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

Explanation:

Mannitol Salt Agar is highly selective and is widely used to isolate Staphylococcus. These microorganisms are capable of fermenting mannitol which is the source of carbohydrate. High concentrations of sodium chloride inhibit most bacteria except Staphylococcus.

bacteria could be both, harmful and to us. harmful bacteria could make us sick and probably even by getting the chances of getting a disease, but good bacteria fight it off with your immune system. there is always bacteria everywhere we go. we need to make sure to wash our hands after using the restroom, before eating, after eating, after petting an animal too. so you see, bacteria is everywhere and is harmful or . i hope this . : ) : ) : )
