Polyhydroxyalkanoates (PHA) is a polyester which being fully biodegradable and it is biologically synthesized by microorganism from fermentation of renewable resources such as sugar and plant oils (e.g. palm oil, canola oil, cottonseed oil, etc.).
PHA is synthesized by converting acetyl-CoA which is formed through ẞ-oxidation pathway into acetoacetyl-CoA which is then reduce to (R)-3-hydroxybutyryl-CoA and finally polymerize into PHA.
PHA is capable of being used to fabricate variety of everyday products ranging from food packaging, photographic material, textile fibers, agricultural, medical uses such as drug delivery system, implants, non-woven patches and tissue scaffolding.
PHA is relatively cost-effective and environmental friendly method to ensure our present and future live in a smarter materials world.
