Soil microbial fuel cells (MFCs) can remove antibiotics and antibiotic resistance genes (ARGs) simultaneously, but their removal mechanism is unclear. In this study, metagenomic analysis was employed to reveal the functional involved in degradation, electron transfer nitrogen cycle soil MFC.The results showed that MFC effectively removed tetracycline overlapping area of cathode anode, which 64% higher than control. The ARGs abundance increased by 14% after added (54% amplified belonged efflux pump genes), while decreased 17% MFC. Five potential degraders were identified, especially species Phenylobacterium zucineum, could secrete 4-hydroxyacetophenone monooxygenase encoded EC 1.14.13.84 catalyse deacylation or decarboxylation. Bacillus, Geobacter, Anaerolinea, Gemmatirosa kalamazoonesis Steroidobacter denitrificans since ubiquinone reductase (encoded 1.6.5.3), succinate dehydrogenase (EC 1.3.5.1), Coenzyme Q-cytochrome c 1.10.2.2), cytochrome-c oxidase 1.9.3.1) flavoprotein-ubiquinone oxidoreductase 1.5.5.1) served as complexes I, II, III, IV ubiquinone, respectively, accelerate transfer. Additionally, metabolism-related gene 16% support efficacy MFC, 1.7.5.1, coding mutual conversion between nitrite nitrate obviously improved.The promoted bacterial growth, (including cycling, transfer, biodegradation), facilitated ARG removal. Therefore, MFCs have expansive prospects remediation antibiotic-contaminated soil. This study provides insight into biodegradation at level bioelectrochemical remediation.

The mechanism of bioelectricity generation from organic wastes: soil/plant microbial fuel cells

Environmental Technology Reviews, Год журнала: 2023, Номер 13(1), С. 76 - 95

On a global perspective, organic wastes should be conceived as precious resource that can advantageous and in line with the waste-to-energy concept. Microbial fuel cell (MFC) is an up-and-coming bio-electrochemical technology developed to efficiently generate bioelectricity from various wastes, using microorganisms catalysts. Soil used produce electrical energy MFCs, which transform chemical soil compounds into electricity through catalysis by soil-derived microorganisms. In soil/plant microbial cells (SMFC/PMFC), behaves nutrient-rich anodic medium, of electrochemically active proton exchange membrane (PEM). addition advantages SMFC technology, it faces practical obstacles such low power current density. SMFC/PMFC systems understanding previous work describing their working methods theoretical foundations on they are built. Also, wide variety criteria likely limit performance identified giving brief description components. This study reviews components make up offers suggestions allow illuminate scientific locks continue effectiveness technology. review will provide discussion mechanism SMFC/PMFCs, researchers highlighted one renewable conversion systems, details about some available
