A Study of Creation of Tailor-Made Synthetic Properties Pseudomonas Putida in Bacterial Host

BIOTECHNOLOGY

Growing environmental concerns have rekindled interest in the manufacture of sustainable (bio) materials that can replace oil-derived items. Polyhydroxyalkanoates (PHAs) are isotactic polymers that serve as dynamic reservoirs of carbon and reducing equivalents in the central metabolism of producer bacteria. PHAs continue to be a popular starting point for thermoplastic and elastomeric materials that are renewable, biodegradable, biocompatible, and flexible. Pseudomonas species have long been recognised to create high-quality biopolymers, particularly medium-chain-length PHAs. Synthetic biology and metabolic engineering approaches have exploded in popularity in recent years, making it possible to tap into the untapped potential of Pseudomonas cell factories for the synthesis of custom PHAs. An overview of the metabolic and regulatory circuits that control PHA accumulation in Pseudomonas putida is provided in this article, as well as methods to the biosynthesis of new polymers (e.g., PHAs with non-biological chemical components in their structures). The potential for innovative PHAs to disrupt present and future market segments is now closer than ever. The analysis concludes by identifying barriers to widespread acceptance of bio-based PHAs, as well as ideas for programmable polymer biosynthesis in modified P. putida strains using alternate substrates.
