In vitro demonstration of anaerobic oxidation of methane coupled to sulphate reduction in sediment from a marine gas hydrate area.
Anaerobic oxidation of methane (AOM) and sulphate reduction were examined in sediment samples from a marine gas hydrate area (Hydrate Ridge, NE Pacific) and did not provide evidence for one of these compounds acting as a free extracellular intermediate (intercellular shuttle) during AOM by the presently investigated consortia.

A conspicuous nickel protein in microbial mats that oxidize methane anaerobically
The abundance of the nickel protein (7% of extracted proteins) in the mat suggests an important role in AOM, and similarities to methyl-coenzyme M reductase from methanogenic archaea are revealed. Expand
Environmental control on anaerobic oxidation of methane in the gassy sediments of Eckernförde Bay (German Baltic)
We investigated the effect of seasonal environmental changes on the rate and distribution of anaerobic oxidation of methane (AOM) in Eckernforde Bay sediments (German Baltic Sea) and identifiedExpand
Environmental regulation of the anaerobic oxidation of methane: a comparison of ANME-I and ANME-II communities.
The ecological niches of methanotrophic Archaea seem to be mainly defined by the availability of methane and sulfate, but it remains open which additional factors lead to the dominance of ANME-I or -II in the environment. Expand
Biosynthesis of hopanoids by sulfate-reducing bacteria (genus Desulfovibrio).
It is demonstrated for the first time the capability of sulfate-reducing bacteria (SRB) to biosynthesize hopanoids, compounds that are quantitatively important and widely distributed biomarkers in recent and fossil sediments dating back to the late Archean. Expand
Soil microbial community changes as a result of long-term exposure to a natural CO2 vent
Abstract The capture and geological storage of CO2 can be used to reduce anthropogenic greenhouse gas emissions. To assess the environmental impact of potential CO2 leakage from deep storageExpand
The impact of a naturally occurring CO2 gas vent on the shallow ecosystem and soil chemistry of a Mediterranean pasture (Latera, Italy)
Recent research into CO2 geological storage has shown that it has potential to be a safe and effective way to rapidly decrease short-term anthropogenic CO2 emissions. Despite this progress,Expand
Cooccurrence of Aerobic and Anaerobic Methane Oxidation in the Water Column of Lake Plußsee
ABSTRACT Dissolved methane was investigated in the water column of eutrophic Lake Plußsee and compared to temperature, oxygen, and sulfide profiles. Methane concentrations and δ-13C signaturesExpand
Effects of N-fertilisation on CH4 oxidation and production, and consequences for CH4 emissions from microcosms and rice fields
The world's growing human population causes an increasing demand for food, of which rice is one of the most important sources. In rice production nitrogen is often a limiting factor. As a consequenceExpand
