  1. Hullo, on Triple Sugar Iron Agar (TSI), the results depicting (A/A), can this be interpreted as both the butt and the slant are ACID or ALKALINE, which is which? Thanks.

    • Catalase and oxidase are two different, unrelated enzymes. Catalase is an enzyme that protects from oxidative damage. Oxidase is found in bacteria that can use oxygen (facultative and obligate aerobes.)
