Lactic acid bacteria - Wikipedia
These bacteria, usually found in decomposing plants and milk products, produce lactic acid as the major metabolic end product of carbohydrate fermentation, giving them the common name lactic acid bacteria (LAB).
12-1 An introduction to lactic acid bacteria - University of …
Lactic acid bacteria are Gram-positive usually non-motile, non-spore-forming rods and cocci. They lack the ability to synthesize cytochromes and porphyrins (components of respiratory chains) and therefore cannot generate ATP by creation of a proton gradient.
Lactic-acid bacterium | Fermentation, Probiotics, Metabolism
Lactic-acid bacterium, any member of several genera of gram-positive, rod- or sphere-shaped bacteria that produce lactic acid as the principal or sole end product of carbohydrate fermentation. Lactic-acid bacteria are aerotolerant anaerobes that …
Lactic Acid Fermentation - Definition, Process, Equation, & Examples
2022年8月31日 · Lactic acid fermentation is anaerobic respiration occurring without oxygen that breaks down sugars, producing energy in the form of ATP. This process is so named because lactic acid is a byproduct of this reaction. A typical example of lactic acid fermentation is making yogurt by the bacteria Lactobacillus.
Lactic acid fermentation - Wikipedia
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.
Lactic acid bacteria: from starter cultures to producers of …
2018年8月30日 · Lactic acid bacteria (LAB) have been associated since time immemorial with fermentation of foods and their preservation, and today they are clearly the most important group of industrial microorganisms with a market in the range of multibillion dollars.
Recent Advances in Lactic Acid Production by Lactic Acid Bacteria ...
2021年9月14日 · In order to further minimize the cost of lactic acid production, some effective strategies (e.g., effective mutagenesis and metabolic engineering) have been applied to increase productive capacity of lactic acid bacteria.
