The advance on modification of polyhydroxyalkanoates synthase and construction of metabolic pathways

Polyhydroxyalkanoates(PHA) are biopolyesters,which are accumulated intracellularly in granule as carbon and energy storage materials by many microorganisms under unbalanced conditions.PHA has drawn much attention due to its good material properties,such as biodegradability,biocompatibility and the potential substitutes of chemical plastic.However,PHA composed of short-chain-length or single hydroxycarboxylic acid monomer possesses some undesired...
