enzymatic conversion of pyruvate

Lactate dehydrogenase from the highest activity of Lactobacillus DSM20196 confusion cells obtained in potassium lactate dehydrogenase, a non-optically active pyruvate as substrate D-lactic acid can be obtained.
Industrial production of lactic acid fermentation method and the method is mainly synthesis. Because fermentation process is simple, abundant raw materials, develop and become more mature earlier lactic acid production methods, lactic acid production accounts for about 70 or more, but long cycle, only batch or semi-continuous production and quality of domestic Sodium lactate fermentation to international standards. Chemical method can achieve large-scale continuous production of lactic acid and lactic acid synthesis has also been the U.S. Food and Drug Administration (FDA) approval, but the raw materials are generally toxic, does not meet the requirements of green chemistry. Enzymatic process is complex, and its industrial application needs further study.
