ClearDevelopment of plastic-degrading microbial consortia by induced selection in microcosms
Scientists used a technique called induced selection to develop communities of microorganisms capable of breaking down common plastics, including polyethylene and polystyrene. Over several rounds of enrichment in lab microcosms, the microbial groups that thrived showed measurable ability to degrade these plastics. The study suggests that harnessing naturally occurring soil microbes could offer a sustainable approach to reducing plastic pollution in the environment.
Microplastic accumulation in soils: Unlocking the mechanism and biodegradation pathway
Researchers reviewed how microplastics accumulate in soil and break down biologically, finding that certain microorganisms can form biofilms on plastic surfaces and use enzymes to slowly degrade the polymers — though conditions like pH, temperature, and moisture must be optimized and new plastic-degrading microbes need to be identified before this approach can be widely applied.
Isolation, Screening and Characterization of Plastic-Degrading Bacteria From Soil for PWM
Scientists isolated bacteria from soil near garbage sites and identified strains capable of degrading plastic materials, with scanning electron microscopy revealing physical damage — holes and cracks — to plastic surfaces after bacterial exposure within 30 days. The study contributes to the search for soil microbes that could be harnessed for biological plastic waste management. Biodegradation by indigenous soil bacteria could offer a more environmentally friendly alternative to landfilling or incineration of plastic waste.
Microbial Biodegradation of Synthetic Polyethylene and Polyurethane Polymers by Pedospheric Microbes: Towards Sustainable Environmental Management
Researchers isolated fungi and bacteria from dumpsite soils and tested their ability to break down polyethylene and polyurethane plastics.

The study suggests that soil microorganisms naturally adapted to waste environments could offer a cost-effective and eco-friendly approach to managing synthetic plastic pollution.
Microbial remediation of microplastic-contaminated soil, focusing on mechanisms, benefits, and research gaps

This chapter reviews bioremediation strategies for removing microplastics from soil, focusing on microbial and biological approaches to degrading plastic particles smaller than 5 mm. The authors discuss mechanisms of microbial plastic degradation and the promise of bioremediation as a sustainable soil remediation tool.
Investigating the roles of microbes in biodegrading or colonizing microplastic surfaces
Researchers investigated the roles of microbes in biodegrading or colonizing microplastic surfaces, examining how microbial communities interact with plastic polymers in environmental settings. The study characterized the 'plastisphere' — the community of microorganisms that colonize microplastic surfaces — and assessed the extent to which microbial activity contributes to plastic degradation in natural environments.
Microbial Isolates in Microplastic-Polluted Soil
Researchers isolated and characterized microbial communities from microplastic-polluted soil, identifying bacteria capable of colonizing plastic surfaces and assessing their potential roles in plastic degradation and soil nutrient cycling.
Harnessing Microorganisms for Microplastic Degradation: A Sustainable Approach to Mitigating Environmental Pollution
This review surveys microorganisms—bacteria, fungi, and other taxa—capable of degrading microplastics, examining the enzymes, metabolic pathways, and environmental conditions involved, and assessing the practical potential of harnessing these organisms for bioremediation of plastic pollution.
Unravelling the ecological ramifications of biodegradable microplastics in soil environment: A systematic review
Researchers reviewed 85 studies on biodegradable microplastics in soil, finding that when biodegradable plastics fail to fully break down they can disrupt soil structure, nutrient cycling, and microbial life in ways that depend heavily on concentration and plastic type. The review highlights that "biodegradable" plastics are not a simple fix for microplastic pollution in agricultural soils.
[Interaction between microplastics and microorganisms in soil environment: a review].
This review examines how microplastics alter soil microbial community structure and diversity, and how microorganisms in turn colonize plastic surfaces and degrade them through extracellular enzymes — with degradation efficiency dependent on polymer properties and environmental conditions.
Mite-microbe gut symbiosis: Novel concept for plastic degradation and waste management
Researchers propose a novel concept for plastic biodegradation based on mite-microbe gut symbiosis, building on three years of research exploring whether soil microarthropods (mites) and their gut microbial communities could degrade plastic materials. The paper reviews existing evidence on bacterial and fungal plastic degradation and discusses preliminary findings suggesting that mites ingesting microplastics may harbor gut symbionts capable of contributing to plastic breakdown.
