Hydrogen concentrations as an indicator of the predominant terminal electron-accepting reactions in aquatic sediments
Derek R. Lovley,Steve Goodwin +1 more
TLDR
In this article, the authors investigated factors controlling the concentration of dissolved hydrogen gas in anaerobic sedimentary environments and found that only microorganisms catalyze the oxidation of H 2 coupled to the reduction of nitrate, Mn(IV), Fe(III), sulfate, or carbon dioxide.About:

Dissimilatory Fe(III) and Mn(IV) reduction.
TL;DR: The physiological characteristics of Geobacter species appear to explain why they have consistently been found to be the predominant Fe(III)- and Mn(IV)-reducing microorganisms in a variety of sedimentary environments.

Electricity production by geobacter sulfurreducens attached to electrodes
Daniel R. Bond,Derek R. Lovley +1 more
TL;DR: The results suggest that the effectiveness of microbial fuel cells can be increased with organisms such as G. sulfurreducens that can attach to electrodes and remain viable for long periods of time while completely oxidizing organic substrates with quantitative transfer of electrons to an electrode.

Soil microorganisms as controllers of atmospheric trace gases (H2, CO, CH4, OCS, N2O, and NO).
TL;DR: It is completely unclear how important microbial diversity is for the control of trace gas flux at the ecosystem level, and different microbial communities may be part of the reason for differences in trace gas metabolism, e.g., effects of nitrogen fertilizers on CH4 uptake by soil; decrease of CH4 production with decreasing temperature.
Book ChapterDOI
Dissimilatory Fe(III) and Mn(IV) reduction.
TL;DR: The ability to oxidize hydrogen with the reduction of Fe(III) is a highly conserved characteristic of hyperthermophilic microorganisms, most notably those in the Geobacteraceae family as mentioned in this paper.

Biogeochemistry of landfill leachate plumes
Thomas Højlund Christensen,Peter Kjeldsen,Poul Løgstrup Bjerg,Dorthe Lærke Jensen,J. Christensen,Anders Baun,Hans-Jørgen Albrechtsen,Gorm Heron +7 more
TL;DR: The literature has been critically reviewed in order to assess the attenuation processes governing contaminants in leachate affected aquifers as discussed by the authors, focusing on dissolved organic matter, xenobiotic organic compounds, inorganic macrocomponents as anions and cations, and heavy metals.

Early oxidation of organic matter in pelagic sediments of the eastern equatorial Atlantic: suboxic diagenesis
Philip N. Froelich,Gary P. Klinkhammer,Michael L. Bender,Nile A. Luedtke,G.R. Heath,Doug Cullen,Paul Dauphin,Doug Hammond,Blayne Hartman,Val Maynard +9 more
TL;DR: Pore water profiles of total CO 2, pH, PO 3−4, NO − 3 plus NO − 2, SO 2− 4, S 2−, Fe 2+ and Mn 2+ have been obtained in cores from pelagic sediments of the eastern equatorial Atlantic under waters of moderate to high productivity as mentioned in this paper.

Early Diagenesis: A Theoretical Approach
TL;DR: In this article, Berner developed the mathematical theory of early diagenesis, introducing a general diagenetic equation and discussing it in terms of each major diagenetics process, including diffusion, compaction, pore-water flow, burial advection, bioturbation, adsorption, radioactive decay and especially chemical and biochemical reactions.

The Chemistry of Submerged Soils
TL;DR: In this paper, the chemistry of submerged soils is discussed and the role of lake, estuarine, and ocean sediments as reservoirs of nutrients for aquatic plants and as sinks for terrestrial wastes.
