Question

Fermentation of glucose (OF tube) helps differentiate Staphy from?

a) Micrococcus
b) Streptococcus
c) Enterococcus
d) Bacillus

Answer 1

Fermentation of glucose in an OF tube can help differentiate Staphylococcus from Micrococcus, Streptococcus, Enterococcus, and Bacillus.

Step-by-step explanation:

Fermentation of glucose in an OF tube can help differentiate Staphylococcus from Micrococcus, Streptococcus, Enterococcus, and Bacillus. Staphylococcus, including Staphylococcus aureus, is capable of fermenting glucose, which produces acid that causes a pH change and a color change in the OF tube. Micrococcus, Streptococcus, Enterococcus, and Bacillus are unable to ferment glucose, so there will be no color change in the OF tube for these bacteria.
