Microbial Communities from Methane Hydrate-Bearing Deep Marine Sediments in a Forearc Basin
ABSTRACT Microbial communities in cores obtained from methane hydrate-bearing deep marine sediments (down to more than 300 m below the seafloor) in the forearc basin of the Nankai Trough near JapanExpand

Phylogenetic and Physiological Diversity of Microorganisms Isolated from a Deep Greenland Glacier Ice Core
ABSTRACT We studied a sample from the GISP 2 (Greenland Ice Sheet Project) ice core to determine the diversity and survival of microorganisms trapped in the ice at least 120,000 years ago.Expand

Phylogenetic Analysis of Anaerobic Psychrophilic Enrichment Cultures Obtained from a Greenland Glacier Ice Core
ABSTRACT The examination of microorganisms in glacial ice cores allows the phylogenetic relationships of organisms frozen for thousands of years to be compared with those of current isolates. WeExpand

Estimated Minimal Divergence Times of the Major Bacterial and Archaeal Phyla
Previous calibrations of prokaryotic phylogenetic events were based on the vertebrate fossil record because a detailed microbial fossil record does not exist. Recently, compounds (2-methylhopanoids)Expand

Biochemical characterization of a beta-galactosidase with a low temperature optimum obtained from an Antarctic arthrobacter isolate.
A psychrophilic gram-positive isolate was obtained from Antarctic Dry Valley soil. It utilized lactose, had a rod-coccus cycle, and contained lysine as the diamino acid in its cell wall. ConsistentExpand

Rhodoglobus vestalii gen. nov., sp. nov., a novel psychrophilic organism isolated from an Antarctic Dry Valley lake.
A novel, psychrophilic, gram-positive bacterium (designated strain LV3T) from a lake near the McMurdo Ice Shelf, Antarctica, has been isolated and characterized. This organism formed red-pigmentedExpand

Characterization of a Salt-Tolerant Family 42 β-Galactosidase from a Psychrophilic AntarcticPlanococcus Isolate
ABSTRACT We isolated a gram-positive, halotolerant psychrophile from a hypersaline pond located on the McMurdo Ice Shelf in Antarctica. A phylogenetic analysis of the 16S rRNA gene sequence of thisExpand

Biochemical and phylogenetic analyses of psychrophilic isolates belonging to the Arthrobacter subgroup and description of Arthrobacter psychrolactophilus, sp. nov.
Abstract During our work on psychrophilic microorganisms we obtained a large collection of new isolates. In order to identify six of these, we examined their growth properties, cell wallExpand

Phylogenetic analysis of Shiga toxin 1 and Shiga toxin 2 genes associated with disease outbreaks
BackgroundShiga toxins 1 and 2 (Stx1 and Stx2) are bacteriophage-encoded proteins that have been associated with hemorrhagic colitis, hemolytic uremic syndrome and other severe disease conditions.Expand

Design and Validation of ureC-based Primers for Groundwater Detection of Urea-Hydrolyzing Bacteria
Polymerase chain reaction primers based on the ureC gene are described for use in detecting diverse groundwater urea-hydrolyzing bacteria. Six degenerate primers were designed and evaluated for theirExpand
