Community structure, cellular rRNA content, and activity of sulfate-reducing bacteria in marine Arctic sediments

Article Abstract:

Desulfosarcina and Desulfococcus make up about 70% of the marine sulfate-reducing community in the Artic, with Desulfosarcina variabilis making up about half of the community. Sulfate reduction was highest in the top few centimeters of soil.

Quantitative molecular analysis of the microbial community in marine arctic sediments (Svalbard)

Article Abstract:

The phylogenetic composition of Svalbard marine arctic sediment is presented, obtained from rRNA slot blot hybridization and fluorescence in situ hybridization techniques. A large microbial faction was found within the top 5 cm of the sample, with Cytophaga-Flavobacterium and delta-proteobacterial sulfate-reducing bacteria being the most abundant groups.

Phylogenetic affiliation and quantification of psychrophilic sulfate-reducing isolates in marine Arctic sediments

Article Abstract:

Research was conducted to examine the phylogenetic affiliation and quantification of psychrophilic sulfate-reducing isolates in marine Arctic sediments. It was shown that psychrohilic sulfate-reducing bacteria are related to mesophic strains and are likely to be phylogenetically diverse as the mesophiles. The abundance of the new group of psychrophilic sulfate-reducing isolates suggests that they may have an important role to play in the sulfur cycle of marine sediments.
