Slow lactose fermenters
Webb5 nov. 2024 · Lactose fermentation is one of the types of fermentation reactions wherein fermenters derive energy from lactose (a disaccharide) for their benefit, and in the process, lactic acid (lactate) is produced as a bi-product which is … 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.
