Integrating microbial electrolysis cells and anaerobic digestion (MEC-AD) improves upon conventional for biomethane production due to the in-situ provision of electrochemically produced reducing power (such as hydrogen). However, electron transfer behaviour at microbe-electrode interface remains unclear. This study assessed micro-scale modification a carbonaceous bioelectrode, leading an enhanced local electric field, which was postulated stimulate electro-methanogenesis. The effectiveness incorporating electro-conductive biochar enhance interspecies also evaluated its potential boost production. findings revealed notable increase in yield methane content within biogas MEC-AD system, with improvements 96.8 % 32.5 %, respectively, compared when co-digesting grass silage cattle slurry. enhancement ascribed accumulation charges intensified field on surface etched biocathode, thereby facilitating interfacial transfer. Incorporating 10 g/L resulted 7.9 digestion. Overall, heightened energy by system (featuring modified graphite cathode) 6.5-fold additional electrical input. underscores catalytic significance electricity AD system.

Mitigation of Triclocarban Inhibition in Microbial Electrolysis Cell-Assisted Anaerobic Digestion

Environmental Science & Technology, Год журнала: 2024, Номер 58(21), С. 9272 - 9282

Triclocarban (TCC), as a widely used antimicrobial agent, is accumulated in waste activated sludge at high level and inhibits the subsequent anaerobic digestion of sludge. This study, for first time, investigated effectiveness microbial electrolysis cell-assisted (MEC-AD) mitigating inhibition TCC to methane production. Experimental results showed that 20 mg/L inhibited disintegration, hydrolysis, acidogenesis, methanogenesis processes finally reduced production from traditional by 19.1%. Molecular docking revealed potential inactivation binding key enzymes these processes. However, MEC-AD with 0.6 0.8 V external voltages achieved much higher controlled less than 5.8%. systems was adsorbed humic substances degraded dichlorocarbanilide, leading certain detoxification effect. Methanogenic activities were increased systems, accompanied complete VFA consumption. Moreover, applied voltage promoted cell apoptosis disintegration release biodegradable organics. Metagenomic analysis resistance electrode biofilms enriching functional microorganisms (syntrophic VFA-oxidizing electroactive bacteria hydrogenotrophic methanogens), acidification pathways, multidrug efflux pumps, SOS response.
