Syntrophy Goes Electric: Direct Interspecies Electron Transfer

Annual Review of Microbiology, Journal Year: 2017, Volume and Issue: 71(1), P. 643 - 664

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 have primarily been studied in defined cocultures which Geobacter species one the partners. Electrically conductive pili (e-pili) can be an important electrical conduit DIET. However, there may instances contacts made between transport proteins associated with outer membranes Alternatively, partners plug into carbon materials, such as granular activated carbon, cloth, biochar, long-range exchange without need e-pili. Magnetite promotes DIET, possibly by acting a substitute outer-surface c-type cytochromes. is primary mode some anaerobic digesters converting wastes to methane. Promoting materials shows promise stabilizing accelerating methane production digesters, permitting higher organic loading rates. Various lines evidence suggest terrestrial wetlands, source atmospheric also role oxidation coupled sulfate reduction, control releases. The finding serve electrons photosynthesis further broadens its potential environmental significance.

Methane Production and Conductive Materials: A Critical Review

Environmental Science & Technology, Journal Year: 2018, Volume and Issue: 52(18), P. 10241 - 10253

Published: Aug. 17, 2018

Conductive materials (CM) have been extensively reported to enhance methane production in anaerobic digestion processes. The occurrence of direct interspecies electron transfer (DIET) microbial communities, as an alternative or complementary indirect (via hydrogen formate), is the main explanation given justify improvement production. Not disregarding that DIET can be promoted presence certain CM, it surely does not explain all observations. In fact, methanogenic environments was only unequivocally demonstrated cocultures Geobacter metallireducens with Methanosaeta harundinacea Methanosarcina barkeri and frequently sp. are detected improved driven systems. Furthermore, conductive carbon nanotubes were shown accelerate activity methanogens growing pure cultures, where expected occur, hydrogenotrophic ubiquitous full-scale digesters treating for example brewery wastewaters, indicating important mechanism those This paper presents overview effect several iron-based carbon-based CM bioengineered systems, focusing on communities' changes. Control assays, fundamental elements support major conclusions experiments, critically revised discussed.
