Lactic acid synthesis can occur through various processes, including bacterial fermentation of carbohydrates and chemical synthesis from acetaldehyde. The production of lactic acid predominantly involves fermentation, with the possibility of producing racemic lactic acid consisting of a 1:1 mixture of stereoisomers or mixtures with up to 99.9% -lactic acid by microbial fermentation . Additionally, lactic acid is an alpha-hydroxy acid (AHA) and is used as a synthetic intermediate in many organic synthesis industries and various biochemical industries

 

Furthermore, lactic acid can be produced by chemical synthesis from cellulose catalyzed by lead(II) ions in water, providing a high-value chemical used for the production of fine chemicals and biodegradable plastics buy 80532-66-7

It is also commercially produced in large scale and used in several different industries, including pharmaceutical, food, and textile industries

 

In the context of lactic acid bacteria, lactic acid synthesis is essential for producing adenosine triphosphate (ATP), the universal molecular carrier of metabolic energy in living cells, in the context of anaerobic fermentation. This metabolic energy supplied by lactic acid fermentation is crucial to drive the cell's biosynthetic machinery at the rates required for growth and survival

 

In summary, lactic acid synthesis involves both natural processes, such as bacterial fermentation, and chemical synthesis, and it plays a crucial role in various industries and in the metabolic processes of lactic acid bacteria.
