Three hyperthermophilic sulfur-dependent heterotrophs were isolated from a shallow submarine hydrothermal system at an inlet of Kodakara-jima island, Kagoshima, Japan. The isolates grew at 60 to 97 degrees C, with the optimum temperatures at 85 to 90 degrees C. Sensitivity to rifampin and the existence of ether lipids indicated that the isolates are hyperthermophilic archaea. Partial sequencing of the genes coding for 16S rRNA showed that the three isolates are closely related to the genus…

Thermococcus waiotapuensis sp. nov., an extremely thermophilic archaeon isolated from a freshwater hot spring

An extremely thermophilic, sulfur-dependent archaeon, strain WT1, was isolated from a freshwater hot spring in the Lake Taupo area of North Island, New Zealand and proposed as a new species to be named Thermococcus waiotapuensis sp.

Pyrococcus horikoshii sp. nov., a hyperthermophilic archaeon isolated from a hydrothermal vent at the Okinawa Trough

Phylogenetic analysis of the sequences encoding 16S rRNA and glutamate dehydrogenase places the isolate with certainty within the genus Pyrococcus although there is relatively low DNA–DNA hybridization with described species of this genus.

Phenotypic Characterization, DNA Similarities, and Protein Profiles of Twenty Sulfur-Metabolizing Hyperthermophilic Anaerobic Archaea Isolated from Hydrothermal Vents in the Southwestern Pacific Ocean

DNA-DNA hybridization experiments revealed that there were two distinct homology groups, which correlated well with results obtained from sodium dodecyl sulfate-polyacrylamide gel electrophoresis of soluble whole-cell proteins, and these groups corresponded to the genera Pyrococcus and Thermococcus.

Growth Physiology of the Hyperthermophilic Archaeon Thermococcus litoralis: Development of a Sulfur-Free Defined Medium, Characterization of an Exopolysaccharide, and Evidence of Biofilm Formation

Phenotypic characteristics and 165 rDNA sequences of the isolates were similar to those of Thermotoga maritima andThermotoga neapolitana, both being hyperthermophilic bacteria isolated from hydrothermal fields, however, the isolate differed from these species in their minimum growth temperatures, utilization of some sugars, sensitivity to rifampicin and the effects of elemental sulfur and thiosulfate on growth.

Minimal Amino Acid Requirements of the Hyperthermophilic Archaeon Pyrococcus abyssi, Isolated from Deep-Sea Hydrothermal Vents

A minimal growth medium containing only nine amino acids and vitamins as the sole carbon and energy sources allowed the growth of Pyrococcus abyssi GE 5, a novel hyperthermophilic sulfur-metabolizing

Thermococcus fumicolans sp. nov., a new hyperthermophilic archaeon isolated from a deep-sea hydrothermal vent in the north Fiji Basin.

An extremely thermophilic archaeon, strain ST557T (T = type strain), was isolated from a deep-sea hydrothermal vent in the North Fiji Basin and Sequencing of the 16S rRNA gene revealed that it belongs to the genus Thermococcus, and it is proposed that this organism should be placed in a new species, TherMococcus fumicolans.

Cold Shock of a Hyperthermophilic Archaeon: Pyrococcus furiosus Exhibits Multiple Responses to a Suboptimal Growth Temperature with a Key Role for Membrane-Bound Glycoproteins

While the archaea do not contain members of the bacterial cold shock protein (Csp) family, they all contain homologs of CipA and CipB, which may represent a general prokaryotic-type cold response mechanism that is present even in hyperthermophilic archaea.

Phylogenetic analysis based on 16s rRNA sequence indicates that strain K1 is a new member of Crenarchaeota, the first strictly aerobic organism growing at temperatures up to 100°C.

Effect of carbon and nitrogen sources on growth dynamics and exopolysaccharide production for the hyperthermophilic archaeon Thermococcus litoralis and bacterium Thermotoga maritima.

The importance of effective cultivation methods for addressing physiological issues related to the growth of hyperthermophilic heterotrophs is illustrated, such that maltose utilization plots were biphasic and EPS production rose sharply at high dilution rates for both organisms.



Hyperthermus butylicus, a hyperthermophilic sulfur-reducing archaebacterium that ferments peptides

Its ether lipids, the absence of a mureine sacculus, the nature of the DNA-dependent RNA polymerase, and phylogenetic classification by DNA-rRNA cross-hybridization characterize H. butylicus as part of a novel genus of the major branch of archaebacteria comprising the orders Thermoproteales and Sulfolobales.

Regulation of Proteolytic Activity in the Hyperthermophile Pyrococcus furiosus

Under peptide-limiting conditions, levels of the 66-kDa protease (S66) were enhanced relative to those of other cell proteins, and preliminary evidence suggests that this protease is immunologically related to the eukaryotic multicatalytic proteinase complex (proteosome).
