WebThe fermentation profile of homofermentative lactobacilli is dependent upon the level of substrate and the degree of aeration Limiting concentrations of glucose and galactose result in production of lactate, acetate, and CO 2. Under aerobic conditions, cultures produce primarily acetic acid. WebA completely fermented sauerkraut contains 1.8–2.3% acid (calculated as lactic acid) giving a pH of 3.5 or less. Lactic and acetic acids are the predominating acids, but other organic acids such as succinic, malic, and propionic acids may also be formed in smaller quantities.
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 … See more Several chemists discovered during the 19th century some fundamental concepts of the domain of organic chemistry.
