Microbial dissimilatory sulfate reduction to sulfide is a predominant terminal pathway of
organic matter mineralization in the anoxic seabed. Chemical or microbial oxidation of the …

Signaling by H2S is proposed to occur via persulfidation, a posttranslational modification of
cysteine residues (RSH) to persulfides (RSSH). Persulfidation provides a framework for …

Replacement of fossil fuels with clean hydrogen has been recognized as the most feasible
approach of implementing CO 2-free hydrogen economy globally. However, large-scale …

Sedimentary pyrite formed in the water column, or during diagenesis in organic muds,
provides an accessible proxy for seawater chemistry in the marine rock record. Except for …

Building on the success of its 1993 predecessor, this second edition of Geochemistry,
Groundwater and Pollution has been thoroughly re-written, updated and extended to …

The globally important nature of wetland ecosystems has led to their increased protection
and restoration as well as their use in engineered systems. Underpinning the beneficial …

The sulfur biogeochemical cycle integrates the metabolic activity of multiple microbial
pathways (eg, sulfate reduction, disproportionation, and sulfide oxidation) along with abiotic …

The iron sulfides constitute a diverse group of solids and dissolved complexes many of
which play key roles in marine systems. The group is particularly complex in the lower …

Interactions of trace metals with sulfide in anoxic environments are important in determining
their chemical form and potential toxicity to organisms. In recent years, a considerable body …

Acid sulfate soils (ASS) contain substantial quantities of iron sulfide minerals or the oxidation
reaction products of these sulfidic minerals. Transformation of iron (Fe) and sulfur (S) …
