Abstract:
1. A method for making low molecular weight hydrocarbons from a biocrude, which method comprises: (a) obtaining a recombinant microorganism comprising one or more polynucleotides encoding one or more polypeptides having acetyl-CoA carboxylase (accABCD) activity (EC 6.4.1.2, 6.3.4.14), wherein the one or more polynucleotides are exogenous to the recombinant microorganism or wherein one or more endogenous polynucleotides encoding one or more polypeptides having accABCD activity are overexpressed in the recombinant microorganism; (b) culturing the recombinant microorganism in a culture medium containing a carbohydrate as the carbon source under conditions effective to express the one or more polynucleotides, wherein the recombinant microorganism produces a biocrude; and (c) cracking the biocrude resulting in low molecular weight hydrocarbons.
