Rhizosphere microbiome metagenomics in PGPR-mediated alleviation of combined stress from polypropylene microplastics and Cd in hybrid Pennisetum
Researchers found that beneficial soil bacteria (PGPR) can help plants cope with the combined stress of polypropylene microplastics and the toxic heavy metal cadmium.

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.
Plant growth-promoting bacteria modulate gene expression and induce antioxidant tolerance to alleviate synergistic toxicity from combined microplastic and Cd pollution in sorghum
Scientists found that a beneficial soil bacterium (Bacillus sp. SL-413) can help protect sorghum plants from the combined toxic effects of microplastics and cadmium, a heavy metal. The bacterium boosted plant growth, reduced harmful reactive oxygen species by up to 27%, and reactivated genes that the pollution had shut down. This research points to a nature-based solution for helping food crops survive in microplastic-contaminated soil.

This review examines how plant growth-promoting bacteria (PGPB) can be used to remediate antibiotic-contaminated agricultural soils, covering the diversity of bacterial mechanisms and ecological risks. It also discusses how microplastics in soil interact with antibiotic persistence and resistance gene spread.

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.

Accelerating phytoremediation of degraded agricultural soils utilizing rhizobacteria and endophytes: a review
This review examines how beneficial soil bacteria and fungi can help plants clean up contaminated agricultural soils, including those polluted by plastic mulch residues, pesticides, and heavy metals. Microbial-assisted phytoremediation is presented as a promising low-cost approach for restoring degraded farmland.
Susceptibility of Cd availability in microplastics contaminated paddy soil: Influence of ferric minerals and sulfate reduction
When microplastics and cadmium contaminate paddy soil together — a common situation in agricultural areas — microplastics increase the availability of cadmium to plants, raising the risk of cadmium uptake into food crops like rice. The mechanism involves microplastics releasing dissolved organic matter that disrupts iron mineral cycling and promotes sulfate-reducing bacteria, which in turn mobilize cadmium from soil particles. These findings highlight that microplastic pollution in farmland does not act alone — it can amplify the toxicity of co-occurring heavy metal contaminants.
Insights on Immobilization of Cd Contamination in Soil: Synergic Impacts of Water Management and Bauxite Residue
Researchers tested whether combining flooding with bauxite residue or lime could reduce the availability of toxic cadmium in contaminated soil. Both combined treatments raised soil pH and increased the proportion of cadmium locked into stable, residual forms while decreasing the easily exchangeable fraction. The bauxite residue treatment proved slightly more effective at immobilizing cadmium, offering a potential soil remediation strategy for heavy metal-contaminated agricultural land.
The Effects of Coexisting Elements (Zn and Ni) on Cd Accumulation and Rhizosphere Bacterial Community in the Soil-Tomato System

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.

Researchers found that adding biochar (a charcoal-like soil additive) to soil contaminated with microplastics helped improve plant growth by restoring phosphorus cycling. The microplastics disrupted soil microbe communities, but biochar treatment shifted these communities in beneficial ways. This suggests biochar could be a practical tool for farming in soils contaminated with plastic pollution.
Phosphorus fertiliser application mitigates the negative effects of microplastic on soil microbes and rice growth
Researchers found that adding phosphorus fertilizer to soil contaminated with microplastics helped counteract the negative effects of the plastics on rice growth and soil microbial communities.
