What suggestions do you have to get rid of baceria within a yeast growth by using culture medium?

Yeast are usually more tolerant of low pH than bacteria. If you can put the yeast on a medium with a lower pH the bacteria might not survive as well. This is why citrus fruit are spoiled by mold more often than they are spoiled by bacteria, for example.


Plate the mixed culture out on solid media (nutrient agar) and pick up a well isolate yeast colony and streak it out on another agar plate. Then pick up another well isolated and start a new culture.
