Biobased extraction and depolymerization technology for PHA, PHA monomers, and biomass hydrolysate production

• Aiming at a feasible industrial scale bioplastic (PHAs) production, a microbial-based PHA-extraction technique was developed and investigated for extraction of different kinds of PHAs and a variety of well-studied producing microbial strains. This technology could make bioplastics production free of the use of organic solvents or other recovery chemicals. The technology allows the co-production of other valuable components from non-PHA cellular biomass. Moreover, an enzymatic depolymerization process was developed to produce PHA monomers form the recovered native granules. Via this technology, high-value products can be produced and explored for different innovative applications. Developing and upscaling this bio-based technology could help in production of bioplastic, it monomers, and single-cell hydrolysate at minimum cost and zero-wastes.
