Cell proliferation at 122°C and isotopically heavy CH4 production by a hyperthermophilic methanogen under high-pressure cultivation
Under conventional growth conditions, the isotope fractionation of methanogenesis by M. kandleri strain 116 was similar to values previously reported for other hydrogenotrophic methanogens, but under high hydrostatic pressures, the atom fractionation effect became much smaller, and the kinetic isotope effect was one of the smallest effects ever reported.

Sulfurimonas paralvinellae sp. nov., a novel mesophilic, hydrogen- and sulfur-oxidizing chemolithoautotroph within the Epsilonproteobacteria isolated from a deep-sea hydrothermal vent polychaete
Strain GO25(T) represents the first deep-sea epsilonproteobacterium capable of growth by both hydrogen and sulfur oxidation and is proposed as the reclassification of Thiomicrospira denitrificans as Sulfurimonas denitRificans comb. Expand
Enzymatic properties and nucleotide and amino acid sequences of a thermostable β-agarase from a novel species of deep-sea Microbulbifer
The pattern of agarose hydrolysis showed that the enzyme was an endo-type β-agarase, and the final main product was neoagarotetraose, not inhibited by NaCl, EDTA, and various surfactants at high concentrations. Expand
Purification and Characterization of a Novel α-Agarase from a Thalassomonas sp.
An agar-degrading Thalassomonas bacterium, strain JAMB-A33, was isolated from the sediment off Noma Point, Japan, at a depth of 230 m. A novel α-agarase from the isolate was purified to homogeneityExpand
Neptunomonas japonica sp. nov., an Osedax japonicus symbiont-like bacterium isolated from sediment adjacent to sperm whale carcasses off Kagoshima, Japan.
Phylogenetic analysis based on 16S rRNA gene sequences of the novel isolates indicated a relationship to a symbiotic bacterial clone of the polychaete Osedax japonicus and these bacteria appear to represent a novel species of the genus Neptunomonas. Expand
Enzymatic Properties and Nucleotide and Amino Acid Sequences of a Thermostable β-Agarase from the Novel Marine Isolate, JAMB-A94
A gene, agaA, for a novel β-agarase from the marine bacterium JAMB-A94 was cloned and sequenced and showed 37–66% identity to those of known agarases in glycoside hydrolase family 16. Expand
Molecular evidence that deep-branching fungi are major fungal components in deep-sea methane cold-seep sediments.
The fungi of the Dikarya may play a role in the biodegradation of lignin and lignIn-derived materials in deep-sea, because the characterized fungal species related to the frequent phylotypes within the Dkarya have been reported to possess an ability to degrade lign in. Expand
Methylomarinovum caldicuralii gen. nov., sp. nov., a moderately thermophilic methanotroph isolated from a shallow submarine hydrothermal system, and proposal of the family Methylothermaceae fam. nov.
A novel methane-oxidizing bacterium, strain IT-9(T), was isolated from a shallow submarine hydrothermal system occurring in a coral reef in Japan and represents a novel species of a new genus, for which the name Methylomarinovum caldicuralii gen. nov. is proposed. Expand
Loktanella cinnabarina sp. nov., isolated from a deep subseafloor sediment, and emended description of the genus Loktanella.
On the basis of biochemical features and 16S rRNA gene sequence comparison, strain LL-001(T) is considered to represent a novel species of the genus LokTanella, for which the name Loktanella cinnabarina sp. Expand
Microbulbifer agarilyticus sp. nov. and Microbulbifer thermotolerans sp. nov., agar-degrading bacteria isolated from deep-sea sediment.
Nine agar-degrading strains isolated from deep-sea sediment in Suruga Bay and Sagami Bay and off Kagoshima, Japan were found to be closely affiliated with members of the genera Microbulbifer and Thalassomonas. Expand
