The recombinant cells may be modified to exhibit increased biosynthesis of an ester compared to a wild-type control. The recombinant cell may be incubated in medium that includes carbon source under conditions a effective for the recombinant cell to produce an ester. This disclosure also describes a method that generally includes introducing into a host cell heterologous a polynuc - leotide encoding at least one polypeptide that catalyzes a step in converting a carbon source to an ester, wherein the at least one polynucleotide operably linked is to a promoter so that the modified host cell catalyzes conversion of the carbon source an ester. to
