Is Staphylococcus aureus lactose frementing bacteria?

Answer 1

Yes, it can ferment lactose. Mannitol Salt Agar is used to identify S.aureus. When it ferments D-mannitol, it produces an acid which turns the agar yellow from red. S.epidermidis will grow, but the agar remains red.

Answer 2

"Streptococcus pneumoniae cells are Gram-positive, lancet-shaped cocci (elongated cocci with a slightly pointed outer curvature). Usually, they are seen as pairs of cocci (diplococci), but they may also occur singly and in short chains. When cultured on blood agar, they are alpha hemolytic. Individual cells are between 0.5 and 1.25 micrometers in diameter. They do not form spores, and they are nonmotile. Like other streptococci, they lack catalase and ferment glucose to lactic acid."

I know this doesn't directly answer your question, because I have been looking for the answer as well, but I came across this, which states that "Other Streptococci" ferment glucose to lactic acid.

Answer 3

Yes, it does ferment glucose and produces lactic acid.

Answer 4

Pseudomonas aeruginosa does not ferment, or produce acid from lactose.

Answer 5

Yes, glucose can ferment glucose, sucrose, and lactose.
