Why Use mannitol salt agar?

Mannitol salt agar supports growth of organisms that can grow in a high salt concentration, particularly Staphylococcus species and halophiles.

Can staphylococcus aureus ferment lactose?

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.

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.

Gram-positive bacteria grows in Mannitol agar because it contains a high level of salt. This type of agar allows only certain types of bacteria to grow, making it selective.Ê

Does proteus mirabilis grow on mannitol salt agar?

No it doesn't because it doesn't ferment mannitol. P. mirabilis can actually grow on a MAC agar, but it is colorless. I actually had this lab in Micro260 today.An MSA agar has 7% high salt concentration and provides growth for S. aureus bacteria turning it yellow/gold. An MSA agar is selective for osmotolerant bacteria meaning for bacteria that can grow in different salt concentrations, and it's differential because it can ferment mannitol.
