Question
Chapter 5, Problem 28E.4RQ
Summary Introduction
To account: The ability of Streptococci to tolerate oxygen in the absence of catalase activity.
Introduction: Catalase is an enzyme that is usually present in all organisms (bacteria, plants, and animals) that are exposed to oxygen. Catalase enzyme is able to neutralize the toxic hydrogen peroxidase as well as superoxide, which is produced during the aerobic respiration pathway. Catalase is majorly produced by aerobic, facultative anaerobes, and microaerophiles.
