Plant growth-promoting bacteria improve the Cd phytoremediation efficiency of soils contaminated with PE–Cd complex pollution by influencing the rhizosphere microbiome of sorghum
Researchers found that adding beneficial bacteria to soil contaminated with both polyethylene microplastics and the toxic metal cadmium helped sorghum plants grow larger and absorb more cadmium from the soil, improving cleanup potential. This approach matters for food safety because using plants and bacteria to remove combined microplastic-heavy metal pollution from farmland could reduce the amount of these contaminants that enter the food supply.
Beneficial microbial consortia effectively alleviated plant stress caused by the synergistic toxicity of microplastics and cadmium
Researchers found that combined pollution from microplastics (PVC) and the heavy metal cadmium creates a toxic effect in soil that is worse than either pollutant alone. However, applying beneficial bacteria to contaminated soil helped plants grow better and restored soil nutrients. These findings suggest that probiotic-like bacteria could help repair farmland damaged by microplastic and heavy metal pollution.

Researchers found that beneficial soil bacteria (PGPR) can help plants cope with the combined stress of polypropylene microplastics and the toxic heavy metal cadmium. The bacteria improved plant growth by 8-42% under contaminated conditions by reshaping the microbial community around plant roots. This study offers a potential strategy for maintaining crop productivity in farmland contaminated with both microplastics and heavy metals.
Effects of combined microplastic and cadmium pollution on sorghum growth, Cd accumulation, and rhizosphere microbial functions
Researchers examined how different types and sizes of microplastics interact with cadmium, a toxic heavy metal, to affect sorghum growth and soil microbes. They found that the combined pollution generally increased plant stress and cadmium uptake, with effects varying by plastic type, particle size, and concentration. The study also revealed that the pollution mixture significantly altered soil bacterial communities and key metabolic pathways involved in nutrient cycling.

A transcriptomics study examined how the plant growth-promoting bacterium VY-1 alleviates combined stress from microplastics and heavy metals in sorghum grown in hydroponic conditions. Inoculation with VY-1 improved biomass and reduced heavy metal accumulation in sorghum, with gene expression analysis revealing the underlying protective mechanisms.
Regulatory Mechanisms of Plant Growth-Promoting Bacteria in Alleviating Microplastic and Heavy Metal Combined Pollution: Insights from Plant Growth and Metagenomic Analysis
Researchers used metagenomic sequencing to investigate how plant growth-promoting bacteria (PGPB) mitigate the combined toxicity of microplastics and heavy metals on plant growth. PGPB inoculation restored rhizosphere microbial function and reduced plant stress, revealing microbiome-mediated mechanisms for alleviating mixed pollutant toxicity.
Responses of Sorghum Growth and Rhizosphere–Plastisphere Microbiomes to Cadmium and Polypropylene Microplastic Co-Contamination
Researchers examined how combined cadmium and polypropylene microplastic contamination affects sorghum growth and the bacterial communities in both rhizosphere soil and on the plastic surfaces. They found that co-contamination inhibited sorghum development more severely than either pollutant alone, and the bacterial community on the plastic surface was structurally simpler with lower diversity than in surrounding soil. The study suggests that microplastics in contaminated soils can serve as distinct microbial habitats that differ significantly from the native soil environment.
Combined effects of heavy metals and microplastics on maize grown in acid and alkaline soils inoculated with plant growth promoting rhizobacteria
Researchers grew maize in soils contaminated with combinations of biodegradable (PLA) and conventional (LDPE) microplastics and heavy metals (Pb, Cd, Zn, Ni) in both acid and alkaline soils, with and without plant growth-promoting bacteria. The combined microplastic-heavy metal contamination reduced growth more than either stressor alone, while bacterial inoculants partially mitigated the damage in alkaline soils.

Researchers found that inoculating soybean plants with a combination of mycorrhizal fungi and beneficial bacteria helped protect them from microplastic-induced stress, improving biomass, seed quality, antioxidant defenses, and hormone balance. The study suggests that soil microbe communities could be harnessed as a sustainable strategy to help crops cope with growing microplastic contamination in agricultural soils.
Interactive effects of microplastics and cadmium on soil properties, microbial communities and bok choy growth
Researchers grew bok choy in soil amended with polyethylene microplastics (0.5-2% by weight) and cadmium to assess interactive effects on soil properties, microbial communities, and plant growth. Combined exposure produced distinct synergistic and antagonistic interactions compared to either pollutant alone, altering soil enzyme activity, bacterial diversity, and plant metal uptake.
Effects of polyethylene microplastics and cadmium co-contamination on the soybean-soil system: Integrated metabolic and rhizosphere microbial mechanisms
Researchers investigated how polyethylene microplastics and cadmium interact in soybean-soil systems and found that specific microplastic concentrations enhanced cadmium accumulation in roots under moderate contamination. Higher microplastic levels reduced beneficial soil bacteria like Sphingomonas and Bradyrhizobium and suppressed nitrogen-cycling functions. The study demonstrates that microplastics fundamentally alter heavy metal behavior through interconnected plant-metabolite-microbe interactions in agricultural soils.
Microplastics alter cadmium accumulation in different soil-plant systems: Revealing the crucial roles of soil bacteria and metabolism
A study found that microplastics in soil can change how much cadmium, a toxic heavy metal, is absorbed by food crops, with the effects varying depending on soil type and the amount of plastic present. By altering soil chemistry and bacterial communities, microplastics reshape how pollutants move through farmland and into the food we eat.
Individual and Combined Effects of Nanoplastics and Cadmium on the Rhizosphere Bacterial Community of Sedum alfredii Hance
When polystyrene nanoplastics and cadmium co-occur in soil, they act synergistically to disrupt the bacterial community around plant roots (rhizosphere), reducing the diversity of beneficial bacteria by more than what either pollutant does alone. High concentrations of nanoplastics combined with cadmium significantly increased the availability of cadmium in soil by 4%, potentially increasing uptake by plants. This matters for both food safety — since Sedum alfredii is used in phytoremediation of heavy-metal-contaminated sites — and for understanding how combined pollution stresses affect soil health.

Researchers tested whether adding bacteria and biochar (a charcoal-like material) to microplastic-contaminated paddy soil could help rice plants recover, finding that the combined treatment increased shoot weight by over 100% and dramatically improved nutrient uptake genes. The treatment also enriched beneficial soil microbes and reduced oxidative stress in rice, offering a promising strategy for restoring agricultural soils polluted with microplastics.

Researchers tested whether beneficial soil fungi and bacteria could help peanut plants cope with combined contamination from cadmium and microplastics. They found that the microbial treatment effectively trapped cadmium in the plant roots, preventing it from moving into the shoots and edible parts. The study suggests that harnessing natural soil microbes could be a practical strategy for growing safer food in polluted farmland.

Researchers investigated how beneficial soil fungi called arbuscular mycorrhizal fungi can help maize plants resist cadmium toxicity in soils contaminated with both microplastics and heavy metals. They found that high concentrations of polyethylene microplastics worsened cadmium toxicity, but inoculation with mycorrhizal fungi significantly improved plant growth, nutrient uptake, and photosynthesis. The study suggests that these fungi could serve as a biological tool for managing crop health in soils with combined microplastic and heavy metal contamination.
Combined effects of microplastics and cadmium on the soil-plant system: Phytotoxicity, Cd accumulation and microbial activity
Researchers tested how different microplastic types combined with cadmium affect plant growth and soil health. Aged and biodegradable microplastics increased cadmium uptake in mustard greens more than fresh conventional plastics did. The study also found that microplastics altered soil microbial activity, suggesting that plastic pollution in farmland could change how plants absorb toxic metals from contaminated soil.
Effects of polyethylene microplastics on cadmium accumulation in Solanum nigrum L.: A study involving microbial communities and metabolomics profiles
This study found that polyethylene microplastics in soil reduced the ability of a plant known for cleaning up cadmium contamination to absorb the toxic metal. The microplastics changed the soil's microbial community and altered the plant's metabolism in ways that disrupted its natural heavy metal uptake process. This is important because it suggests microplastic pollution in farmland could interfere with natural and engineered soil cleanup strategies for heavy metals.
