Most of the antibiotics used in cell culture (penn-strep, gentamycin, etc.)
are only effective against prokaryotes.  Fungicides are typically required
to kill yeast.  However, this is not to say that yeast won't have any adverse
responses to the prokaryote-targeted antibiotics, if it's yeast you're 
TRYING to culture.  (But who in their right mind would want to do this?)  :-)
