Do yeast equally utilize all sugars?
Yeast cannot utilize all of the sugars equally well. While glucose, sucrose, and fructose all can be metabolized by yeast, lactose is not utilized at all. Yeast may not have the proper enzymes to either transport lactose across its cell membrane, or it may not have the enzyme needed to convert it from a disaccharide to a monosaccharide.

Why is skim milk sugar not fermentable by yeast?
MILK SUGAR IS FERMENTABLE BY YEAST. BUT IT PREFERS SUCROSE (TABLE SUGAR). IT MOSTLY TAKES LONGER, UNLESS YOU HAVE A YEAST THAT HAS THE ENZYME SYSTEMS FOR LACTOSE (MILK SUGAR), WHICH SOME DOES.
