Direct Interspecies Electron Transfer Between Archaea and Bacteria
2017Archaea and bacteria living in syntrophic consortia take advantage of the metabolic abilities of their syntrophic partners to overcome energetic barriers and break down compounds that they cannot digest by themselves. Methanogenesis and anaerobic oxidization of methane (AOM) are main processes involved in syntrophic consortia.

Transition metal compounds have been widely used to enhance the anaerobic digestion (AD) performance, while the role of transition metal compounds in enhancing AD performance remains unclarified. In this work, the function of transition metal oxide accelerants (tantalum oxide, niobium oxide, hafnium oxide, and tungsten oxide) in enhanced AD systems was

[Research advances in direct interspecies electron transfer within microbes].
Ying yong sheng tai xue bao = The journal of applied ecology, 2021Hydrogen and formic acid have been considered as the intermediate electron transporters among microbes for a long time. In recent years, however, it has been found that direct interspecies electron transfer (DIET) might be an alternative beyond hydrogen/formic acid to transfer electron among microbes.

Direct interspecies electron transfer (DIET) via electrically conductive pili (e-pili) and c-type cytochrome between acetogens and methanogens has been proposed as an essential pathway for methane production. Supplements of conductive materials have been extensively found to promote methane production in microbial anaerobic treatment systems.

The syntrophic photosynthesis via direct interspecies electron transfer (DIET) between Geobacter sulfurreducens and Prosthecochloris aestuarii has opened a new paradigm of microbial phototrophy. However, it is still unknown whether this photosynthetic DIET can be mediated by an electrical conductor. Here we report first the photosynthetic DIET in a two-

Anaerobic digestion (AD) is a microbial process that produces renewable energy in the form of methane by treating organic waste and high-strength wastewater. Recent studies have demonstrated that conductive materials can promote direct interspecies electron transfer (DIET) between exoelectrogenic bacteria and methanogenic archaea.

Ethanol pre-fermentation of food waste effectively alleviates acidification; however, its effects on interspecies electron transfer remain unknown. This study configured the feed according to COD ratios of ethanol: sodium acetate: sodium propionate: sodium butyrate of 5:2:1.5:1.5 (ethanol-type anaerobic digestion) and 0:5:2.5:2.5 (control), and ...

The influence of electrostatic field on the direct interspecies electron transfer (DIET) pathways for methane production was investigated in a batch bioelectrochemical anaerobic digester (BEAD). The ultimate methane production and methane yield in the BEAD reactor saturated to 925 ± 29 mL/L and 309.9 ± 9.6 mL CH4/g COD, respectively, which were much ...

Increase of methanogenesis in methane-producing microbial electrolysis cells (MECs) is frequently believed as a result of cathodic reduction of CO2. Recent studies indicated that this electromethanogenesis only accounted for a little part of methane production during anaerobic sludge digestion.
