Bacteria in a Yeast Culture
Country: United States
Date: July 2008
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.
