Facilitation of interspecies electron transfer in anaerobic processes through pine needle biochar
Water Science and Technology, 2022 Role of biochar in promoting methanogenesis during anaerobic processes was investigated in this research. Biochar produced from Himalayan pine needles was used as medium for conductive material mediated interspecies electron transfer (CM-IET) amongst the

Microbial interspecies electron transfer via electric currents through conductive minerals. [PDF]
Proc Natl Acad Sci U S A, 2012 In anaerobic biota, reducing equivalents (electrons) are transferred between different species of microbes [interspecies electron transfer (IET)], establishing the basis of cooperative behaviors and community functions. IET mechanisms described so far are based on diffusion of redox chemical species and/or direct contact in cell aggregates.

Methanobacterium Capable of Direct Interspecies Electron Transfer [PDF]
Environmental Science & Technology, 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 to methanogens in the Methanosarcinales, leading to the assumption that an abundance of other types

Modeling of interspecies electron transfer in anaerobic microbial communities
Current Opinion in Biotechnology, 2021 Interspecies electron transfer (IET) is a key phenomenon in anaerobic ecosystems, which is traditionally modeled as hydrogen transfer. Recently discovered alternative mediated IET (MIET) or direct IET (DIET) offer exciting alternative mechanisms of microbial partnerships that could lead to new strategies for the improvement of biotechnologies. Here, we

Novel Outlook in Microbial Ecology: Nonmutualistic Interspecies Electron Transfer
Trends in Microbiology, 2020 Recent advances in microbial electrochemical technologies have revealed the existence of numerous and highly diverse microorganisms able to exchange electrons with electrodes. This diversity could reflect the capacity of microorganisms to release and/or retrieve electrons with each other in natural environments.

Electrochemical Enrichment and Isolation of Electrogenic Bacteria from 0.22 µm Filtrate
Microorganisms, 2022 Ultramicrobacteria (UMB) that can pass through a 0.22 µm filter are attractive because of their novelty and diversity. However, isolating UMB has been difficult because of their symbiotic or parasitic lifestyles in the environment.
