Published: Jan. 4, 2024

Investigations on microplastic (MPs) particles in soils are extremely rare, and the published results often lack comparability due to different sampling, extracting, analytical approaches used. The current techniques for examining tiny MPs soil samples not particularly effective, but minor adjustments method combinations should be explored. complexity of matrix presents challenges developing a standardized approach characterizing removing them effectively, heterogeneity composition, variability their size/shape, interactions with particles, background contamination, methodological variations. This review focuses evaluating various methods extraction, purification, identification, measurement removal complex systems. A recommended methodology extracting from is proposed, aiming provide systematic recovery identification. Furthermore, article discusses sampling plans, drying sieving techniques, density separation methods, special emphasis photocatalytic removal. also addresses encountered such analyses suggests possible solutions, followed by future prospects. Additionally, importance environment highlighted, underscoring need effective methodologies tackling this pressing issue.

Recent trends in microbial and enzymatic plastic degradation: a solution for plastic pollution predicaments

Deleted Journal, Journal Year: 2024, Volume and Issue: 1(1)

Published: Aug. 11, 2024

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.
