1. The concentration of sulphate is low in lakes and sulphur cycling has often been
neglected in studies of organic matter diagenesis in lake sediments. The cycling of sulphur …

Freshwater wetlands are a major source of the greenhouse gas methane but at the same
time can function as carbon sink. Their response to global warming and environmental …

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

A new chemolithotrophic bacterial metabolism was discovered in anaerobic marine
enrichment cultures. Cultures in defined medium with elemental sulfur (S0) and amorphous …

Pyrite (FeS2) and iron monosulfide (FeS) play a central role in the sulfur and iron cycles of
marine sediments. They may be buried in the sediment or oxidized by O2 after transport by …

In bacterial cultures we measured sulfur isotope fractionation during transformations of
thiosulfate (S2O32−) and sulfite (SO32−), pathways which may be of considerable …

We studied the inhibitory mechanism of nitrate and its denitrification products (nitrite, NO,
N2O) on the production of CH4 and the concentrations of reductants (H2, acetate …

The sulfate–methane transition (SMT) zone is a diagenetic transition within anoxic marine
sediments created by the metabolic activity of a consortium of sulfate-reducing bacteria and …

A combination of polymerase chain reaction-assisted rRNA sequence retrieval and
fluorescent oligonucleotide probing was used to identify in situ a hitherto unculturable, big …

Most of the sulfide produced in surface marine sediments is eventually oxidized back to
sulfate via sulfur compounds of intermediate oxidation state in a complex web of competing …
