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

Indole Test Protocol
asm.orgDissolve components and store solution at room temperature in a brown glass bottle. To test for indole production, inoculate a 4 -ml tryptone broth tube with one loopful of culture. After 24 to 48 hours of incubation, add to the culture 1.0 ml of either ether or xylene. Mix well and then allow organic solvent to rise to the top of the medium.
Blood Agar Plates and Hemolysis Protocols
asm.org"Blood Agar" is not a consistently defined medium. The term "blood agar" generally refers to an enriched base medium to which defibrinated mammalian blood has been added. In the US "blood agar" is usually prepared from Tryptic Soy Agar or Columbia Agar base with 5% Sheep blood. Rabbit or horse blood may be
