A platform E. coli strain for the productions of short-chain alkanes, FFAs, fatty esters,and fatty alcohols was developed. The fadE gene was deleted to preventthe degradation of fatty acyl-CoAs. The activity of FebH was promoted for theenhancement of the initiation of fatty acid biosynthesis by fadR gene deletion. A mutantTesA converted short chain fatty acyl-ACPs to the corresponding FFAs. The sequentialreactions of fatty acyl-CoA synthetase, fatty acyl-CoA reductase, and fatty aldehydedecarbonylase converted the short chain FFAs into corresponding alkanes. Theengineered E. coli strain produced up to 580.8 mg/L of short chain alkanes.
