Geobacter species specialize in making electrical contacts with extracellular electron
acceptors and other organisms. This permits Geobacter species to fill important niches in a …

This paper reviews the factors affecting trace metal behaviour in estuarine and riverine
floodplain soils and sediments. Spatial occurrence of processes affecting metal mobility and …

Manganese is one of the most abundant elements on Earth. The oxidation of manganese
has long been theorized—yet has not been demonstrated,–—to fuel the growth of …

For the past 3.8 billion years, the geochemistry of the Earth's surface-its atmosphere, waters
and exposed crust-has been determined by the presence of biota. Photosynthetic organisms …

The oxidation of organic matter coupled to the reduction of Fe (III) or Mn (IV) is one of the
most important biogeochemical reactions in aquatic sediments, soils, and groundwater. This …

Uncovers the Key Role Microbes Play in the Transformation of Oxidizable and Reducible
MineralsMany areas of geomicrobial processes are receiving serious attention from …

ABSTRACT Dissimilatory Fe (III) and Mn (IV) reduction has an important influence on the
geochemistry of modern environments, and Fe (III)-reducing microorganisms, most notably …

The gram-negative metal-reducing microorganism, previously known as strain GS-15, was
further characterized. This strict anaerobe oxidizes several short-chain fatty acids, alcohols …

Microorganisms can enzymatically reduce a variety of metals in metabolic processes that
are not related to metal assimilation. Some microorganisms can conserve energy to support …

We used a combination of porewater and solid phase analysis, as well as a series of
sediment incubations, to quantify organic carbon oxidation by dissimilatory Fe reduction, Mn …
