Then it was inoculated in BCP Mannitol broth. The color change to yellow indicated acid production by Mannitol fermentation. This indicated that the unknown was Staphylococcus aureus or Enterococcus faecalis By contrast, nonpathogenic Staph such as Staphylococcus epidermidis (a.k.a. Staph epi), the normal flora that grows on human skin, does not ferment mannitol. When Staph epi grows on Mannitol Salt, the naturally orange-pink color of the agar doesn't change, since S. epidermidis doesn't eat mannitol or produce the resulting organic acid wastes

1) Mannitol salt agar(MSA) media is the selective media which has high salt concentration. Staphylococcus aureus grows on MSA because these bacteria are salt resistance. This is due to the peptidoglyc view the full answe Staphylococcus epidermidis is salt-tolerant (halophilic) so it will grow on the mannitol salt agar (MSA) Plate and will produce colonies. However, Staphylococcus epidermidis does not have the ability to ferment mannitol, because it lacks the enzyme coagulase. In other words, Staphylococcus epidermis is considered coagulase - or coagulase-negative. Since there is no fermentation, no acidic. Therefore, this ensures that Unknown A is indeed Staphylococcus aureus. Unknown B (gram negative) After doing a gram stain on the bacterium, it was determined that this bacterium was a gram negative. The next step was to continue with another test. A Mannitol agar plate was obtained and inoculated with the bacterium
