Poly(3-hydroxybutyrate) (P(3HB)) is an attractive biodegradable plastic alternative to petroleum-based plastic. However, the cost of microbial-based bioplastic production mainly lies in cultivation medium. In this study, we screened isolates capable synthesizing P(3HB) using sugarcane bagasse (SCB) waste as a carbon source from 79 Bacillus that had previously shown commercial The results revealed isolate S356, identified cereus 16S rDNA and gyrB gene analysis, highest accumulation. yield (5.16 g/L, 85.3% dry cell weight) was achieved by cultivating B. S356 optimal medium with 1.5% total reducing sugar SCB hydrolysate 0.25% yeast extract nitrogen source. Transmission electron microscopy analysis showed accumulation approximately 3–5 granules each cell. Proton nuclear magnetic resonance spectroscopy Fourier transform infrared analyses confirmed polymer extracted P(3HB). Notably, during for production, also secreted bacteriocin, which high antibacterial activity against same species (Bacillus cereus). Overall, work demonstrated possibility co-producing eco-friendly bacteriocin renewable resources potential S356.

Since the 2005 discovery of first enzyme capable depolymerizing polyethylene terephthalate (PET), an aromatic polyester once thought to be enzymatically inert, extensive research has been undertaken identify and engineer new biocatalysts for plastic degradation. This effort was directed toward developing efficient enzymatic recycling technologies that could overcome limitations mechanical chemical methods. These enzymes are versatile molecules obtained from microorganisms living in various environments, including soil, compost, surface seawater, extreme habitats such as hot springs, hydrothermal vents, deep-sea regions, Antarctic seawater. Among plastics, PET polylactic acid (PLA) have primary focus depolymerization research, greatly enhancing our knowledge degrade these specific polymers. They often display unique catalytic properties reflect their particular ecological niches. review explores recent advancements marine-derived can depolymerize synthetic polymers, emphasizing structural functional features influence efficiency catalysts biorecycling processes. Current status future perspectives also discussed, with a on underexplored marine resources.
