Polyhydroxyalkanoates
(PHAs) as one of biomaterials to replace plastics are intracellular
energy storage linear polyesters produced in nature by bacterial
fermentation of sugar and lipids. Due to biocompatibility and
biodegradability of biologically-produced PHA for possible uses as
plastics with promising physical and chemical characteristics (e.g.,
can be changed by blending and/or modifying the surface), PHAs
could be applicable to be biodegradable polymers for green technology
of sustainable development [2].
