미생물-전기분해 기반 미량 오염물질 (CECs)의 환경 독성 제거 : 메커니즘, 분해 경로 및 독성 평가 = Environmental Detoxification of Contaminants of Emergin Concern (CECs) using Bio-electrodegradation: Mechanism, Pathway an Toxicity assessment

다국어 초록 (Multilingual Abstract)

This study presents a consolidated evaluation of bio-electrodegradation as advanced, sustainable platforms for the degradation of diverse environmental contaminants, including pharmaceuticals (carbamazepine, norfloxacin, amoxicillin), pesticides (chlorpyrifos), and industrial microplastic-derived pollutants (benzothiazole). Across all studies, bio-electrodegradation consistently outperformed conventional biodegradation and electrodegradation processes, achieving near-complete removal efficiencies ranging from 90-98% under optimized conditions. The synergistic integration of microbial metabolism with electro stimulation enhanced key enzymatic activities, such as esterase, dehydrogenase, peroxidase, and dioxygenases, facilitating complete mineralization without generating toxic intermediates. HPLC–MS/MS analyses confirmed thorough degradation pathways, while multi-tier ecotoxicological assessments (microbial, phytotoxicity, cytotoxicity, and invertebrate bioassays) validated the non-toxic nature of bio-electrodegradation samples. Microbial community and soil health analyses revealed restored ecological balance and biocompatibility following treatment. Collectively, these findings establish bio-electrodegradation as a robust, eco-friendly, and scalable remediation technology capable of addressing multiple classes of contaminants while mitigating ecological risks. The system’s potential for integration underscores its promise for real-world wastewater treatment and sustainable environmental management.
