Yes micrococcus luteus, along with micrococcus roseus both grow on MSA. But, they do not fermente on this agar giving a negative test. However, Staphylococcus aureus grows on MSA and fermentes giving a positive test. *Side note* MSA plate is used to test for G+ coccus. The plate contains salt and salt "loving" bacteria will grow and show yellow colony, example of S. aureus.

Do Gram negative organisms grow on MSA plates?
Yes
What does msa plates test for?
Shows if bacteria can tolerate salty conditions. If so, it will grow, if not, no growth will occur.
Can enterobacter aerogenes grow on mannitol salt agar?
the bacteria dont ferment in MSA, there is no growth on the plat
Can proteus vulgaris grow on msa?
No it cannot, since it isn't halophilic.
Does S epidermidis test positive for MSA agar test?
Yes. S. epidermidis is a bacterial species found commonly on the skin as a part of a human's natural bioflora. Sweating releases salt and causes the surface of our skin to be very salty, providing an environment in which many bacteria would normally perish. S. epidermidis, however, prefers such an environment and thus it is also able to grow regularly when cultured on Mannitol Salt Agar plates.
Does micrococcus varians grow on msa plates?
No it doesn't.
Why is micrococcus luteus negative for oxidase?
You probably got a false negative. M. luteus should be oxidase +. To determine M. luteus do a MSA plate which should not produce acid and barley grow. That means the plate will look red with a streak of yellow colonies due to the fact that M. luteus produces a yellow pigment.
Can bacillus megaterium grow in MSA plates?
yes
Do Gram negative organisms grow on MSA plates?
Yes
Does s. epidermidis grow on msa?
Streptococcus cannot grow on MSA plates because MSA is a selective and differential media. It is selective because only certain microorganisms can grow on it due to its high NaCl content, in which this concentration - near 10% in MSA - has an inhibitory effect on most bacteria, such as Streptococci.
What does msa plates test for?
Shows if bacteria can tolerate salty conditions. If so, it will grow, if not, no growth will occur.
Did lactobacillus grow on mannitol salt agar?
Yes. M. smegmatis is a gram + bacteria, and MSA plates select for gram + bacteria.
Can bacillus subtilis grow on msa?
yes It can, because MSA grows gram positive bacteria.
Can enterobacter aerogenes grow on mannitol salt agar?
the bacteria dont ferment in MSA, there is no growth on the plat
Can Streptococcus grow on MSA?
MSA stands for mannitol salt agar. Streptococcus can not grow on this type of agar. This is because it has a very high salt content, which allows only certain microorganisms to grow in it.
Can proteus vulgaris grow on msa?
No it cannot, since it isn't halophilic.
Is CSS the same as MSA?
