Question

The high salt content in a mannitol salt agar plate helps to separate ___________ from ______________ and __________________ in a mixed sample

Answer 1

Answer:

The high salt content in a mannitol salt agar plate helps to separate pathogenic Staphylococci from bacteria and fungi in a mixed sample

Explanation:

Mannitol Salt Agar is a selective culture medium. It is used when you have a biological sample, or a food, contaminated by various bacteria or fungi, but the researcher wants to know if this sample has colonies of pathogenic Staphylococci.

Staphylococci colonies are resistant to the presence of salt in the culture medium, so they survive in this medium. The pathogenic Staphylococci consume mannitol and have a large colony surrounded by a yellow zone. After seeing this colony, the researcher can isolate it and study it correctly.
