Abstract:L-lactic acid, whose molecular formula is C3H6O3, can be metabolized by human body, which can be widely used in various fields such as food, medicine, daily chemical and industry. However, in the production of L-lactic acid, chemical synthesis, enzymatic method and microbial preparation and fermentation method, microbial preparation and fermentation method has the advantages of low cost, large yield, simplicity and convenience. First of all, this article from the strain of kinds of alternative analysis is made of the advantages of microbial fermentation to produce L-lactic acid, then introduced have developed the optimization technology of L-lactic acid, including strains used in fermentation raw materials, can adapt to the fermentation conditions and the fermentation level in the industrial production, hope to offer a theoretical basis for industrialized mass production.
Keywords:L-lactic acid; microbial fermentation; optical purity
