Pfleger, Brian Frederick; Agnew, Daniel E.

Cells and methods for producing polyhydroxyalkanoates. The cells comprise one or more recombinant genes selected from an R-specific enoyl-CoA hydratase gene, a PHA polymerase gene, a thioesterase gene, and an acyl-CoA-synthetase gene. The cells further have one or more genes functionally deleted. The functionally deleted genes include such genes as an enoyl-CoA hydratase gene, a 3-hydroxyacyl-CoA dehydrogenase, and a 3-ketoacyl-CoA thiolase gene. The recombinant cells are capable of using producing polyhydroxyalkanoates with a high proportion of monomers having the same carbon length from non-lipid substrates, such as carbohydrates.
