Sediment pore water samples obtained from a 19 m station in Green Bay in Lake Michigan
were examined for levels of ambient dissolved methane and copper, and for the potential for …

Methane is an important product formed during the bacterial degradation of organic matter in
environments such as flooded soils, wetlands, estuaries, marine and freshwater sediments …

Rates of methane production via both acetate fermentation and CO 2 reduction were directly
measured with radiotracer techniques in the sulfate-depleted sediments of Saanich and …

A survey of reported methane distributions in sediments and the adjacent overlying water
shows distinct differences between freshwater and marine environments. These differences …

ABSTRACT Choline (N, N, N-trimethylethanolamine), which is widely distributed in
membrane lipids and is a component of sediment biota, has been shown to be utilized …

Abstract At the Campeche Knolls in the southern Gulf of Mexico large-scale hydrocarbon
emissions are associated with numerous salt tectonic structures. A notable feature of this …

14C-labelled methane, biologically prepared by Methanobacterium thermoautotrophicum, is
widely used to determine methane oxidation rates. However, M. thermoautotrophicum …

Salinity is an important environmental control of aerobic methane oxidation, which reduces
the emission of the potent greenhouse gas methane into the atmosphere. The effect of …

Methanogenic degradation of organic matter occurs in a wide temperature range from
psychrophilic to extreme thermophilic conditions. Mesophilic and thermophilic …

Although abundant geochemical data indicate that anaerobic methane oxidation occurs in
marine sediments, the linkage to specific microorganisms remains unclear. In order to …
