Biochar has the potential to influence methanogenesis which is a key component of global carbon cycling. However, mechanisms governing biochar's on not well understood, especially its effects interspecies relationships between methanogens and anaerobic bacteria (e.g., Geobacteraceae). To understand how different types biochar methanogenesis, biochars derived from rice straw (RB), wood chips (WB), manure (MB) were added methanogenic enrichment culture system paddy soil. Compared nonbiochar control, RB MB additions accelerated remarkably, showing 10.7 12.3-folds higher methane production rate, respectively; while WB had little effect methanogenesis. Using Fourier transform infrared spectroscopy, X-ray photoelectron electrochemical methods, also redox-active properties or charging discharging capacities than WB, functional groups, mainly quinones, surface played an important role in facilitating Quantitative polymerase chain reaction results demonstrated that electronic syntrophy did exist Geobacteraceae. stimulate by direct electron transfer Our findings contribute better understanding feedstocks provide new evidence stimulating via biochar.

Sparking Anaerobic Digestion: Promoting Direct Interspecies Electron Transfer to Enhance Methane Production

iScience, Journal Year: 2020, Volume and Issue: 23(12), P. 101794 - 101794

Anaerobic digestion was one of the first bioenergy strategies developed, yet interactions microbial community that is responsible for production methane are still poorly understood. For example, it has only recently been recognized bacteria oxidize organic waste components can forge electrical connections with methane-producing microbes through biologically produced, protein-based, conductive circuits. This direct interspecies electron transfer (DIET) faster than exchange via diffusive carriers, such as H2. DIET also more resilient to perturbations increases in load inputs or toxic compounds. However, current digester practices rarely predominates. Improvements anaerobic associated addition electrically materials have attributed increased DIET, but experimental verification lacking. deficiency may soon be overcome improved understanding diversity capable which leading molecular tools determining extent DIET. Here we review microbiology suggest monitoring digesters, and propose approaches re-engineering design encourage
