Question
Chapter 5, Problem 30E.5RQ
Summary Introduction
To explain: The biochemical test used to identify the Gram-negative bacteria present in an unknown culture.
Introduction: Oxidase test is widely used in the laboratories to identify the presence of an enzyme called cytochrome oxidase. This enzyme catalyzes the transport of electrons between electron donors and a redox dye (tetramethyl-p-phenylene-diamine). Later, the dye is reduced to deep purple color. Oxidase test is used to identify microbes that able to form an enzyme cytochrome oxidase.
