Biofuel (gasoline) production by metabolically engineered Escherichia coli |
초록 |
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 prevent the degradation of fatty acyl-CoAs. The activity of FebH was promoted for the enhancement of the initiation of fatty acid biosynthesis by fadR gene deletion. A mutant TesA converted short chain fatty acyl-ACPs to the corresponding FFAs. The sequential reactions of fatty acyl-CoA synthetase, fatty acyl-CoA reductase, and fatty aldehyde decarbonylase converted the short chain FFAs into corresponding alkanes. The engineered E. coli strain produced up to 580.8 mg/L of short chain alkanes.
