Question

Which of these traits is NOT useful for distinguishing Enterobacteriaceae from Pseudomonas? . Glucose fermentation . Oxidase test .Normal habitat . Gram stain

Answer 1

The trait that is not useful for distinguishing Enterobacteriaceae from Pseudomonas is the Oxidase test. Enterobacteriaceae are usually oxidase-negative while Pseudomonas is oxidase-positive.

Step-by-step explanation:

The trait that is not useful for distinguishing Enterobacteriaceae from Pseudomonas is the Oxidase test.

Enterobacteriaceae are usually oxidase-negative, meaning they do not produce the enzyme oxidase. Pseudomonas, on the other hand, is oxidase-positive.

The other traits mentioned - glucose fermentation, normal habitat, and gram stain - can be used to differentiate between Enterobacteriaceae and Pseudomonas.

Answer 2

The Oxidase test is not useful for distinguishing Enterobacteriaceae from Pseudomonas.

Step-by-step explanation:

The trait that is NOT useful for distinguishing Enterobacteriaceae from Pseudomonas is the Oxidase test. Enterobacteriaceae are usually oxidase-negative, while Pseudomonas is oxidase-positive. The other traits mentioned, such as Glucose fermentation, Normal habitat, and Gram stain, can be used to differentiate between the two bacterial groups.
