This study attempted to isolate and identify pedospheric microbes originating in dumpsites utilized them for the degradation of selected synthetic polymers first time a cost-effective, ecologically favorable sustainable manner. Specifically, low-density polyethylene (LDPE) polyurethane (PUR) were converted by isolated fungi, i.e., Aspergillus flavus, A terreus, A. clavatus, nigers bacterial coccus filamentous assessed biotransformative assay under simulated conditions. Commendable biodegradative potentials exhibited against that analyzed over span 30 days. Among fungal microbes, highest activity was achieved niger, expressing 55% 40% conversion LDPE PUR, respectively. In case strains, 50% PUR coccus. Fourier transform infrared spectroscopy (FT-IR) thermogravimetric analysis (TGA) analyze degradative patterns terms vibrational thermal characteristics, stereomicroscopic performed visual assessment morphological variations. Profound structural transformations detected FT-IR spectra TGA thermograms microbes. Stereomicroscopic also indicative remarkable transformation surface morphology these after comparison reference samples not treated with any The results are supportive utilization as environmental remediators cleanup persistent polymeric toxins. current work can be further extended successful optimization augmented percentages using other adoption biotechnological tools at practical level.

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

Deleted Journal, Год журнала: 2024, Номер 1(1)

Опубликована: Авг. 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.

Plastics in Agricultural and Urban Soils: Interactions with Plants, Micro-Organisms, Inorganic and Organic Pollutants: An Overview of Polyethylene (PE) Litter

Soil Systems, Год журнала: 2024, Номер 8(1), С. 23 - 23

Опубликована: Фев. 16, 2024

Over the last few decades, different types of plastics have been found in soil with documented or potential negative effects on environment, flora and fauna inhabiting soils, subsequently human health. This article is a global review consequences interactions soil, plants, microbes, organic inorganic pollutants depending land use. It focuses various polyethylene, widely used material strong presence both agricultural urban soils. Although chemical formula (C2H4)n remains same its classifications, behavior polyethylene varies directly depends density, branching, crystallinity, relative molecular mass, resulting many differences properties but also two main forms low high density. However, beyond composition plastics, climatic conditions that apply rural areas determine degree corrosion as well their shape size, affecting reactions indirectly affect them. In plants microbiome present mainly rhizosphere seem to dramatically influence where interaction all these parameters leads changes availability nutrients (phosphorus potassium), percentage matter nitrogen cycle. increase temperature decrease humidity are adsorption heavy metals surface plastics. considered inevitable, perhaps more thorough study them will lead reduction risks pollution environments. research provides promising perspective contribution MP PEs sustainable management systems.
