Plastic pollution is an ever-escalating issue with detrimental effects on both the environment and human health. breaks down into smaller pieces, depending size they are called macroplastics, microplastics (MPs), nanoplastics (NPs). Some of these particles can easily enter food chain causing toxicity to many plants animals. The extensive use synthetic polymers such as polyethylene (PE), polyvinyl chloride (PVC), polystyrene (PS), terephthalate (PET) poses substantial environmental concerns due their degradation-resistant characteristics. One ways microorganisms address this by producing enzymes. This review examines recent advancements in enzymatic degradation commercial-grade pure polymers, including effectiveness enzymes laccases, proteases, cutinases, PETase, MHETase, governing mechanisms across various plastic categories. Bioinformatic tools multi-omics, molecular docking, enzyme mining particularly useful identifying unconventional biocatalysts plastic-degrading microbes a culture-independent manner. Furthermore, techniques enhance catalytic efficiency degrading (PDEs) using modern approaches protein engineering, mutations, chimeric fusion, etc. have also been reviewed. accentuates pivotal role microbial mitigating pollution, associated challenges, suitable prospects achieve closed-loop recycling future.

The persistence of plastics, particularly polypropylene (PP), and their conversion into microplastics (MPs), specifically PP-MPs, have emerged as serious ecological threats to soil aquatic environments. In the present study, we aimed isolate a microbial consortium capable degrading PP-MPs. results revealed that three consortia (CPP-KKU1, CPP-KKU2, CPP-KKU3) exhibited ability degrade achieving weight losses ranging from 11.6 ± 0.2 % 17.8 0.5 after 30 days. Fourier transform infrared (FTIR) spectroscopy analysis confirmed degradation through oxidation, evidenced by presence new functional groups (-OH -C=O). particular, CPP-KKU3 showed highest efficiency, with scanning electron microscopy (SEM) revealing surface cracking treatment. Additionally, gas chromatography-mass spectrometry (GC-MS) identified various intermediate compounds, including heterocyclic aromatic phenyl groups, methylthio derivatives, ethoxycarbonyl indicating complex biochemical processes were likely mediated enzymes. Furthermore, polyhydroxybutyrate (PHB) production these was also investigated. result both CPP-KKU2 successfully produced PHB, demonstrating superior performance in terms PP-MP PHB production. Metagenomic abundant carbohydrate-active enzymes (CAZymes), glycosyl transferases glycoside hydrolases, which are associated MP digestion. This study presents promising bioremediation approach addresses plastic waste sustainable bioplastic production, offering potential solution for environmental pollution.

Polystyrene, a widely used thermoplastic, polluting the environment in form of micro/nanoplastics. Though traditional methods are commonly employed for plastic management, microbial degradation remains more promising and eco-friendly approach. The present study focused on biodegradation expanded polystyrene (EPS) using microbes isolated from plastic-contaminated sites assessing degradants their industrial importance. An isolate, VITARK5, was able to grow well Bushnell Haas agar containing EPS as only carbon source chosen studies. With robust glycolipid biosurfactant synthesis biofilm formation, VITARK5 identified be Pseudomonas aeruginosa. In order biodegradation, inoculated broth thin film incubated at 37°C 120 rpm two weeks. After gravimetric analysis showed 14.53% weight reduction compared control. Formation cracks rough surfaces observed under scanning electron microscopy. GCMS presence industrially important chemicals such valerenol, 3-hydroxyl, 4-methoxy benzaldehyde, oxalic acid, dodecane, azacyclododecane hexadecane. FTIR spectroscopy confirmed functional groups associated with its additives. Biofilm formation production synergistically would have promoted biodegradation. findings suggest that isolate P. aeruginosa sp.VITARK5 may bioremediation valorisation achieve circular bio-economy.
