Yeast love to grow at pH 4 - 4.5;  It's a very rare bacterium that will
tolerate such conditions.  I would question my sources if the media recipe
called for pH > 6.

Recall that women get yeast infections, not bacterial infections because
the vaginal environment is acidic.  Also note that they use "monistat" a
fungicide to retard yeast growth (not kill it).  Antibiotics are not used
to treat yeast infections.
