Marinitoga piezophila KA3 is a thermophilic, anaerobic, chemoorganotrophic, sulfur-reducing bacterium isolated from the Grandbonum deep-sea hydrothermal vent site at the East Pacific Rise (13°N, 2,630-m depth). The genome of M. piezophila KA3 comprises a 2,231,407-bp circular chromosome and a 13,386-bp circular plasmid. This genome was sequenced within(More)
The specificity of XbaI, SalI, HhaI, PstI, BamHI and SstI is relaxed in the presence of an organic solvent, such as 20% glycerol or 8% dimethylsulfoxide (DMSO). This alteration, very pronounced in some cases, requires an excess of enzyme, varies from one kind of enzyme to another and is highly dependent on the pH, the ionic strength, the nature of the(More)
Thermococcus barophilus is a hyperthermophilic, anaerobic, mixed heterotrophic, and carboxydotrophic euryarchaeon isolated from the deep sea hydrothermal vent Snakepit site on the mid-Atlantic ridge at a depth of 3,550 m. T. barophilus is the first true piezophilic, hyperthermophilic archaeon isolated, having an optimal growth at 40 MPa. Here we report the(More)
Transcriptomes were analyzed for two related hyperthermophilic archaeal species, the piezophilic Thermococcus barophilus strain MP and piezosensitive Thermococcus kodakarensis strain KOD1 subjected to high hydrostatic pressures. A total of 378 genes were differentially expressed in T. barophilus cells grown at 0.1, 40 and 70 MPa, whereas 141 genes were(More)
A novel hyperthermophilic, piezophilic, anaerobic archaeon, designated NCB100T, was isolated from a hydrothermal vent flange fragment collected in the Guaymas basin at the hydrothermal vent site named 'Rebecca's Roost' at a depth of 1997 m. Enrichment and isolation were performed at 100 °C under atmospheric pressure. Cells of strain NCB100T were highly(More)
Stress voiding (SV) in Cu vias and lines is investigated on 300 mm wafers after storage at temperatures ranging from 175/spl deg/C to 400/spl deg/C. Sensitivity to SV in lines decreases with metal pattern density. Microstructural analysis of Cu lines shows that voids are not only found at grain boundaries, but also within the grains, indicating bulk and/or(More)
The mitochondrial DNA from Xenopus laevis is a 17.4 x 10(3)-base-pair circular DNA molecule. The mapping of this DNA, using 19 different restriction endonucleases is reported here. The sites are as follows: 1 for BamHI, PstI, SacI, SalI, BalI; 2 for BglII, SacII, EcoRI, ClaI, 3 for XhoI, 4 for AvaI, XbaI, PvuII, 5 for HindIII, 6 for HhaI, BclI, HpaI, 10 for(More)
The limits of life of aerobic microorganisms are well understood, but the responses of anaerobic microorganisms to individual and combined extreme stressors are less well known. Motivated by an interest in understanding the survivability of anaerobic microorganisms under Martian conditions, we investigated the responses of a new isolate, Yersinia intermedia(More)
