Not relevant to microplastics — this study examines how earthworms and plants work together to remove chromium from contaminated soils, testing bioremediation effectiveness across different soil acidities and pollution levels.
Global Situation of Bioremediation of Leachate-Contaminated Soils by Treatment with Microorganisms: A Systematic Review
This systematic review found that bioremediation using microorganisms is an effective and low-cost approach for treating soils contaminated by landfill leachate. Bacterial consortia were most successful at degrading heavy metals and organic pollutants, though treatment effectiveness depends heavily on soil type and contamination levels.
Biodegradation of polypropylene in presence of chromium mediated by Stenotrophomonas sp. and Lysinibacillus sp. isolated from wetland sediments
Researchers isolated bacteria from wetland sediments contaminated with both plastics and chromium, identifying Stenotrophomonas sp. and Lysinibacillus sp. as the most effective strains for polypropylene biodegradation based on biofilm formation capacity, and confirmed their ability to biodegrade PP and bioreduce hexavalent chromium under co-contamination conditions.
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.
Isolation of a soil bacterium for remediation of polyurethane and low-density polyethylene: a promising tool towards sustainable cleanup of the environment.
A soil bacterium tentatively classified in the Pseudomonas genus was found to biodegrade both polyurethane and low-density polyethylene plastics. The discovery of a single bacterial strain capable of degrading two different types of plastic is a step toward developing practical microbial tools for plastic waste remediation.
Degradation of microplastics in artificially polluted soil by bacterial and fungal isolates originating from landfill leachate
Researchers tested whether bacterial and fungal isolates from landfill leachate could degrade polyethylene and polypropylene microplastics in artificially polluted agricultural soil, finding that the microbial isolates showed measurable degradation activity against both polymer types.
Interaction of Heavy Metals with Plastic Contaminated Soil
This study reviews and investigates how microplastic contamination in soil interacts with heavy metals, finding that plastic particles alter soil behavior and can change how toxic metals move through and bind to soil. Because microplastics increase soil permeability and adsorb metals, their presence in landfills and near industrial sites raises concern about groundwater contamination from combined plastic and metal pollution.
Biodegradation of municipal plastic wastes collected from solid waste landfills of Jammu, India
This study tested soil bacteria and fungi isolated from a landfill in Jammu, India, for their ability to biodegrade low-density polyethylene and other municipal plastic wastes. Identifying landfill-derived microorganisms capable of degrading common plastics could lead to bioremediation strategies for plastic-contaminated sites.
Enhanced Adsorptive Bioremediation of Heavy Metals (Cd2+, Cr6+, Pb2+) by Methane-Oxidizing Epipelon
Methane-oxidizing bacteria in sediment biofilms (epipelon) were found to also effectively adsorb and remove cadmium, chromium, and lead from water. This research is relevant to bioremediation of heavy metal pollution, which often co-occurs with microplastic contamination in aquatic sediments.
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.
Biodegradation of Polypropylene in Presence of Chromium Mediated by Stenotrophomonas sp. and Lysinibacillus sp. Isolated from Wetland Sediments
Researchers isolated bacteria from contaminated wetland sediments in the Paraná Delta, Argentina and screened 73 isolates for ability to simultaneously bioremediate chromium and degrade polypropylene, identifying Stenotrophomonas and Lysinibacillus species as promising dual-function candidates.

Researchers isolated and identified bacteria from the Putri Cempo Landfill in Surakarta, Indonesia using Soil Extract Media, then evaluated their ability to degrade different types of plastic contaminants found in agricultural environments, aiming to develop bioremediation solutions for microplastic contamination in farmland soils.
Bioremediation of environmental wastes: the role of microorganisms
This review discusses how bacteria, fungi, and algae can be used to clean up environmental pollution including plastic waste, heavy metals, and pesticides through a process called bioremediation. These biological cleanup methods are relevant to microplastic pollution because certain microorganisms may be able to break down plastic particles in contaminated soil and water.
Selective Isolation and Identification of Microorganisms with Dual Capabilities: Leather Biodegradation and Heavy Metal Resistance for Industrial Applications
This paper is not directly about microplastics; it investigates bacteria that can biodegrade chromium-tanned leather and tolerate heavy metals, aimed at improving industrial waste treatment for the leather tanning industry.
Investigating the distribution of microplastics in soils from e-waste dismantling sites and their adsorption of heavy metals
Researchers studied microplastic distribution in soils at electronic waste dismantling sites and examined how those microplastics absorb heavy metals. They found that microplastic abundance was significantly higher in contaminated soils near e-waste facilities, and that different plastic types varied in their capacity to adsorb metals like copper, lead, and cadmium. The findings suggest that microplastics in e-waste contaminated soils may act as carriers that spread heavy metal pollution through the environment.
Risk assessment of potentially toxic elements, microplastics, and microorganisms in groundwater around municipal solid waste landfill
This study assessed contamination from toxic metals, microplastics, and harmful microorganisms in groundwater near a closed municipal landfill. Researchers found seasonal variation in pollutant levels, with manganese and chromium as the dominant metals, and identified microplastics and pathogenic bacteria in the groundwater, highlighting the ongoing environmental and health risks from closed landfill sites.
Insight into the interactions between microplastics and heavy metals in agricultural soil solution: adsorption performance influenced by microplastic types
