Effects of co-loading of polyethylene microplastics and ciprofloxacin on the antibiotic degradation efficiency and microbial community structure in soil
Researchers studied how polyethylene microplastics and the antibiotic ciprofloxacin together affect soil microbial communities and antibiotic degradation. The study found that co-loading of microplastics with antibiotics altered microbial community structure and affected the rate of antibiotic degradation in soil, suggesting microplastic contamination may influence how soils process pharmaceutical pollutants.
Effects of microplastics on soil microbiome: The impacts of polymer type, shape, and concentration
Researchers examined how different microplastic polymer types, shapes, and concentrations affected soil bacterial communities, finding that these physical characteristics induced distinct shifts in soil microbiome composition and diversity.
Time-dependent effects of microplastics on soil bacteriome
Researchers studied how six common types of microplastics affect soil bacteria over time at realistic contamination levels. The effects were slow to appear due to the chemical stability of plastics, but over time, microplastics altered bacterial community structure and soil functions in ways that differed by plastic type. This matters because changes to soil bacteria can affect nutrient cycling and crop health, with potential downstream effects on food quality.
Assessment of the Impact of Ceftriaxone on the Functional Profile of Soil Microbiota Using Biolog EcoPlateTM
This is an ecotoxicology study examining how the antibiotic ceftriaxone affects soil microbial communities and earthworm gut microbiota; it is not a microplastics research paper.
Impact of Abiotic Stressors on Soil Microbial Communities: A Focus on Antibiotics and Their Interactions with Emerging Pollutants
This review examines how environmental stressors, especially antibiotics, affect the microbial communities that keep soil healthy and fertile. It also covers how antibiotics interact with other emerging pollutants like microplastics and heavy metals in soil. When microplastics carry antibiotics into soil, the combination can promote the spread of antibiotic-resistant bacteria, which is a growing concern for human health.
Bacterial dynamics of the plastisphere microbiome exposed to sub-lethal antibiotic pollution.
This study investigated how sub-lethal antibiotic concentrations in water interact with microplastic-associated biofilm communities (the plastisphere), finding that combined pollution alters bacterial dynamics and may contribute to antibiotic resistance selection in aquatic environments.
The impact of microplastic and sulfanilamide co-exposure on soil microbiota
This study investigated what happens when microplastics and the antibiotic sulfanilamide are present together in soil, finding that the combination significantly altered soil microbial communities compared to either pollutant alone. Both conventional polyethylene and biodegradable polylactic acid microplastics interacted with the antibiotic to change bacterial diversity and soil chemistry. The results show that microplastics and antibiotics in agricultural soil can have compounding effects on soil health, potentially affecting the crops grown in it.
Microbiome (rice soil)
Researchers investigated the effects of polyamide microplastics combined with common antimicrobials — sulfamethoxazole, ciprofloxacin, and triclosan — on bacterial communities in rice paddy soil microbiomes. The project aimed to characterize how co-exposure to microplastics and antibiotics alters soil microbial diversity and community composition in agricultural environments.
Impact of sulfamethoxazole on a riverine microbiome
Scientists studied how the antibiotic sulfamethoxazole affects the microbial community in a river, finding that even low concentrations shifted the balance of bacteria and promoted antibiotic resistance genes. This is relevant to the microplastic field because both antibiotics and microplastics promote antibiotic resistance when they co-occur in aquatic environments.
Microplastics increase soil microbial network complexity and trigger diversity-driven community assembly
Researchers found that microplastics in soil increased bacterial network complexity and shifted microbial community assembly in a diversity-dependent manner, with high-density polyethylene causing more harm to plant growth than polystyrene or polylactic acid particles.
The combined effect of microplastics and tetracycline on soil microbial communities and ARGs
Researchers studied how simultaneous exposure to microplastics and tetracycline affects soil microbial communities, finding that the combination disrupted microbial diversity, altered functional gene expression, and promoted horizontal transfer of antibiotic resistance genes beyond the effects of either pollutant alone.
The formation of specific bacterial communities contributes to the enrichment of antibiotic resistance genes in the soil plastisphere
Researchers used metagenomic approaches to study how microplastic surfaces in soil become enriched with antibiotic resistance genes through the formation of specific bacterial communities. The study tested three types of microplastics at two particle sizes and found that antibiotic resistance gene abundances significantly increased in the plastisphere compared to surrounding soil. Evidence indicates that microplastics in soil may serve as hotspots for the spread of antibiotic resistance.
Deciphering the Mechanisms Shaping the Plastisphere Microbiota in Soil
Researchers characterized bacterial communities colonizing biodegradable and conventional microplastics in soil, finding that polymer type and biodegradability shaped distinct plastisphere communities, with deterministic processes playing a stronger role in community assembly than in surrounding soil.
Impact of Microplastics on Ciprofloxacin Adsorption Dynamics and Mechanisms in Soil
Researchers investigated how microplastics affect the adsorption dynamics and mechanisms of ciprofloxacin (an antibiotic) in soil, finding that microplastics competed with soil particles for antibiotic binding and altered the overall fate and mobility of ciprofloxacin in the soil environment.
Influence of microplastics on the availability of antibiotics in soils
Researchers tested how three common types of microplastics affect the availability of antibiotics in different soil types. They found that microplastics significantly reduced the amount of antibiotics accessible in soil by providing extra binding sites and altering soil chemistry. The findings suggest that microplastic contamination in agricultural soils could change how antibiotics move through the environment.
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.
The effects of single and combined pollution of PE microplastics and antibiotics in soil on wheat (Triticum aestivum L.) seedlings
This study examined the combined effects of polyethylene microplastics and antibiotic exposure on soil organisms, finding that mixture exposure altered soil microbial community structure and promoted antibiotic resistance gene abundance more than either stressor alone. Co-exposure to microplastics and antibiotics poses compounded risks for soil microbiomes.
Microplastics inhibit oxytetracycline degradation in soils: Insights into biofilm-enhanced adsorption and microbial community shifts
Researchers examined how polyethylene and polylactic acid microplastics affect oxytetracycline degradation in organic fertilizer-amended paddy soil, finding that both plastic types significantly inhibited antibiotic degradation by lowering degradation rates 11.1-20.2%. Biofilm formation on microplastic surfaces enhanced oxytetracycline adsorption and shifted microbial community composition, reducing the abundance of antibiotic-degrading microorganisms.

This study sampled agricultural soils with varying degrees of microplastic contamination to assess effects on microbial diversity, abundance, and enzymatic activity, finding that higher microplastic concentrations reduced microbial diversity and suppressed nutrient-cycling enzyme activity.
Succession of soil bacterial communities and network patterns in response to conventional and biodegradable microplastics: A microcosmic study in Mollisol
Using a soil microcosm experiment, researchers compared how conventional polyethylene and biodegradable microplastics affected soil bacterial communities over 90 days across four dosages. Biodegradable microplastics induced greater community dissimilarity from controls and tended to enrich environmentally beneficial taxa, while conventional polyethylene promoted potentially hazardous bacteria.
Effects of hexabromocyclododecane and polyethylene microplastics on soil bacterial communities
Researchers examined how the flame retardant hexabromocyclododecane and polyethylene microplastics, both separately and combined, affect bacterial communities in agricultural soil over four months. They found that microplastics and the combined exposure significantly altered bacterial diversity, while the flame retardant alone had less impact at low concentrations. The study suggests that the interaction between microplastics and chemical pollutants in soil can reshape microbial communities in ways that may affect soil function.
