Enhanced direct interspecies electron transfer with transition metal oxide accelerants in anaerobic digestion

Bioresource Technology, 2021
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, 2021
Hydrogen 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 Between Archaea and Bacteria

2017
Archaea 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.

Ethanol-type anaerobic digestion enhanced methanogenic performance by stimulating direct interspecies electron transfer and interspecies hydrogen transfer

Bioresource Technology
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 ...

Quorum Sensing Enhances Direct Interspecies Electron Transfer in Anaerobic Methane Production

Environmental Science & Technology
Direct interspecies electron transfer (DIET) provides an innovative way to achieve efficient methanogenesis, and this study proposes a new approach to upregulate the DIET pathway by enhancing quorum sensing (QS). Based on long-term reactor performance, QS enhancement achieved more vigorous methanogenesis with 98.7% COD removal efficiency.

Direct interspecies electron transfer accelerates syntrophic oxidation of butyrate in paddy soil enrichments

Environmental Microbiology, 2014
Summary Syntrophic interaction occurs during anaerobic fermentation of organic substances forming methane as the final product. H 2 and formate are known to serve as the electron carriers in this process.

Electrochemical evidence for direct interspecies electron transfer between Geobacter sulfurreducens and Prosthecochloris aestuarii

Bioelectrochemistry, 2019
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-

Comparing the effects of magnetite-mediated direct interspecies electron transfer with biogas mixing-driven interspecies hydrogen transfer on anaerobic digestion

Chemosphere
Although the promotive effect of direct interspecies electron transfer (DIET) on methane production has been well-documented, the practical applicability of DIET in different scenarios have not yet been systematically studied. This study compared the effects of magnetite-mediated DIET with conventional biogas mixing-driven interspecies hydrogen ...

The survival strategy of direct interspecies electron transfer-capable coculture under electron donor-limited environments

Science of The Total Environment
Direct interspecies electron transfer (DIET) has been considered as an effective mechanism for interspecies electron exchange in microbial syntrophy. Understanding DIET-capable syntrophic associations under energy-limited environments is important because these conditions more closely approximate those found in natural subsurface environments than in ...
