Catalase: its effect on microbial enumeration.
MedLine Citation:
PMID:  825045     Owner:  NLM     Status:  MEDLINE    
The addition of catalase to the surface of selective medium plates permitted increased enumeration of physically or chemically injured (stressed) microorganisms. Catalase acted by preventing the accumulation of hydrogen peroxide in, or around, injured cells. Heat-injured Staphylococcus aureus cells had decreased catalase activity, and heat-inactivated catalase had no effect on enumeration.
