The in situ production of methane was monitored in several types of tropical benthic
communities. A bed of Thalassia testudinum located in Caesar Creek (Florida Keys) …

Most probable numbers (MPNs) of methanogens in various salt marsh and estuarine
sediments were determined with an anaerobic, habitat-simulating culture medium with 80 …

Microbial methanogenesis is a known source of methane in marine environment, but the
factors affecting the production of methane from different pathways remain largely …

Methane hydrate found in marine sediments is thought to contain gigaton quantities of
methane and is considered an important potential fuel source and climate-forcing agent …

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 …

Anaerobic lake sediment incubated in vitro was investigated for its ability to mimic natural in
situ sediment activities, using rate of methane production for the comparison. Two lakes with …

Methane metabolism was investigated with respect to depth in intertidal microbial mats of
the Great Sippewissett Salt Marsh, Massachusetts. Although sulfate‐reducing organisms …

Methane release rates from the sediment in the lake were estimated by a batch culture. The
methane release rates were decreased from 6.1±0.7 mgCH4-m− 2-h− 1 at top 5 cm depth to …

Microbial methanogenesis in the subsurface seafloor is responsible for the formation of
large and dynamic gas reservoirs like the recently discovered gas hydrate deposits. Gas …

Tropical lake sediments are a significant source for the greenhouse gas methane. We
studied function (pathway, rate) and structure (abundance, taxonomic composition) of the …
