Abstract: Methods are provided for biological conversion of anhydrosugars, such as anhydrosugars found in a pyrolysis oil, to fatty acid alkyl esters. The methods can include use of a genetically modified Escherichia coli (E. coli) bacteria that can convert levoglucosan and/or other anhydrosugars into fatty acid alkyl esters without requiring formation and conversion of an intermediate compound external to the bacteria. Optionally, the methods can be used in combination with methods for production and/or separation of increased amounts of levoglucosan from pyrolysis of biomass.
