Microbiome (rice soil)
AI summary Read the abstract
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.
This project aimed to study the effects of polyamide microplastics and common antimicrobials (sulfamethoxazole, ciprofloxacin, and triclosan) on soil bacterial communities.

Polyamide Microplastics and Common Antimicrobials in Treated Wastewater: Unveiling their Effects on Rice Plant Growth and Soil Microbiome dynamics
AI summary Read the abstract
Researchers exposed rice plants to polyamide microplastics and three antimicrobials — sulfamethoxazole, ciprofloxacin, and triclosan — individually and in combination, finding that microplastics enhanced uptake of two antimicrobials into plant tissues and drove 100–200-fold increases in soil antibiotic resistance genes, revealing compounding risks when these co-contaminants interact in agricultural soils.
The impact of microplastic and sulfanilamide co-exposure on soil microbiota
AI summary Read the abstract
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.
Integrated Effects of Polyamide Microplastics and Three Abundant Antimicrobials and Reclaimed Water On The Growth of Lettuce and Soil Bacterial Communities
AI summary Read the abstract
Researchers investigated the combined effects of polyamide microplastics and three common antimicrobials -- sulfamethoxazole, ciprofloxacin, and triclosan -- alongside reclaimed water irrigation on lettuce growth and soil bacterial community composition. The study examined how simultaneous exposure to microplastics and pharmaceutical contaminants alters soil microbial ecology in agricultural settings.
Effects of co-loading of polyethylene microplastics and ciprofloxacin on the antibiotic degradation efficiency and microbial community structure in soil
AI summary Read the abstract
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.
Metagenomic analysis of florfenicol and microplastics effects on microbial function and antibiotic resistome in rice seedling rhizosphere soil
AI summary Read the abstract
When researchers combined a common livestock antibiotic with microplastics in rice paddy soil, they found the mix made things worse than antibiotics alone, six different multi-drug-resistant, disease-causing bacteria showed up, compared to none in untreated soil. This suggests microplastics can team up with antibiotic pollution to help create more dangerous "superbugs" in the soil where our food grows, a concerning finding for food safety and the ongoing fight against antibiotic resistance.
