Protocol for GAL1 promoter induction.

another thing to look at is to make sure that your strain is not Gal1
minus.  These strains can not use Galactose as a carbon source; so
these need to be supplemented with Raffinose as a carbon source.  But I
doubt that this is the case in your situation because it would have
been pretty obvious if your culture did not grow.

I concur with the previous post of harvesting after a short induction
time 2-5 hrs versus o/n.
