    Possible artefactual basis for apparent bacterial growth at 250 °C (reply) (1984)
    [s.l.] : Nature Publishing Group
    Nature 307 (1984), S. 740-740

    Notes: [Auszug] The conclusion of Trent et al. that no bacterial growth occurred in our experiments1 is not tenable because of crucial differences between the results of our work and theirs, and because of additional data not addressed by these authors. If the scores of morphologically diverse bacteria we observed ...

    Is the CH 4 , H 2 and CO venting from submarine hydrothermal systems produced by thermophilic bacteria? (1982)

    Notes: [Auszug] Submarine hydrothermal systems located along tectonic rifts and ridges off the Galapagos Islands and along the East Pacific Rise4'6 and the Gorda Ridge have been studied and sampled since 1977. Two groups of vents have been described: (1) cracks and small fissures which emit warm water (5-22 C) at ...

    Growth of ‘black smoker’ bacteria at temperatures of at least 250 °C (1983)

    Notes: [Auszug] The upper temperature limit of environments known to support life has rarely been reported as exceeding 100 C, although there have been reports of bacteria existing in hot waters at temperatures a few degrees above 100C37, or cultured at 105 C7. Only prokaryotic organisms are found in environments ...

    Initial microbiological response in lakes to the Mt St Helens eruption (1982)

    Notes: [Auszug] There are numerous oligotrophic sub-alpine lakes surrounding Mt St Helens (Fig. 1), which were dramatically altered by the 18 May 1980 eruption. Some lakes and streams were reshaped, new lakes and numerous hydrothermal seeps emerged. Aquatic environments in the blast zone received massive ...

    Legionella in aquatic habitats in the Mount Saint Helens blast zone (1983)

    Notes: Abstract Illnesses of undiagnosed etiology among researchers exposed to lakes and streams in the Mt. St. Helens blast zone after the 18 May 1980 eruption prompted us to determine the occurrence and potential virulence ofLegionella (Legionnaries' disease bacteria) in aquatic habitats near Mt. St. Helens during the summers of 1981 and 1982. Concentrations ofL. pneumophila, L. micdadei, L. gormanii, L. dumoffii, andL. bozemanii, determined by microscopic counts using direct immunofluorescent staining, ranged from 〈104 to 105 cells/l in lakes and rivers outside the Mt. St. Helens blast zone while the numbers ofLegionella in aquatic habitats inside the blast zone were from 105 to 107 cells/l.Legionella numbers were consistently highest in North Coldwater and Spirit lakes, which received water from hydrothermal seeps.Legionella pneumophila serogroups 4 and 6 were isolated from North Coldwater Lake in 1981 and from South Coldwater Creek in 1982, indicating that potentially virulent strains ofLegionella persist in aquatic habitats in the blast zone of Mt. St. Helens.

    The fine structure ofCristispira from the lamellibranchCryptomya californica conrad (1981)

    Notes: Abstract The fine structure ofCristispira from the lamellibranchCryptomya californica Conrad was examined by Nomarski differential interference, Hoffman modulation contrast, phase contrast, polarizing, and darkfield optics, which were useful for observing the motility, morphology, and organelles of livingCristispira within the crystalline style. Transmission electron microscopy studies of double-stained sections and negatively stained whole cells revealed details of the outer sheath, axial filament, and the protoplasmic cylinder. Hundreds of periplasmic flagella were observed, as well as membrane-bound vesicles and lipid accumulations in the protoplasm, which may help to explain the mutualistic relationship which seems to exist betweenCristispira spp. and their molluscan hosts. Also described are a dialysis method for producing concentrated populations of viableCristispira from the clam, and a minimal-salts medium for their short-term maintenance.
