Abstract
Acrylic acid is one of the important industrial chemicals,it is widely used in many fields such as coating materials and absorbent materials.Currently,it is produced mainly through the oxidation of propylene.However,due to the decrease of petrochemical resource and the environmental problems caused by the process of manufacture,acrylic acid preparation using bioprocess has become a research hotspot.The properties of acrylic acid and its applications in industry were introduced,meanwhile the recent advances in the research and development of acrylic acid biosynthesis were reviewed.The methods were classified into entire biological method and semi-biological method according to whether chemical processing methods were used in the procedure of manufacture.The semi-biological method mainly included the chemical dehydration of lactic acid and the biotransformations of acrylonitrile and acrylamide.Entire biological methods mainly included the biological dehydration of lactic acid,3-hydroxylpropionic acid pathway,the direct fermentation of saccharides and DMSP pathway.More emphasis were put on the dehydration of lactic acid,just as lactic acid preparation had been a proven technique.For the factors above,the biological dehydration of lactic acid meet the demand of sustainable development and it was introduced detailedly.Simultaneously,the advantages and disadvantages of each method were discussed,providing suggestions for the following research of producing acrylic acid by biomass.
