Ferrihydrite is a widespread poorly crystalline Fe oxide which becomes easily coated by natural organic matter in the environment. This mineral-bound organic matter entirely changes the mineral surface properties and therefore the reactivity of the o

Geobacter bremensis sp. nov. and Geobacter pelophilus sp. nov., two dissimilatory ferric-iron-reducing bacteria

Autor: Kristina Lotte Straub, Berit E. E. Buchholz-Cleven

Publikováno v: International Journal of Systematic and Evolutionary Microbiology. 51:1805-1808

Two strictly anaerobic, dissimilatory ferric-iron-reducing bacteria, strains Dfr1T and Dfr2T, were isolated from freshwater mud samples with ferrihydrite as electron acceptor. Both strains also grew by reducing Mn(IV), S0 and fumarate. Electron donor

International audience; Electrochemically active (EA) biofilms were formed on metallic dimensionally stable anode-type electrode (DSA), embedded in garden compost and polarized at +0.50 V/SCE. Analysis of 16S rRNA gene libraries revealed that biofilm

Geobacter uraniireducens sp. nov., isolated from subsurface sediment undergoing uranium bioremediation

Autor: Helen A. Vrionis, Robert H. Findlay, Evgenya S. Shelobolina, Derek R. Lovley

Publikováno v: International journal of systematic and evolutionary microbiology. 58(Pt 5)

A Gram-negative, rod-shaped, motile bacterium, strain Rf4T, which conserves energy from dissimilatory Fe(III) reduction concomitant with acetate oxidation, was isolated from subsurface sediment undergoing uranium bioremediation. The 16S rRNA gene seq

Biofilms éléctroactifs : formation, caractérisation et mécanismes

Autor: Parot, Sandrine

Certaines bactéries, capables d'échanger des électrons avec un matériau conducteur sans l'aide de médiateur, forment sur la surface conductrice des biofilms électroactifs. Cette propriété bactérienne a été récemment découverte (2001). Le

Ferrihydrite reduction by Geobacter species is stimulated by secondary bacteria

Autor: Bernhard Schink, Kristina Lotte Straub

Publikováno v: Archives of microbiology. 182(2-3)

Geobacter species such as G. bremensis, G. pelophilus, and G. sulfurreducens are obligately anaerobic and grow in anoxic, non-reduced medium by fast reduction of soluble ferric citrate. In contrast, insoluble ferrihydrite was either only slowly or no

Diversity of Ferrous Iron-Oxidizing, Nitrate-Reducing Bacteria and their Involvement in Oxygen-Independent Iron Cycling

Autor: Kristina Lotte Straub, Bernhard Schink, Wilhelm Schönhuber, Berit E. E. Buchholz-Cleven

Publikováno v: Geomicrobiology Journal

In previous studies, three different strains (BrG1, BrG2, and BrG3) of ferrous iron-oxidizing, nitrate-reducing bacteria were obtained from freshwater sediments. All three strains were facultative anaerobes and utilized a variety of organic substrate
