Key genes of electron transfer, the nitrogen cycle and tetracycline removal in bioelectrochemical systems
Summary
This study used a soil microbial fuel cell system to demonstrate enhanced antibiotic and antibiotic resistance gene removal alongside improved nitrogen cycling, identifying key functional genes involved in electron transfer and biodegradation in antibiotic-contaminated soil.
The soil MFC promoted functional bacterial growth, increased functional gene abundance (including nitrogen cycling, electron transfer, and biodegradation), and facilitated antibiotic and ARG removal. Therefore, soil MFCs have expansive prospects in the remediation of antibiotic-contaminated soil. This study provides insight into the biodegradation mechanism at the gene level in soil bioelectrochemical remediation.

Decontamination and Ecological Restoration Performance of a Bioretention Cell-Microbial Fuel Cell under Multiple-Antibiotics Stress
Researchers designed a bioelectrically enhanced bioretention cell-microbial fuel cell (BRC-MFC) system to remove antibiotics from urban sewage, testing ofloxacin and tetracycline removal under multiple-antibiotic stress conditions and finding that the combined system leveraged plant absorption, filler adsorption, and microbial degradation synergistically for improved decontamination.
Effect of microplastics on the degradation of tetracycline in a soil microbial electric field
Researchers explored how microplastics affect the degradation of the antibiotic tetracycline in soil microbial electrochemical systems. The study found that polylactic acid and polyvinyl chloride microplastics enhanced the electrical output of soil systems and accelerated tetracycline breakdown, with microplastic surfaces acting as hotspots for antibiotic degradation due to their distinct microbial communities.

Researchers used microbial fuel cells — devices where bacteria break down pollutants and generate electricity — to simultaneously degrade the antibiotic chloramphenicol and PVC microplastics, finding that adding a bacterial communication molecule (quorum sensing signal 3OC8-HSL) increased antibiotic removal by 78% and power output by 81% by enriching specialized degrading bacteria.
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.
