Lack of production of electron-shuttling compounds or solubilization of Fe(III) during reduction of insoluble Fe(III) oxide by Geobacter metallireducens.

Lack of Production of Electron-Shuttling Compounds or Solubilization of Fe(III) During Reduction of Insoluble Fe(III) Oxide of Geobacter Metallireducens

A genetic system for Geobacter metallireducens: role of the flagellin and pilin in the reduction of Fe(III) oxide.

Geobacter metallireducens is an important model organism for many novel aspects of extracellular electron exchange and the anaerobic degradation of aromatic compounds, but studies of its physiology have been limited by a lack of techniques for gene deletion and replacement. Therefore, a genetic system was developed for G. metallireducens by making a number of modifications in the previously des...

Mechanisms for accessing insoluble Fe(III) oxide during dissimilatory Fe(III) reduction by Geothrix fermentans.

Mechanisms for Fe(III) oxide reduction were investigated in Geothrix fermentans, a dissimilatory Fe(III)-reducing microorganism found within the Fe(III) reduction zone of subsurface environments. Culture filtrates of G. fermentans stimulated the reduction of poorly crystalline Fe(III) oxide by washed cell suspensions, suggesting that G. fermentans released one or more extracellular compounds th...

Outer cell surface components essential for Fe(III) oxide reduction by Geobacter metallireducens.

Geobacter species are important Fe(III) reducers in a diversity of soils and sediments. Mechanisms for Fe(III) oxide reduction have been studied in detail in Geobacter sulfurreducens, but a number of the most thoroughly studied outer surface components of G. sulfurreducens, particularly c-type cytochromes, are not well conserved among Geobacter species. In order to identify cellular components ...

Title: Outer Cell Surface Components Essential for Fe(III) Oxide Reduction by Geobacter

24 Geobacter species are important Fe(III) reducers in a diversity of soils and sediments. 25 Mechanisms for Fe(III) oxide reduction have been studied in detail in Geobacter sulfurreducens, 26 but a number of the most thoroughly studied outer surface components of G. sulfurreducens, 27 particularly c-type cytochromes, are not well conserved among Geobacter species. In order to 28 identify cellu...
