In the traditional lactic acid production methods, DL-lactic acid can be synthesized by chemosynthesis method, its cost is too high and its raw materials are venomousness; Optical purity lactate can be produced by Enzyme catalysis. Due to it"s more complicated technology and it"s high demanding for working condition, microbial fermentation has become the important method to produce lactic acid.
