Given the colony characteristics on the blood plate and the morphology and Gram stain reaction, the next most useful test you would perform to confirm your suspicions would be A. OPTOCHIN DISC SUSC EPTIBILITY (\"p\") DISC B. BILE ESCULIN SUSCEPTIBILITY C. COAGULASE TEST D. CATALASE TEST E. OXIDASE TEST

Solution

Catalase test-The inability of the strict anaerobes to synthesize catalase, peroxidase, superoxide dismutase may explain why oxygennis poisonous to these microorganisms. In the absence of these enzymes the toxic concentration of H2O2 cannot be degraded when the organisms are cultivated in the presence of oxygen.
