If I was interpreting the results of Durham tubes, Glucose, Lactose, Sucrose, for Staphylococcus Epidermides, How would I do that

Based on the growth you saw on your Lee’s Agar plate, what conclusions can you make about the bacteria present in the yogurt sample?

How much nystatin stock (50 mg/mL) needs to be added to 15 mL of tryptic soy agar to give a final concentration of 50 μg/mL?

Kligler’s Iron Agar:Q10) Give me the expected results for Pseudomonas aeroginosa, Salmonella typhimurium, and Escherichia coli. Pseudomonas aeroginosa, Salmonella typhimurium Escherichia coli.

A mistake was made in preparing the arginine decarboxylase test, and mineral oil was NOT added to the test tube after inoculating with bacteria. If an arginine decarboxylase-positive bacteria species was inoculated into the above arginine-decarboxylase broth without mineral oil, what would likely be the color result of this bacteria in this test? Would this produce a false positive or false negative result? Explain.

I tested organism growth on the MSA plate for strep. pyongenes, strep. pneumonia, s. aureus, and straph. epidermidis and my results were that streptococci organism did not grow or change color and the s.aureus changed color (yellow) and s.epi there was no change in color but they both showed growth. 1. If an unknown gram-positive bacterium was given, what would it mean if it grew on MSA? Name the organisms used above My answer: that it would be either s.aureus or s. epidermis because they are selective for salt-tolerant bacteria and can grow on mannitol 2. what would it mean if it both grew on MSA and turned yellow? Can you add to my answer or correct it. Thank you!
