Based on your experimental results, categorize each microbe as preferring isotonic environments, being halotolerant, or as a hal
NISA [10]

The microbes present in the experiment were:

S. cerevisiae

S. epidermis

A way of categorizing microbes is according to the environment that they need to live in. In other words, we can classify them as isotonic, halotolerant and halophile.

If we put these two microbes in solutions of increasing concentrations, 1%, 7% and 15%, we will see that:

  • S. cerevisiae only grows when it is in a 1% solution.
  • S. epidermis only grows when it is in a 1% and 7% solution.

In conclusion, S.cerevisiae prefers an isotonic environment. S. epidermis is halotolerant since it can grow in a more hypertonic environment. As none of them grows in a highly hypertonic solution, neither of them are halophile.

The patient will be given a positron emitting substance most commonly fluorodeoxyglucose or FDG via intravenous injection. After which, the patient will go to the PET machine and the PET machine will measure the positron emitted throughout the body.
