- Describe a circumstance (e.g. in its’ natural environment) where Staphylococcus species bacteria might benefit from being salt tolerant. - How might the ability to perform hemolysis benefit a hemolytic organism in its’ natural environment? - Imagine that you have a culture containing a single bacterial species. This culture may be one of several possible species. Describe a scenario where you use Mannitol Salt agar, Blood Agar, and EMB plates to identify the unknown bacterial species. That is, how would...

Q14. In the lab info it says that as a rule, most microbes can adjust to a range of salt concentrations. 7/29/2019 Which cell structure allows microbes to physically withstand hypotonic environments? Cell wall MSA has two properties. It is both selective and differential. When bacteria grow on this media, there is a visible difference between bacteria that ferment mannitol, and the bacteria that do not See Figure 2 (a)-effects of selective/differential media. Q15.
