bacteroides fragilis group" of anaerobic bacteria. Both media yielded higher catalase levels than the respective agar media. Addition of hemin to media after autoclave sterilization, rather than before, significantly increased production of catalase. Both of these variables could be related to the available hemin concentr...
