To screen blue colonies with x-gal plates It's better to use synthetic 
medium (see maniatis) than minimal medium. Don't forget to use 
phosphate buffer because x-gal doesn't work for yeast at the normal acidic 
pH of minimal medium; therefore a neutral pH medium is used (but many 
yeast strains will not not grow very well at this pH...)
