Manganese dioxide reduction kinetics by Geobacter sulfurreducens and associated biofilm morphology in a flow-through reactor
… reduction kinetics of manganese dioxide using Geobacter sulfurreducens, an extensively studied DMRB, with acetate as the electron donor. At low flow rates, a yield of 3.44x1010 ± 2.54x1010 cells/mmol MnO2 was calculated and a maximum specific growth rate of 0.02 1/hr was estimated. The half …

Spectroscopic Studies of Abiotic and Biological Nanomaterials: Silver Nanoparticles, Rhodamine 6G Adsorbed on Graphene, and c-Type Cytochromes and Type IV Pili in Geobacter sulfurreducens
… by the dissimilatory metal-reducing bacterium Geobacter sulfurreducens. Although these systems are quite different in some ways, they can all be considered examples of nanomaterials. A nanomaterial is generally defined as having at least one dimension below 100 nm in size. Silver nanoparticles, …

Crystallographic studies on diheme cytochrome <i>c</i> enzymes
… wie z.B. Sauerstoff, Nitrat oder Sulfat. Da Geobacter-Arten zu den vorherrschenden Mikroorganismen in vielen Bodenhabitaten gehören, wo die dissimilatorische Metallreduktion den dominierenden Stoffwechelprozess darstellt, ist der Elektronentransport innerhalb der Bakterien zu den unlöslichen …

Electrical-phenotyping of the bacterial envelope using microfluidics
… variant electrochemical activities, including Geobacter sulfurreducens, Shewanella oneidensis, and Escherichia coli heterologously expressing Shewanella EET pathways. We also applied 3DiDEP to achieve rapid quantification of LPS, the major component and virulence determinant in Gram-negative …

Integrating photosystem II and electroactive bacteria with three-dimensional electrodes for semi-artificial photosynthesis
… electrode to accommodate metal-reducing bacteria Geobacter sulfurreducens and Shewanella loihica. Their colonisation and current production in electrodes arising from anaerobic respiration are studied. Chapter 6 utilises the resulting biohybrid electrodes to drive reducing reactions within and …

Structural and biochemical characterization of diheme <i>c</i>-type cytochromes
… DHC2 aus dem anaeroben Mikroorganismus Geobacter sulfurreducens wurde in dem Bakterium Escherichia coli überexprimiert und mittels Affinitätschromatographie bzw. Gelfiltrationschromatographie bis zur Homogenität aufgereinigt. Das Protein wurde mittels UV/Vis-Spektralphotometrie, …

Application of Surface Enhanced Raman Spectroscopy to Biological Systems
… Untersuchung von Biofilmen des Bakteriums Geobacter Sulfurreducens demonstriert. Dies ist möglich, da das Bakterium eine Reihe von Multihämproteinen, sogenannten "outer membrane cytochromes" (Omcs), besitzt, die für den extrazellulären Elektronentransfer verantwortlich sind. Besonders stark …

Biofilm formation by Shewanella oneidensis MR-1 towards fundamental understanding of anode respiring communities
… extra-cellular electron transfer (EET). To date, Geobacter sulfurreducens has been identified as producing not only the largest current density but also large population density biofilms, of the known model organisms commonly used within the field. Another common model organism associated with …

Long-range extracellular electron transport by dissimilatory metal-reducing bacteria across a physical separation
… of birnessite by microbial nanowires using Geobacter sulfurreducens KN400. The nanoporous wall in these experiments was composed of an array of pillars separated by <200 gaps (i.e. nanopores) to provide nanowires access to the entire depth of deposited birnessite. Using optical microscopy …
