ClearCo-metabolic breakdown of LDPE microplastics in PGPR-Assisted phytoremediation of hydrocarbon-contaminated soil
Low-density polyethylene (LDPE) microplastics were degraded through a co-metabolic process by plant growth-promoting rhizobacteria (PGPR), suggesting that beneficial soil bacteria can be harnessed to break down plastic in the root zone. The approach offers a bioremediation strategy that simultaneously improves soil microbiome function.

Researchers conducted a pot experiment to evaluate the petroleum hydrocarbon degradation capability of bacterium strain TDYN1 in soil and to assess how microplastics affect the bioremediation process.

Biodegradation of polyethylene terephthalate microplastics by Paenibacillus naphthalenovorans PETKKU2: Response surface optimization and genomic evidence for an alternative degradation mechanism
This study identified a soil bacterium, Paenibacillus naphthalenovorans PETKKU2, isolated from a Thai landfill, as capable of degrading PET microplastics and achieving nearly 10% weight loss over 35 days under optimized conditions — through a degradation pathway distinct from the well-known PETase enzyme route. Surface analysis confirmed progressive erosion and chemical changes in the plastic. Discovering new microbial pathways for PET degradation is important for developing biological recycling and remediation strategies for one of the world's most common plastic pollutants.
Effects of biodegradable microplastics coexistence with biochars produced at low and high temperatures on bacterial community structure and phenanthrene degradation in soil
Researchers investigated how biodegradable microplastics interact with biochar in soil to affect bacterial communities and pollutant degradation. The study found that the coexistence of PBAT microplastics and biochar significantly altered soil microbial structure and influenced the degradation of phenanthrene, suggesting complex interactions between these increasingly common soil amendments.
Effects of biodegradable and non-biodegradable microplastics on bacterial community and PAHs natural attenuation in agricultural soils
Researchers found that biodegradable and non-biodegradable microplastics differently affect soil bacterial communities and the natural attenuation of polycyclic aromatic hydrocarbons in agricultural soils, with biodegradable plastics sometimes enhancing microbial activity while conventional plastics inhibited PAH degradation.
Isolation of a soil bacterium for remediation of polyurethane and low-density polyethylene: a promising tool towards sustainable cleanup of the environment.
A soil bacterium tentatively classified in the Pseudomonas genus was found to biodegrade both polyurethane and low-density polyethylene plastics. The discovery of a single bacterial strain capable of degrading two different types of plastic is a step toward developing practical microbial tools for plastic waste remediation.
Microplastics reduced bioavailability and altered toxicity of phenanthrene to maize (Zea mays L.) through modulating rhizosphere microbial community and maize growth
Researchers studied how microplastics affect the behavior of phenanthrene, a common soil pollutant, in maize-growing soil. They found that microplastics reduced the amount of phenanthrene absorbed by the plants while also changing the microbial communities around the roots. The study suggests that microplastics in agricultural soil can alter how other pollutants interact with crops, sometimes reducing their uptake but also shifting soil ecology in complex ways.
