Microbe‐mediated biodegradation of microplastics from wastes
Microplastics (MPs) with slow degradation rates carry toxins and pathogens from surroundings, accumulate and pollute the environment. They bio‐accumulate on humans and other lifeforms leading to health concerns, including inflammatory lesions, oxidative stress and increased cancer risk, thus requiring immediate remediation actions. This review summarizes, categorizes and analyses recent findings on MP source, transit and environmental toxicity and explores their microbe‐mediated breakdown. Various micro‐organisms such as fungi, bacteria, algae and protists interact with and build biofilm on MP surfaces and alter their surface morphology for their degradation. Pure strains and microbial consortia have been successfully able to degrade MPs. Extracellular enzymes are produced by these micro‐organisms that convert the complex recalcitrant polymeric structure of MP to simpler forms. Further, knowledge of factors associated with MP degradation along with the development of genetic tools enhances the rate of microbial degradation with consortium having an advantage over single bacterium‐mediated MP transformation, which has been discussed.

期刊介绍: Water and Environment Journal is an internationally recognised peer reviewed Journal for the dissemination of innovations and solutions focussed on enhancing water management best practice. Water and Environment Journal is available to over 12,000 institutions with a further 7,000 copies physically distributed to the Chartered Institution of Water and Environmental Management (CIWEM) membership, comprised of environment sector professionals based across the value chain (utilities, consultancy, technology suppliers, regulators, government and NGOs). As such, the journal provides a conduit between academics and practitioners. We therefore particularly encourage contributions focussed at the interface between academia and industry, which deliver industrially impactful applied research underpinned by scientific evidence. We are keen to attract papers on a broad range of subjects including: -Water and wastewater treatment for agricultural, municipal and industrial applications -Sludge treatment including processing, storage and management -Water recycling -Urban and stormwater management -Integrated water management strategies -Water infrastructure and distribution -Climate change mitigation including management of impacts on agriculture, urban areas and infrastructure
