Electroactive Microbiomes: Electron Transfer Mechanisms and Environmental Biotechnology Applications. [PDF]

Environ Microbiol Rep
Electroactive microbiomes couple direct, mediated, conductive, and interspecies electron transfer with biofilm organisation to drive wastewater treatment, bioremediation, resource recovery, carbon conversion, and biosensing. Their performance depends on balancing electron transfer, mass transport, community structure, and electrode–biofilm interactions

Methanobacterium Capable of Direct Interspecies Electron Transfer

, 2020
Direct interspecies electron transfer (DIET) from bacteria to methanogens is a revolutionary concept for syntrophic metabolism in methanogenic soils/sediments and anaerobic digestion. Previous studies have indicated that the potential for DIET is limited

Structural and Bioelectrochemical Elucidation of Direct Electron Transfer-type Membrane-bound Fructose Dehydrogenase [PDF]

, 2022
Flavin adenine dinucleotide (FAD)-dependent fructose dehydrogenase (FDH) from Gluconobacter japonicus NBRC3260, a membrane-bound flavohemoprotein capable of direct electron transfer (DET)-type bioelectrocatalysis, was investigated from the viewpoints of ...

Graphene Facilitates Biomethane Production from Protein-Derived Glycine in Anaerobic Digestion

iScience, 2018
Summary: Interspecies electron transfer is a fundamental factor determining the efficiency of anaerobic digestion (AD), which involves syntrophy between fermentative bacteria and methanogens.

Promoting direct interspecies electron transfer with activated carbon

, 2012
Granular activated carbon (GAC) is added to methanogenic digesters to enhance conversion of wastes to methane, but the mechanism(s) for GAC's stimulatory effect are poorly understood. GAC has high electrical conductivity and thus it was hypothesized that

Intermolecular Carbon–Carbon Naphthalene Coupling Involves a Radical Mechanism Driven by Cytochrome P450 in Alternaria alternata

Angewandte Chemie, EarlyView.
1,8‐DHN is an important intermediate to form complex aromatic ring systems. Phenol‐coupling reactions are important for the dimerization of two molecules. Here, we show that a fungal cytochrome P450 enzyme catalyzes specific C─C bonds. ABSTRACT Dihydroxynaphthalene (DHN) derivatives are precursors of biologically important molecules, including melanin ...

Towards engineering application: Integrating current strategies of promoting direct interspecies electron transfer to enhance anaerobic digestion

Chemical Engineering Journal Advances, 2022
The study present here was to integrate the current engineering strategies of promoting direct interspecies electron transfer (DIET), ethanol-type fermentation pretreatment, and conductive materials (zero-valent iron [ZVI] and graphite) supplemented, to ...

Interspecies Electron Transfer via Hydrogen and Formate Rather than Direct Electrical Connections in Cocultures of Pelobacter carbinolicus and Geobacter sulfurreducens

, 2012
Direct interspecies electron transfer (DIET) is an alternative to interspecies H-2/formate transfer as a mechanism for microbial species to cooperatively exchange electrons during syntrophic metabolism.

A new model for electron flow during anaerobic digestion: direct interspecies electron transfer to Methanosaeta for the reduction of carbon dioxide to methane

, 2013
Anaerobic conversion of organic wastes and biomass to methane is an important bioenergy strategy, which depends on poorly understood mechanisms of interspecies electron transfer to methanogenic microorganisms.

Gm26550 Modulates Learning and Memory by Increasing IGF1 mRNA Expression and Stability in Nrf2−/− Mice

Advanced Science, EarlyView.
The present study shows that Nrf2 directly binds to the Gm26550 promoter, thereby activating Gm26550 transcription and increasing its expression. Mechanistically, Gm26550 promotes IGF1 expression by functionally antagonizing miR‐26a‐5p‐mediated repression and sequestering the RBP KHSRP, thereby enhancing hippocampal neuronal synaptic plasticity and ...
