Sep 27, 2018 Oxidase Test Principle, Uses, Procedure, Types, Result Interpretation, Examples and Limitations. The dye is reduced to deep purple color. This test is used to assist in the identification of Pseudomonas, Neisseria, Alcaligens, Aeromonas, Campylobacter, Vibrio, Brucella and Pasteurella, all of which produce the enzyme cytochrome oxidase.Sep 26, 2018 I got the HI MEDIA Biochemical test results as follows: Citrate test ve, Lysine ve, Ornithine ve, Urease ve, Phenylalanine deamination ve, Nitrate reduction ve, H2S Production ve, Glucose ve, Adonitolve, Lactose ve, Arabinose ve, Sorbitolve. I am unable to identify which Pseudomonas Spp. it is. Can you please help me in identifying the Pseudomonas Spp. oxidase test result for pseudomonas

While some species show a negative reaction in the oxidase test, most species, including P. fluorescens, give a positive result (see Figure 2). Another feature associated with Pseudomonas is the secretion of pyoverdin (fluorescein, a siderophore), a fluorescent yellowgreen pigment under ironlimiting conditions.

Oxidase test Objective: to check for presence of terminal enzyme Cytochrome C oxidase or Cytochrome a3. Principle of oxidase test: Oxidase is a terminal enzyme in aerobic respiration. The aerobic respiration mechanism is composed of a number of enzymes which alternatively oxidize and reduce each other by donating or acceptingRead More pseudomonas, oxidase test, tests for identification of p. aeruginosa, oxioxidase test result for pseudomonas The oxidase test is used to identify bacteria that produce cytochrome c oxidase, an enzyme of the bacterial electron transport chain. When present, the cytochrome c oxidase oxidizes the reagent to (indophenols) purple color end product. When the enzyme is not present, the reagent remains reduced and is colorless.
