The oxidase test indicates whether a microbe is aerobic. By using the chemical N,N,N,N-tetramethyl-1,4-phenylendiamin , an electron acceptor that changes color when oxidized by cytochrome c oxidase , one can deduce whether a microbe can perform aerobic respiration.
It tests positive for the oxidase test, and is also a nonsaccharolytic bacterial species. Heat-stable lipases and proteases are produced by P. fluorescens and other similar pseudomonads. [4] These enzymes cause milk to spoil, by causing bitterness, casein breakdown, and ropiness due to production of slime and coagulation of proteins. [5] [6]
In microbiology, the oxidase test is used as a phenotypic characteristic for the identification of bacterial strains; it determines whether a given bacterium produces cytochrome oxidases (and therefore utilizes oxygen with an electron transfer chain). The test is used to determine whether a bacterium is an aerobe or anaerobe. However a ...
E. meningoseptica is positive by the catalase test, the oxidase test, and the indole test. It is negative by the urease test. In general, it is negative by the nitrate reductase test, although some strains are positive. [6] E. meningoseptica grows well on blood agar and chocolate agar. Colonies are very pale yellow and may not be easily evident ...
Mixed-function oxidase is the name of a family of oxidase enzymes that catalyze a reaction in which each of the two atoms of oxygen in O 2 is used for a different function in the reaction. [ 1 ] Oxidase is a general name for enzymes that catalyze oxidations in which molecular oxygen is the electron acceptor but oxygen atoms do not appear in the ...
Klebsiella aerogenes, [2] previously known as Enterobacter aerogenes, is a Gram-negative, oxidase-negative, catalase-positive, citrate-positive, indole-negative, rod-shaped bacterium. [3] Capable of motility via peritrichous flagella, [4] it is approximately one to three microns in length.
Burkholderia pseudomallei [a] (also known as Pseudomonas pseudomallei) is a Gram-negative, bipolar, aerobic, motile rod-shaped bacterium. [2] It is a soil-dwelling bacterium endemic in tropical and subtropical regions worldwide, particularly in Thailand and northern Australia. [3]
