WebbOthers, like Salmonella, Yersinia and Shigella can’t ferment lactose so their colonies will be colorless. Now, Serratia marcescens and also Citrobacter are slow lactose fermenters, so they are a bit lazy, but eventually ferment lactose. So at first, the colonies appear colorless but 48 hours later, they turn pink.

Lactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars (also, disaccharides of six-carbon sugars, e.g. sucrose or lactose) are converted into cellular energy and the metabolite lactate, which is lactic acid in solution. It is an anaerobic fermentation reaction that occurs in some bacteria and animal cells, such as muscle cells.
