Allying with armored snails: the complete genome of gammaproteobacterial endosymbiont
This study is the first complete genome analysis of gastropod endosymbiont and offers an opportunity to study genome evolution in a recently evolved endosYmbionts. Expand
Kosmotoga arenicorallina sp. nov. a thermophilic and obligately anaerobic heterotroph isolated from a shallow hydrothermal system occurring within a coral reef, southern part of the Yaeyama
A novel thermophilic and sulfur-reducing bacterium, strain S304T, was isolated from the Taketomi submarine hot spring shallow hydrothermal field located at southern part of the Yaeyama Archipelago, Japan and a new species in the genus Kosmotoga is proposed. Expand
A thermostable histamine oxidase from Arthrobacter crystallopoietes KAIT-B-007.
A thermostable histamine oxidase (EC 1.3.-) was found in cells of Arthrobacter crystallopoietes KAIT-B-007 isolated from soil and it is suggested that Cu2+ is essential for expression of histamines oxidase activity. Expand
Methylothermus subterraneus sp. nov., a moderately thermophilic methanotroph isolated from a terrestrial subsurface hot aquifer.
On the basis of distinct phylogenetic, chemotaxonomic and physiological characteristics, strain HTM55(T) represents a novel species of the genus M methylothermus, for which the name Methylothermus subterraneus sp. Expand
Isolation and Characterization of a Thermophilic, Obligately Anaerobic and Heterotrophic Marine Chloroflexi Bacterium from a Chloroflexi-dominated Microbial Community Associated with a Japanese
A novel marine thermophilic and heterotrophic Anaerolineae bacterium in the phylum Chloroflexi, strain SW7T, was isolated from an in situ colonization system deployed in the main hydrothermal vent ofExpand
Distribution and Niche Separation of Planktonic Microbial Communities in the Water Columns from the Surface to the Hadal Waters of the Japan Trench under the Eutrophic Ocean
The effects of suspended organic matter, as induced by seafloor deformation, on microbial communities in deep waters are highlighted and the occurrence of the distinctive hadal biosphere in global trench environments hypothesized in the previous study is confirmed. Expand
Physiological and Genomic Features of a Novel Sulfur-Oxidizing Gammaproteobacterium Belonging to a Previously Uncultivated Symbiotic Lineage Isolated from a Hydrothermal Vent
Chemolithoheterotrophy and the presence of homologous genes for virulence- and quorum sensing-related functions suggest that the sulfur-oxidizing chomolithotrophic microbes seek animal bodies and microbial biofilm formation to obtain supplemental organic carbons in hydrothermal ecosystems. Expand
Biogeography of Persephonella in deep-sea hydrothermal vents of the Western Pacific
This study is the first MLSA combined with phenotypic analysis indicative of allopatric speciation of deep-sea hydrothermal vent bacteria and reveals the clustering of isolates according to the geographic origin. Expand
Concentrations and distributions of amino acids in black and white smoker fluids at temperatures over 200 C
The distribution of amino acids in seafloor hydrothermal systems was investigated through the determination of the concentrations of total hydrolysable amino acids (THAAs), dissolved free amino acidsExpand
Structural analysis of the sheath of a sheathed bacterium, Leptothrix cholodnii.
NMR analysis of the hydrazinolysate revealed that the polysaccharide moiety of the sheath was constructed from a pentasaccharide repeating unit containing 2-amino-2-deoxygalacturonic acid (GalNA), as shown below. Expand
