Abstract
Polyhydroxyalkanoates (PHAs) are polyesters synthesized from excess carbon source and nutrient limitation in the form of bacterial granules for energy reserve intracellular. PHAs have physico-chemical properties similar to synthetic polymers of petrochemical origin, besides being ecologically viable due to their high biodegradability. Among PHAs, poly-3-hydroxybutyrate (P3HB) is the most …
