Pseudomonas species also typically give a positive result to the oxidase test, the absence of gas formation from glucose, glucose is oxidised in oxidation/fermentation test using Hugh and Leifson O/F test, beta hemolytic (on blood agar), indole negative, methyl red negative, Voges–Proskauer test negative, and citrate positive.

Pseudomonas aeruginosa is a common encapsulated, Gram-negative, aerobic ... It is citrate, catalase, and oxidase positive. It is found in soil, water, ...
Pseudomonas simiae is a Gram-negative, catalase- and oxidase-positive, rod-shaped bacterium isolated from monkeys (Callithrix geoffroyi). [1]
Oxidase positive – due to the presence of the enzyme cytochrome c oxidase. Nonfermentative; Many metabolise glucose by the Entner Doudoroff pathway mediated by 6-phosphoglyceraldehyde dehydrogenase and aldolase; Polar flagella, enabling motility; Many members produce derivatives of the fluorescent pigment pyoverdin [6]
Pseudomonas alliicola (Burkholder 1942) Starr and Burkholder 1942 Burkholderia gladioli is a species of aerobic gram-negative rod-shaped bacteria [ 1 ] that causes disease in both humans and plants. It can also live in symbiosis with plants and fungi [ 2 ] and is found in soil, water, the rhizosphere, and in the microbiome of many animals.
The Gram-negative diplococci Neisseria and Moraxella are oxidase-positive. [2] Many Gram-negative, spiral curved rods are also oxidase-positive, which includes Helicobacter pylori, Vibrio cholerae, and Campylobacter jejuni.
Catalase test on nutrient agar tests for the production of enzyme catalase, which splits hydrogen peroxide and releases oxygen gas. Oxidase test on nutrient agar tests for the production of the enzyme oxidase, which reacts with an aromatic amine to produce a purple color. Nutrient gelatin tests to detect activity of the enzyme gelatinase.
Pseudomonas stutzeri is a Gram-negative, rod-shaped, non-spore-forming bacterium that is typically 1–3 micrometres long and 0.5–0.8 micrometres wide. [10] It tests positive for both the catalase and oxidase tests.
