Phylogenetic diversity of Archaea in sediment samples from a coastal salt marsh
Article Abstract:
A research was conducted to study the Archaea in salt marsh sediment samples from a tidal creek and from a vegetative marshland which showed active methanogenesis and sulfate reduction. 16S rRNA gene libraries created with Archaea-specific primers were utilized in the study. Related sequence clusters were common among sampled clones and generally contained representatives from the marsh top and sediment samples. Moreover, different sequences related to halophilic Archaea were observed in gene libraries.

Anaerobic versus aerobic degradation of dimethyl sulfide and methanethiol in anoxic freshwater sediments
Article Abstract:
Research was conducted to examine the anaerobic versus aerobic degradation of dimethyl sulfide and methanethiol in anoxic freshwater sediments. Inhibition experiments were performed with sodium tungstate and bromoethanesulfonic acid which revealed that the degradation of dimethyl sulfide and methanethiol in the incubations originated from methanogenic activity. Therefore, methanogenesis is the key mechanism of methanethiol and dimethyl sulfide consumption in freshwater sediments.
