E. coli is an intestinal organism, and staphylococcus epidermidis resides on the skin. what do you hypothesize will occur when both are inoculated onto mannitol salt agar

The options

A. Both organisms will grow since they are both ubiquitous of 20.

B. Neither organisms will grow beacause 75% salt inhebits at organisms.

C. The salt inhibits the growth of E.coli which is not a halophyte, but S.epidermidis grows.

D. The S epidernidis will not grow since it must exist at as a pure cuture the E.coli will grow."

C.

Agar is characterised by Escherichia coli not growing and Staphylococcus epidermidis growing and observing colorless to pink colonies.

Explanation:

This agar a differential medium for mannitol fermentors,

 It encourages the growth of a group of certain bacteria while inhibiting the growth of others.

Note: an acidic by product is formed if an organism can ferment mannitol, that will cause the phenol red in the agar to turn yellow. 

i think that c)gold was found there

but i am not sure
