Nano Fe3O4-modified graphene enhancing the removal of sulfamethoxazole under anaerobic digestion and sulfate reduction conditions through improved direct interspecies electron transfer.

Bioresource Technology
Sulfamethoxazole (SMX) present in pharmaceutical wastewater may pose significant risks to ecological health. This study evaluated the role of redox mediator nano Fe3O4-modified graphene (GF) to mediate SMX biotransformation in a sulfate reduction reactor

Dual roles of zero-valent iron in dry anaerobic digestion: Enhancing interspecies hydrogen transfer and direct interspecies electron transfer

Waste Management, 2020
Although commonly viewed as a promising method, dry anaerobic digestion is not been widely applied to dispose of food wastes, especially in developing countries because of its insufficiency in handling with lower mass transfer and high acidic accumulation of the system.

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.

Biochar@MIL-88A(Fe) Accelerates Direct Interspecies Electron Transfer and Hydrogen Transfer in Waste Activated Sludge Anaerobic Digestion: Exploring Electron Transfer and Biomolecular Mechanisms.

Environmental Research
Adding additives exogenously is an effective strategy to enhance methanogenic activity and improve AD stability. Corn straw-based biochar@MIL-88A(Fe) (BM) was synthesized herewith and used as an exogenous additive to boost methane (CH4) production. After
