Methane (CH4) is the second most damaging greenhouse gas by absolute amounts released. Many globally distributed methane sources are of human origin, representing a significant untapped potential for capture and on-site conversion into electricity or 'higher value' chemicals. This study systematically quantitatively analyzes anaerobic oxidation (AOM) in microbial fuel cells (MFCs) generating electric power as well AOM bioreactors producing value-added The maximum performance such systems currently unknown. Based on biophysical arguments, densities 10 kW/m3 more should be achievable, Coulombic, carbon conversion, energy efficiency could reach 90%. Such much higher than what usually predicted. MFC approach promises efficiency, scalability, cost-effectiveness, easier distribution compared to existing chemical plants aerobic biological approaches. Yet achieving this requires integrated advancement different technologies. analysis provides an accessible primer necessary interdisciplinary research effort, discusses recent enabling biotechnological advancements, open questions corresponding R&D pathways, where enzyme synthetic consortia engineering, microfluidic technologies, membrane electrode materials, modular system integration, optimization technology will likely critical. In conclusion, very promising limits estimated here show, if realized at scale, impact green-house reduction sustainable, on-demand (fuel) production achieved; also aid rational design other reactions.

Anaerobic methanotrophic archaea (ANME) belonging to the family Methanoperedenaceae are crucial for global carbon cycle and different biogeochemical processes, owing their metabolic versatility couple anaerobic oxidation of methane (AOM) with electron acceptors. A universal feature is abundant genes encoded in genomes associated extracellular transfer (EET) pathways. Candidatus. 'Methanoperedens manganicus', an archaeon Methanoperedenaceae, was recently enriched a bioreactor performing AOM coupled Mn (IV) reduction. Using this EET-capable ANME, we tested hypothesis study that ANME can catalyse humic-dependent growth. two-year incubation showed activity be sustained by Ca. 'M. manganicus' consortium fed only humic acids methane. An isotopic mass balance batch test confirmed observed reduction acids. The increase relative abundance total population microbial community suggested grow on observation led subsequent could used as shuttle mediate EET dissimilatory manganicus'. We adding dominated-culture, which rate doubled addition X-ray photoelectron spectroscopy (XPS) quinone moieties were consumed when worked acceptors while remaining stable functioning transfer. results our suggest may serve shuttles allow access more through long-range EET.
