An important environmental issue is the pollution caused by poly(ethylene terephthalate) (PET) and emitted monomers terephthalic acid (TPA) ethylene glycol (EG). The TPA biodegradation pathway has been well documented for microbial assimilation of PET; however, PET process marine microorganisms via EG less understood. Here, we demonstrate how bacteria Pseudomonas chengduensis BC1815's membrane-anchored esterase (OF113_10420) breaks down PET. We also explain characteristics this enzyme that strain assimilates pathway. In addition to depolymerizing PET, hydrolyzes BHET MHET generate more efficiently in alkaline circumstances. It discovered P. BC1815 cells exhibiting surface-displayed have potential function as cell biocatalysts breakdown Additionally, look into communities linked pathway, primarily those belonging phyla Proteobacteria Actinobacteriota. Consequently, research on absorption metabolism route increases our knowledge bioremediation environment contributes understanding destiny pollutants environment.

Abstract Degradation, a common problem faced during the processing of recycled poly(ethylene terephthalate) (PET), leads to significant embrittlement products, as result which material loses its applicability. Increased crystallization rate short chains PET and obstructed mobility amorphous phase are main causes enhanced brittleness. In this research, straightforward method is proposed for improving toughness namely devitrification rigid by thermal annealing, results in molecular fraction, thereby promoting ductile deformation. The effects annealing conditions comprehensively evaluated on microstructure macroscopic properties, i.e., impact resistance, films. perforation energy value film found increase threefold, reaching higher than 18 J mm −1 , 10 s treatment at 120 °C. Differential scanning calorimetry, dynamic mechanical analyses, thermally stimulated depolarization current measurements provide evidence fraction under these conditions, key efficient enhancement toughness.

The growing plastics end-of-life crisis threatens ecosystems and human health globally. Microbial plastic degradation upcycling have emerged as potential solutions to this complex challenge, but their industrial feasibility limitations thereon not been fully characterized. In perspective paper, we review literature describing both transformation of monomers into value-added products by microbes. We aim understand the current combining these a single, closed-loop process. Our analysis shows that microbial is currently rate-limiting step "closing loop", with reported rates are orders magnitude lower than those pathways upcycle products. further find neither nor demonstrated at sufficiently high justify industrialization present. As way address limitations, suggest more investigation mixotrophic approaches, showing which leverage unique properties such ethylene glycol might improve motivate process development.

Plastics are an essential component of modern life, but the plastic waste has caused significant environmental pollution and economic losses. The effective solution to these problems is biodegradation high-value conversion waste. After biodegradation, broken into smaller molecules eventually transformed innocuous substances like water, carbon dioxide biomass. High-value enables be converted products with higher value friendliness. Based on this, we summarize methods bioplastics analyze shortage methods. Subsequently, progress converting degradation value-added chemicals, comprehensively advantages disadvantages bioconversion process, propose some strategies address disadvantages. Finally, significance establishing a microbial-based process that integrates conversion, potential strategies.

The abundant production of plastic materials, coupled with their recalcitrant nature, makes them a major challenge as pollutants. Recently, the use microorganisms and enzymes have emerged promising solution to this issue. This biotechnological approach holds significant potential for degradation polyethylene terephthalate (PET), polyester formed by terephthalic acid (TPA) ethylene glycol. polymer can be completely depolymerized using PETase MHETase. Furthermore, some metabolize monomers PET, providing opportunity upcycling waste into value-added products. bacterium Comamonas testosteroni convert TPA bioplastic polyhydroxybutyrate (PHB). In study, C. was engineered express fusion PET-degrading FAST-PETase IsMHETase, verifying that recombinant strain depolymerizes PET releasing produces PHB. Our findings highlight chassis synthetic biology strategies aimed at recycling waste.
