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
