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.
Effect 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.
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.
Microplastics and soil microbiomes
This review examines the two-way relationship between microplastics and soil microbiomes: how microplastics alter microbial community structure and function, and how soil microbes in turn affect the behavior of microplastics. Researchers found that microplastics can shift microbial communities and disrupt key ecosystem processes like nutrient cycling. The study also discusses how certain soil microbes may enhance the degradation of microplastics, pointing to potential natural remediation pathways.

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.
Bioremediation of Soil Microplastics: Categories and Mechanisms
This review examines biological approaches to breaking down microplastics in soil, including the use of bacteria, fungi, and enzymes. Researchers found that certain microorganisms can partially degrade various plastic polymers, though the process is slow and influenced by plastic type, environmental conditions, and microbial community composition.
Microplastic effects on soil organic matter dynamics and bacterial communities under contrasting soil environments
Researchers compared microplastic effects on soil organic matter dynamics and bacterial communities across contrasting soil environments, finding that the type of microplastic polymer and soil conditions together determine whether microbial activity and carbon cycling are stimulated or suppressed.
Soils in distress: The impacts and ecological risks of (micro)plastic pollution in the terrestrial environment
This review examines how microplastics affect soil ecosystems, including their transport into soils, changes they undergo in the environment, and their interactions with soil organisms. The effects depend heavily on the type, shape, size, and amount of plastic particles present. Understanding these impacts is important because soil contamination with microplastics can affect food production and ultimately human exposure through the food chain.
Microplastics in soils: Production, behavior process, impact on soil organisms, and related toxicity mechanisms
This review examines how microplastics enter and persist in soils, covering their sources from agricultural plastics, irrigation water, and atmospheric deposition. Researchers found that microplastics can alter soil structure, affect nutrient cycling, and harm soil organisms like earthworms and microbes. The study highlights significant gaps in understanding the long-term ecological consequences of soil microplastic contamination.
Effects of microplastics on soil microorganisms and microbial functions in nutrients and carbon cycling – A review
This review examines how microplastics in soil alter the communities of bacteria and fungi that are essential for recycling nutrients like nitrogen, phosphorus, and carbon. Microplastics can increase certain beneficial bacteria but decrease others that are important for soil fertility, and they also carry toxic chemicals that further disrupt microbial life. The authors note that most studies are short-term lab experiments, and long-term field studies are needed to understand real-world impacts.
Effects of microplastics on soil physical, chemical and biological properties
This review examines how microplastics affect soil health, covering their impact on the physical structure, chemical composition, and biological communities of soil ecosystems. Microplastics can alter soil water retention, change nutrient cycling, and harm soil organisms from earthworms to microbes. Since agricultural soils are a major reservoir of microplastics, these changes could affect crop growth and food quality, creating an indirect pathway for microplastic-related harm to human health.

The research supports sustainable farming practices that could help soils better cope with microplastic contamination.
The Spatiotemporal Successions of Bacterial and Fungal Plastisphere Communities and Their Effects on Microplastic Degradation in Soil Ecosystems
Researchers tracked how bacterial and fungal communities colonize microplastic surfaces in soil over time, finding that the surrounding soil type had the strongest influence on which microbes grew on the plastics. The microbial communities on microplastics were less diverse and less stable than those in the surrounding soil, but they attracted microbes with a higher capacity to break down organic carbon. The study suggests that microplastic surfaces become hotspots for carbon metabolism in soil ecosystems.
Soil microorganisms play an important role in the detrimental impact of biodegradable microplastics on plants
Researchers found that biodegradable microplastics harmed vegetable crop growth by disrupting the soil microbial community rather than through direct contact with the plants. When soil microorganisms were suppressed, the negative effects of the biodegradable microplastics on plant growth were also reduced. The study suggests that soil bacteria and fungi play a key role in mediating the harmful impacts of biodegradable plastics on agricultural crops.
Time-resolved colonization patterns of bacteria and fungi on polystyrene microplastics in floodplain soils
Scientists studied how bacteria and fungi grow on tiny plastic particles (microplastics) buried in soil over several months. They found that these microbes form films on the plastic surfaces and some types can actually break down the plastic particles. This matters because microplastics are everywhere in our environment, and understanding how soil microbes interact with them could help us learn whether these plastics break down naturally or accumulate in ways that might affect our food and water.
