ClearEffect of microplastics on soil microbial community and microbial degradation of microplastics in soil: A review
This review examines how microplastics affect soil microbial communities and the potential for microbes to degrade plastic particles in soil environments. The study highlights that soil acts as a major sink for microplastics from sources like sewage sludge, agricultural mulch, and wastewater, and identifies key knowledge gaps including the need for better monitoring of microplastic sources and exploration of microbial biodegradation potential.

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.
[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.
Potential strategies for bioremediation of microplastic contaminated soil
Researchers reviewed emerging bioremediation strategies for removing microplastics from contaminated soil, highlighting the roles of plants, root-zone microbes, soil animals like earthworms, and specialized bacteria and fungi that can use enzymes to break down plastic polymers into harmless compounds. While genetic engineering of microbes shows promise for accelerating degradation, the review notes that real-world application at scale still requires significant research and development.
Evidence on Potential Bioremediation of Microplastics from Soil Environment around the World
This review examines evidence for bioremediation of microplastics from soil environments, evaluating how plants, bacteria, fungi, and other organisms can help remove or break down plastic particles in terrestrial ecosystems. While soil is a primary sink for microplastics, biological approaches to soil cleanup remain underdeveloped compared to aquatic bioremediation research.
Bioremediation of Microplastic Wastes in Soil
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.
Systematical review of interactions between microplastics and microorganisms in the soil environment
This review explores interactions between microplastics and microorganisms in soil environments. Researchers found that microplastics pose a threat to the survival and reproduction of soil microbiota, but that soil microorganisms also show potential for degrading and mineralizing microplastic particles, suggesting possible biological pathways for microplastic remediation in terrestrial ecosystems.
The plastic and microplastic waste menace and bacterial biodegradation for sustainable environmental clean-up a review
This review examined bacterial biodegradation of plastic and microplastic waste, covering key microbial species, enzymatic mechanisms, and biotechnological approaches being developed for sustainable environmental cleanup of plastic pollution.
The impact of microplastics on soil ecosystems: A review
This review examines how microplastics accumulate in soil from sources like sewage sludge, agricultural plastic mulch, and wastewater, and how they affect soil ecosystems. Evidence indicates that microplastics alter soil physical and chemical properties, disrupt microbial communities and enzyme activity, and can harm plant growth and soil organisms. The authors highlight that soil microplastic pollution has received far less research attention compared to aquatic environments, despite its potential consequences for agriculture and food safety.
Interaction effects and mechanisms of microorganisms and microplastics in soil environment
This review examines how microplastics and soil microorganisms interact: microplastics disrupt soil structure, reduce water retention, and impede plant root growth, while certain bacteria and fungi can colonize and partially degrade plastic particles through a multi-step process involving colonization, fragmentation, assimilation, and mineralization. Different polymer types (PE, PP, PS, PVC, PET) attract different microbial communities, and factors like temperature, moisture, and plastic additives affect degradation rates. Understanding these interactions is key to assessing long-term soil health impacts and developing microbial strategies to reduce plastic accumulation in agricultural soils.
What Do We Know About the Effects of Microplastics on Soil?
This review examines the effects of microplastics on soil ecosystems, covering how mulching, wastewater irrigation, sludge application, and atmospheric deposition introduce microplastics to soil, where they alter physicochemical properties, affect microbial communities, and carry co-pollutants.

Researchers identified specific bacterial genera capable of degrading multiple types of plastic across different environments including landfill soil, sewage sludge, and river water. They found that certain bacteria, such as Pseudomonas and Bacillus species, consistently appeared as effective plastic degraders regardless of the environment. The study suggests that these universal plastic-degrading bacteria could be valuable candidates for developing bioremediation strategies to address plastic pollution.

Biodegradation by indigenous soil bacteria could offer a more environmentally friendly alternative to landfilling or incineration of plastic waste.

The Role of Soil Microorganisms in Microplastic Biodegradation: Mechanisms, Carbon Preferences, and Ecological Impacts
This review examines how soil microorganisms interact with microplastics and attempt to biodegrade them, finding that despite plastics being carbon-based, their unique chemical structures prevent microbes from using them the same way they use natural organic matter. Soil carbon availability affects which microbes preferentially colonize and partially break down plastic particles, but full assimilation remains limited. Understanding microbial degradation pathways is important for assessing how long microplastics persist in soils and for developing bioremediation strategies.
