Microbial Diversity of Hydrothermal Sediments in the Guaymas Basin: Evidence for Anaerobic Methanotrophic Communities
ABSTRACT Microbial communities in hydrothermally active sediments of the Guaymas Basin (Gulf of California, Mexico) were studied by using 16S rRNA sequencing and carbon isotopic analysis of archaealExpand

Phylogenetic relationships ofThiomicrospira species and their identification in deep-sea hydrothermal vent samples by denaturing gradient gel electrophoresis of 16S rDNA fragments
Denaturing gradient gel electrophoresis (DGGE) of PCR-amplified 16S rDNA fragments was used to explore the genetic diversity of hydrothermal vent microbial communities, specifically to determine theExpand

Population Structure and Phylogenetic Characterization of Marine Benthic Archaea in Deep-Sea Sediments
ABSTRACT During the past few years Archaea have been recognized as a widespread and significant component of marine picoplankton assemblages and, more recently, the presence of novel archaealExpand

Influence of mesoscale eddies on new production in the Sargasso Sea
It is problematic that geochemical estimates of new production — that fraction of total primary production in surface waters fuelled by externally supplied nutrients — in oligotrophic waters of theExpand

Stable isotope studies of the carbon, nitrogen and sulfur cycles in the Black Sea and the Cariaco Trench
Abstract Samples for stable isotope studies of possible chemosynthesis in anoxic basins were collected in 1986 in the Cariaco Trench and May 1988 in the Black Sea. POM (particulate organic matter)Expand

Geomicrobiology of Deep-Sea Hydrothermal Vents
During the cycling of seawater through the earth's crust along the mid-ocean ridge system, geothermal energy is transferred into chemical energy in the form of reduced inorganic compounds. TheseExpand

Pyrolobus fumarii, gen. and sp. nov., represents a novel group of archaea, extending the upper temperature limit for life to 113°C
Abstract A novel, irregular, coccoid-shaped archaeum was isolated from a hydrothermally heated black smoker wall at the TAG site at the Mid Atlantic Ridge (depth 3650 meters). It grew at between 90°CExpand
