Background Lagoons are common along coastlines worldwide and are important for
biogeochemical element cycling, coastal biodiversity, coastal erosion protection and blue …

Anoxygenic phototrophic sulfide oxidation by green and purple sulfur bacteria (PSB) plays a
key role in sulfide removal from anoxic shallow sediments and stratified waters. Although …

Microbial sulfide oxidation in aquatic environments is an important ecosystem process, as
sulfide is potently toxic to aerobic organisms. Sulfide oxidation in anoxic waters can prevent …

Green sulfur bacteria are obligate photolithoautotrophs that require highly reducing
conditions for growth and can utilize only a very limited number of carbon substrates. These …

A major goal of microbial ecology is the identification and characterization of those
microorganisms which govern transformations in natural ecosystems. This review …

Meromictic lakes are interesting ecosystems to study anaerobic microorganisms due their
permanent stratification allowing the formation of a stable anoxic environment. The …

Previously, we presented data that indicated microbial sulfide oxidation would out-compete
strictly chemical, abiotic sulfide oxidation reactions under nearly all conditions relevant to …

Microbial metabolism is the engine that drives global biogeochemical cycles, yet many key
transformations are carried out by microbial consortia over short spatiotemporal scales that …

Background The planetary sulfur cycle is a complex web of chemical reactions that can be
microbial-mediated or can occur spontaneously in the environment, depending on the …

Background The sulfur cycle encompasses a series of complex aerobic and anaerobic
transformations of S-containing molecules and plays a fundamental role in cellular and …
