Abstract: Abstract: Diminishing petroleum reserves and the rapid accumulation of greenhouse gases have prompted an interest in the development of biofuels and oleochemicals from renewable sources. Based on this purpose， fatty acid biosynthesis system， a route for producing high-energy density， liquid biofuels and high-value oleochemicals， has received significant attention. This review first introduced classic E. coli fatty acid biosynthesis system， and summarized recent achievements on the engineering the fatty acid metabolic system to produce fatty acids and fatty acid derivatives. Most importantly， this review introduced the in-depth excavation of the fatty acid biosynthesis pathway by using the in vitro reconstituted system， and engineering the fatty acid metabolic system in vivo according to the obtained information to release the potential of the fatty acid biosynthesis system.
