Abstract
Polyhydroxyalkanoates (PHAs) are potential substitutes for petrochemical plastics, with the advantage of being biodegradable and biocompatible. There are several types of PHA, the most studied being poly-3-hydroxybutyrate (P3HB), differing from each other by the monomer composition. One of the limitations of the mass production of PHAs is the price of raw material. The utilization of xylo…
