The production of polyhydroxyalkanoates is the only alternative to solve the issue as they are biodegradable 28 . Gold medal for our project!! • They are the strongest candidates to replace the conventional plastics in the future. Polyhydroxyalkanoates (PHAs) are bio-polymers, synthesized by microorganisms as lipid inclusions for energy storage in granular forms within the cellular structure (Poli et al., 2011). However, commercialization of PHA is impended by its high total production cost, which half of it are from the cost of pure carbon source feedstock. R. eutropha JMP 134 and other strains belonging to this species are models for studying microbial production of “polyhydroxyalkanoates (polyesters produced in nature by bacterial fermentation of sugar or lipids), and chemolithoautotrophic (organisms utilize inorganic compounds as energy sources) metabolism in aerobic heterotrophs. Polyhydroxyalkanoates (PHAs) are biodegradable and biocompatible plastics.
