The Progress of Recombinant Escherichia coli for Production of Succinic Acid
重组大肠杆菌产琥珀酸研究进展

Succinic acid is regarded as C4 platform chemical, which has a huge potential market with wide applications in biopolymer, food, medicine, and so on. Production of succinic acid by microorganism fermentation has attracted much attention in recent times. By fermentation, succinic acid could be produced from renewable resources in place of petroleum with low cost and low pollution; especially CO2 could be fixed by microorganism to form the product, which is a promising way to deal with the green gas. Some E. coli have been chosen as good succinic acid producing strains because of their clear genetic backgrounds, convenience to be modified and controlled, and good growth properties with low nutrients requirements. The progress of genetic engineering strategy and metabolic engineering technology for construction of succinic aicd producing recombinant E. coli has been introduced in this paper with the discussion of the future research in this area.
