Enhanced benthic nitrous oxide and ammonium production after natural oxygenation of long‐term anoxic sediments

open access: yesLimnology and Oceanography, Volume 67, Issue 2, Page 419-433, February 2022., 2022
Abstract Coastal and shelf sediments are central in the global nitrogen (N) cycle as important sites for the removal of fixed N. However, this ecosystem service can be hampered by ongoing deoxygenation in many coastal areas. Natural reoxygenation could reinstate anoxic sediments as sites where fixed N is removed efficiently. To investigate this further,

Detrimental impact of the <i>Geobacter metallireducens</i> type VI secretion system on direct interspecies electron transfer. [PDF]

open access: yesMicrobiol Spectr, 2023
Direct interspecies electron transfer (DIET) is important in anaerobic communities of environmental and practical significance. Other than the need for close physical contact for electrical connections, the interactions of DIET partners are poorly ...

Interaction of living cable bacteria with carbon electrodes in bioelectrochemical systems. [PDF]

open access: yesAppl Environ Microbiol
Cable bacteria are filamentous bacteria that couple the oxidation of sulfide in sediments to the reduction of oxygen via long-distance electron transport over centimeter distances through periplasmic wires.

Generation of High Current Densities in Geobacter sulfurreducens Lacking the Putative Gene for the PilB Pilus Assembly Motor

open access: yesMicrobiology Spectrum, 2021
Geobacter sulfurreducens is commonly employed as a model for the study of extracellular electron transport mechanisms in the Geobacter species. Deletion of pilB, which is known to encode the pilus assembly motor protein for type IV pili in other bacteria,

Innovative biological approaches for monitoring and improving water quality

open access: yesFrontiers in Microbiology, 2015
Water quality is largely influenced by the abundance and diversity of indigenous microbes present within an aquatic environment. Physical, chemical and biological contaminants from anthropogenic activities can accumulate in aquatic systems causing ...

The Archaellum of Methanospirillum hungatei Is Electrically Conductive

open access: yesmBio, 2019
Microbially produced electrically conductive protein filaments are of interest because they can function as conduits for long-range biological electron transfer. They also show promise as sustainably produced electronic materials.

Isolation and Characterization of Human Gut Bacteria Capable of Extracellular Electron Transport by Electrochemical Techniques

open access: yesFrontiers in Microbiology, 2019
Microorganisms are known to exhibit extracellular electron transfer (EET) in a wide variety of habitats. However, as for the human microbiome which significantly impacts our health, the role and importance of EET has not been widely investigated. In this

e-Biologics: Fabrication of Sustainable Electronics with “Green” Biological Materials

open access: yesmBio, 2017
The growing ubiquity of electronic devices is increasingly consuming substantial energy and rare resources for materials fabrication, as well as creating expansive volumes of toxic waste. This is not sustainable.
