Production of gold nanoparticles by electrode-respiring Geobacter sulfurreducens biofilms [PDF]

Enzyme and Microbial Technology, 2016
The goal of this work was to synthesize gold nanoparticles (AuNPs) using electrode-respiring Geobacter sulfurreducens biofilms. We found that AuNPs are generated in the extracellular matrix of Geobacter biofilms and have an average particle size of 20nm. The formation of AuNPs was verified using TEM, FTIR and EDX.

The genome sequence of Geobacter metallireducens: features of metabolism, physiology and regulation common and dissimilar to Geobacter sulfurreducens

BMC Microbiology, 2009
Background The genome sequence of Geobacter metallireducens is the second to be completed from the metal-respiring genus Geobacter, and is compared in this report to that of Geobacter sulfurreducens in order to understand their metabolic, physiological ...

Characterization and modelling of interspecies electron transfer mechanisms and microbial community dynamics of a syntrophic association [PDF]

, 2013
Syntrophic associations are central to microbial communities and thus have a fundamental role in the global carbon cycle. Despite biochemical approaches describing the physiological activity of these communities, there has been a lack of a mechanistic ...

Advancements in flexible memristors for neuromorphic computing: Materials, mechanisms, and applications in synaptic emulation

FlexMat, Volume 2, Issue 3, Page 390-419, October 2025.
Memristors, as the fourth fundamental passive circuit element, are promising devices that can mimic synaptic functions in neural networks due to their nonlinear memory characteristics. This paper reviews recent advancements in material selection, resistive switching mechanisms, and flexible memristor architectures for artificial neural networks ...

Anode potential influences the structure and function of anodic electrode and electrolyte-associated microbiomes [PDF]

, 2016
Three bioelectrochemical systems were operated with set anode potentials of +300 mV, +550 mV and +800 mV vs. Standard Hydrogen Electrode (SHE) to test the hypothesis that anode potential influences microbial diversity and is positively associated with ...

Current Practices for Analyzing Soils and Sediments via Mössbauer Spectroscopy

Journal of Plant Nutrition and Soil Science, Volume 188, Issue 5, Page 742-773, October 2025.
ABSTRACT Environmental scientists are increasingly returning to Mössbauer spectroscopy (MBS) to reveal details about iron (Fe)‐bearing phases in soils and sediments. MBS is particularly powerful at distinguishing between Fe(II) and Fe(III) and, given appropriate background information, can offer exceptionally precise information on Fe speciation in ...

Microbial Communities of the Providence River [PDF]

, 2015
The Providence River has been industrialized for over one-hundred years. Industries such as oil storage and metal recycling facilities have left high levels of pollutant metals, including lead (Pb), in the soil and water.

Current understanding of electroautotrophy and its relevance in astrobiology‐related research

mLife, Volume 4, Issue 5, Page 473-493, October 2025.
Abstract Electroautotrophy—the use of extracellular electrons as the primary energy source for autotrophic metabolism—remains understudied compared to photoautotrophy and chemoautotrophy. Its occurrence in deep‐earth and deep‐sea environments suggests profound implications for astrobiology, yet electroautotrophic microorganisms remain poorly explored ...

Forming electrochemically active biofilms from garden compost under chronoamperometry [PDF]

, 2008
Dimensionally stable anodes (DSA) were polarized at different constant potential values for several days in garden compost. After an initial lag period ranging from 1 to 10.5 days, the current increased fast and then stabilized for days.
