Polyhydroxyalkanoates as a source of chemicals, polymers, and biofuels

► Microbial polyhydroxyalkanoates (PHA) are a source of polymers, chemicals and biofuels. ► A Pseudomonas putida based platform for producing PHA homopolymers and block copolymers has opened a new area to diversify PHA monomers and structures. ► Further PHA development appears to be limited only by imagination and practices.
