Abstract
A method is provided for producing medium chain length poly(3-hydroxyalkanoate) (MCL-PHA) with a selected ratio of monomers. A method of controlling the ratio of monomers in MCL-PHA is also provided which includes fermenting naturally occurring microorganisms with a fatty acid substrate, a food source and an additive. The methods provided do not sacrifice cell growth and maintenance and provide high yields of MCL-PHAs. MCL-PHAs are provided that are copolymers of Cn and Cn−2 monomers, where (n is 6-18).
