Biochar-induced quorum sensing enhances methane production by strengthening direct interspecies electron transfer.

Bioresource Technology
Biochar addition promotes direct interspecies electron transfer (DIET) between syntrophic bacteria and methanogens and increases the secretion of N-acyl homoserine lactones (AHLs); however, the specific role of AHLs in biochar-promoted DIET remains ...

Syntrophy Goes Electric: Direct Interspecies Electron Transfer

Annual Review of Microbiology, 2017
Direct interspecies electron transfer (DIET) has biogeochemical significance, and practical applications that rely on DIET or DIET-based aspects of microbial physiology are growing. Mechanisms for DIET have primarily been studied in defined cocultures in which Geobacter species are one of the DIET partners. Electrically conductive pili (e-pili) can be

Direct Interspecies Electron Transfer in Anaerobic Digestion: A Review

2015
Direct interspecies electrons transfer (DIET) is a syntrophic metabolism in which free electrons flow from one cell to another without being shuttled by reduced molecules such as molecular hydrogen or formate. As more and more microorganisms show a capacity for electron exchange, either to export or import them, it becomes obvious that DIET is a ...

Syntrophy and Interspecies Electron Transfer in Methanogenic Microbial Communities

Microbiology, 2020
Anaerobic digestion of municipal and other organic waste is a microbial process for conversion of complex organic substances to biogas (a renewable energy source) comprising a mixture of methane and CO2, and a stabilized sludge, which may be used as an organic fertilizer.
