Microbial Biodegradation of Synthetic Polyethylene and Polyurethane Polymers by Pedospheric Microbes: Towards Sustainable Environmental Management

Polymers, Journal Year: 2025, Volume and Issue: 17(2), P. 169 - 169

Published: Jan. 11, 2025

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.

Antibiotic resistant bacteria colonising microplastics in the aquatic environment: An emerging challenge

Discover Sustainability, Journal Year: 2024, Volume and Issue: 5(1)

Published: Dec. 5, 2024

Microplastics are present in every environment and serve as a substratum for the adherence of microbes which ultimately leads to formation biofilms. major facilitating biofilms, where due horizontal gene transfer (HGT) colonising bacteria can exchange antibiotic resistance genes (ARGs). Currently, spread ARGs through microplastics is getting research attention. The widespread use plastics antibiotics their mismanagement leading especially aquatic environments. Antibiotic associated with serious emerging threat both human health. Further studies needed enhance our understanding how these pollutants interact environment. Additionally, finding effective management systems crucial reduce risks. This review article focuses on antibiotic-resistant (ARB) environment, environment; ingestion, seafood or contaminated water, ARB humans, causing potential health
