Research Progress of Lactic Acid Synthesis Technology
Lactic acid,as an important organic acid,has been widely used in food industry,pharmaceutical manufacturing and biodegradable plastics.In this paper,the synthesis methods of lactic acid are reviewed,including the traditional fermentation method,the new chemical conversion method,enzyme method and electrochemical synthesis method.In contrast,the fermentation method mainly focuses on the improvement of genetically engineered strains,the optimization of fermentation technology,and the screening of high-yield and stable strains.In chemical conversion,researchers are working to improve the synthesis path and need to find more environmentally friendly and sustainable production methods;Enzymatic method combines the biocompatibility of fermentation method with the controllability of chemical conversion method,which is expected to play a greater potential in the production of lactic acid in the future.Electrochemical synthesis has the problem of high energy consumption in engineering conversion.The future research direction of lactic acid synthesis technology was prospected,and the importance of developing high efficiency,low cost and environment friendly lactic acid production process was emphasized.
