"WebOct 11, 2007 · As its name suggests, K. lactis feeds on lactose, the sugar in milk. When lactose is split into pieces, one of the pieces is galactose. Like baker's yeast, K. lactis can also switch to feeding on galactose. It uses a nearly identical set of genes, too. But there's one remarkable difference. " - Can yeast metabolize lactose

Webthat the number of yeast colonies was smaller and that their diameter was shorter than that reached with the MEF medium reduced in lactose (Fig. 3B). This difference was explained to be due to the incapability of the yeast enzymes to metabolize lactose and that, when metabo-lized, lactose can be used as a source of carbon and energy by cells. WebLactose is sugar. It is in dairy products, so my conclusion would be that yes it can metabolize dairy. I read that there is a specific strain of yeast for breaking down lactose because it is a double sugar.
