Anaerobic microorganisms play key roles in the biogeochemical cycling of methane and non-
methane alkanes. To date, there appear to be at least three proposed mechanisms of …

Archaea are widespread in marine sediments, but their occurrence and relationship with
natural salinity gradients in estuarine sediments is not well understood. This study …

Temperature is one of the key constraints on the spatial extent, physiological and
phylogenetic diversity, and biogeochemical function of subsurface life. A model system to …

Alkanes comprise a substantial fraction of crude oil and are prevalent at marine seeps.
These environments are typically anoxic and host diverse microbial communities that grow …

A mesophilic deltaproteobacterium, designated strain SPRT, was isolated from a
methanogenic consortium capable of degrading long-chain paraffins. Cells were motile …

Based on the transient exposure of Chesapeake Bay sediments to hydrocarbons and the
metabolic versatility of known anaerobic alkane-degrading microorganisms, it was …
