Abstract
Polyethylene is a plastic pollutant impacting marine life, calling for advanced remediation methods such as biodegradation. However, there is actually limited information on polyethylene-degrading bacteria in the marine environment. Here, we studied bacterial degradation of polyethylene and associated phthalates additives using scanning electron microscopy, Fourier transform infrared, gel permeation chromatography and genomic and transcriptomic techniques. Results show that a deep-sea bacteria, Acinetobacter venetianus F1, can degrade 12.2% of polyethylene after 56 days, following the alkane metabolic pathway. Phthalates were also degraded via the metabolic pathways of benzoic acid and phthalic acid. This is first report of polyethylene-degrading bacteria from deep-sea environments.
期刊介绍:
Environmental Chemistry Letters explores the intersections of geology, chemistry, physics, and biology. Published articles are of paramount importance to the examination of both natural and engineered environments. The journal features original and review articles of exceptional significance, encompassing topics such as the characterization of natural and impacted environments, the behavior, prevention, treatment, and control of mineral, organic, and radioactive pollutants. It also delves into interfacial studies involving diverse media like soil, sediment, water, air, organisms, and food. Additionally, the journal covers green chemistry, environmentally friendly synthetic pathways, alternative fuels, ecotoxicology, risk assessment, environmental processes and modeling, environmental technologies, remediation and control, and environmental analytical chemistry using biomolecular tools and tracers.
