Oxidase Test Protocol
chain. The final step in the chain may involve the use of the enzyme cytochrome oxidase, which catalyzes the oxidation of cytochrome c while reducing oxygen to form water (10). The oxidase test often uses a reagent, tetra-methyl-p-phenylenediamine dihydrochloride, as an artificial electron donor for cytochrome c (1, 2, 15). When the reagent is

Catalase Test Protocol - American Society for Microbiology
asm.orgThe catalase test is also valuable in differentiating aerobic and obligate anaerobic bacteria, as anaerobes are generally known to lack the enzyme (8, 9). In this context, the catalase test is valuable in differentiating aerotolerant strains of Clostridium, which are catalase negative, fromBacillus, which are catalase positive (8). Theory
