in the absence of glucose or lactose , some bacteria are able to use citrate as only source of carcon. alkaline pH change the bromothymol blue indicator from green to blue. pseudomonas can not ferment the glucose and the lactose so it use the citrate as carbon source.

Citrate test result for Pseudomonas aeruginosa?
citrate result is positive in case of pseudomonas aeroginosa. slant and butt both will be positive
Is Alcaligenes faecalis oxidase positive?
yes and no, sometimes it comes out positive and sometimes it comes out negitive
Why are strict aerobes oxidase positive?
Strict aerobes must be oxidase positive because oxidase is an enzyme. It is critical to cellular respiration, specifically the final reduction of oxygen in the electron transport chain.
How can you easily distinguish enterics and pseudomonads?
Enterics are oxidase negative while pseudomonads are oxidase positive.
What result does pseudomonas aeruginosa have on a urease test?
positive
Is Klebsiella pneumoniae oxidase positive?
No, but Pseudomonas aeruginosa is.
The oxidase test is used to differentiate among which groups of bacteria?
Differentitate among members of the genera Neisseria and Pseudomonas which are oxidase positive and Enterobacteriaceae which are oxidase negative.
Pseudomonas Aeruginosa is generally oxidase positive if the organism were refrigerated for an extended period is there a chance that it would produce a negative oxidase reaction?
I couldn't tell you what were the odds, but I hope this helps: You could be killing your oxidase activity if your organism was no longer viable. When identifying organisms you should always use fresh cultures. Regardless, some strains of Pseudomonas aeruginosa can test oxidase negative. a TSI slant would confirm if you were dealing with a presumptive pseudomonad or an enteric. Enterics will have a strong acid reaction (because they ferment) and Pseudomonas would have no acid (or a very weak acid) reaction. Happy streaking!
What Two genera that are oxidase positive?
Neisseria, Alcaligenes, Moraxella, and Pseudomonadaceae are genera of oxidase positive microorganisms.
Is coryne bacterium is oxidase positive?
no.coryne bacterium is oxidase negative.
Is pseudomonas citrate negative?
positive
When was Bradyrrhoa luteola created?
Bradyrrhoa luteola was created in 1860.
When was Digitivalva luteola created?
Digitivalva luteola was created in 1988.
Citrate test result for Pseudomonas aeruginosa?
citrate result is positive in case of pseudomonas aeroginosa. slant and butt both will be positive
Is Alcaligenes faecalis oxidase positive?
yes and no, sometimes it comes out positive and sometimes it comes out negitive
Why are strict aerobic oxidase-positive?
Strict aerobes must be oxidase positive because oxidase is an enzyme. It is critical to cellular respiration, specifically the final reduction of oxygen in the electron transport chain.
