As applications for biodegradable and biologically produced poly[(R)-3-hydroxyalkanoates] (PHAs) grow into more specialized areas, the need to precisely control the repeating unit composition and consequently the physical properties of these polymers has become essential. A previous study reported our development of Escherichia coli LSBJ in order to produce PHA polymers composed of single repeatin ...

- ... Polyhydroxyalkanoates (PHAs) are biorenewable and biodegradable polyesters that have garnered attention as alternatives to more common petroleum-based polymers. One of the current limitations for the widespread use of PHAs is the inability to produce PHA polymers with desired material properties. Previous studies have shown that PHA copolymers consisting primarily of one short-chain-length (SCL) r ...

- ... Glycerine (a biodiesel co-product) and levulinic acid (a pulp and paper co-product) were used as co-substrates for the fermentative synthesis of short-chain polyhydroxyalkanoate (sc-PHA) biopolymers with tunable monomer and molecular weight characteristics. Pseudomonas oleovorans NRRL B-14682 utilized glycerine alone to produce poly(3-hydroxybutyrate) (PHB). When levulinic acid was added to the me ...
