 note = {The search for life in extreme environments of the Earth's biosphere is a frontier to bridge conventional bio/ecology and exo/astrobiology. This communication reviews the extremophilic microbial life from the selected 'biospheric edges', Antarctica and deep subsurface of a hydrothermal vent field (sub-vent). Antarctica and sub-vents house brine (high salt) habitats and halophilic microorganisms (Naganuma, SUR Symposium 2002). In addition to halophiles, a psychrophilic (cold-loving) bacterium of the well-known stress-resistant genus Deinococcus was isolated from the South Pole snow, where UV and other radiations are hostile to other life forms. The Deinococcus species have been characterized as radiation-, UV-, dryness- and/or mutagen-resistant as well as thermo-/psychrophilic. A novel (thermophilic and anaerobic) Deinococcus strain was recently found in a deep sub-vent that represents the no-light, no-O2 (anaerobic) and high-temperature condition. These Deinococcus strains having diverse tolerability envisage an aspect of diversity and potential of the Earth's life and facilitate the capability of exobiological exploration., 資料番号: AA0045438018},
