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

  title={Growth of ‘black smoker’ bacteria at temperatures of at least 250 °C},
  author={J. Baross and J. Deming},
Complex communities of thermophilic bacteria have been cultured from the 350 °C waters emanating from sulphide chimneys, or ‘black smokers’, at 21 °N along the East Pacific Rise1. Several of the bacterial communities were shown to grow rapidly at 100 °C and atmospheric pressure, producing methane, hydrogen gas and carbon monoxide. These gases are found in superheated vent water, having previously been attributed to abiogenic reactions. Before concluding that these ‘black smoker’ bacteria… Expand
At depths of about 2 600 m along the East Pacific Rise, sulfide chimneys or «black smokers» are emitting superheated fluids at temperatures of about 350°C into cold seawater. Dissolved in theseExpand
Growth of the extreme thermophile Sulfolobus acidocaldarius in a hyperbaric helium bioreactor
Results indicate that hyperbaric helium bioreactors will be important in the study of extremely thermophilic bacteria that are isolated from pressurized environments. Expand
A microbiological study of Guaymas Basin high temperature hydrothermal vents
Abstract Water samples and suspended particulate matter were collected from three high temperature (156–319°C) hydrothermal vents in the Guaymas Basin during July 1985, and were analysed for aExpand
High‐pressure—temperature bioreactor for studying pressure—temperature relationships in bacterial growth and productivity
Initial studies in this bioreactor of Methanococcus jannaschii, an extremely thermophilic methanogen isolated from a deep‐sea hydrothermal vent, revealed that increasing the pressure accelerated the production of methane and cellular protein by this archaebacterium at 90°C, and raised the maximum temperature allowing growth from 90 to 92°C.

Particulate DNA in Smoker Fluids: Evidence for Existence of Microbial Populations in Hot Hydrothermal Systems
Detailed sampling at one smoker site demonstrated not only the existence of significant levels of particulate DNA in the superheated smoker fluids but also the presence of an elevated microbial population in the buoyant plume 20 to 100 m above the smoker. Expand
Deep-sea smokers: windows to a subsurface biosphere?
The case for a subsurface biosphere based on an interdisciplinary view of microbial and geochemical analyses of Endeavour smoker fluids is offered, a case in keeping with rapidly evolving geophysical understanding of organic stability under deep-sea hydrothermal conditions. Expand

Ultrathin mycelia-forming organisms from submarine volcanic areas having an optimum growth temperature of 105 °C
The most extremely thermophilic organisms known to date have been isolated from continental volcanic areas1–3, and grow optimally between 70 and 85 °C. In the hope of finding organisms living atExpand
Is the CH4, H2 and CO venting from submarine hydrothermal systems produced by thermophilic bacteria?
Submarine hydrothermal vents are a major source of methane to the oceans1,2. The methane, as well as H2 and CO, are generally believed to result from degassing of the mantle or from abiogenicExpand
Methane and hydrogen in East Pacific Rise hydrothermal fluids
Recently discovered hydrothermal vents at 21°N on the East Pacific Rise are discharging turbid waters at up to 400°C; mixtures of the plumes with ambient seawater contain significant amounts ofExpand
CH4, H2, CO and N2O in submarine hydrothermal vent waters
Hydrothermal circulation systems of mid-ocean ridges profoundly influence the chemistry of the oceans and the oceanic crust1–3. This has been demonstrated for several major and minor constituents ofExpand
