Dead Sea), hydrostatic pressures approaching 0. 1 MPa (deep sea) and temperatures exceeding 100°C (thermal vents or hot springs) or as low as –20°C (e. g. polar regions). Of the current studies on extremophiles, approximately 30,000 articles by the year 2007, almost two-thirds have been performed on org- isms adapted to outstanding temperatures, but much more attention has been paid to thermophiles than to psychrophiles. However, over the past 10 years, scientific publications on cold-adapted microorganisms have increased by a factor of ten. If one considers the extent of cold habitats, psychrophiles, i. e. cold-loving organisms, should largely lead in this comparison with thermophiles because a great proportion of the Earth’s biosphere never reaches temperatures above 5°C. Nearly three-quarters of the Earth is covered by oceans whose deep water masses, irrespective of latitude, are constantly between 2 and 4°C. | | 出版日期 | Book 20081st edition | | 关键词 | biodiversity; biosphere; ecosystem; ecosystems; environment; microorganism; microorganisms | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-540-74335-4 | | isbn_ebook | 978-3-540-74335-4 | | copyright | Springer-Verlag Berlin Heidelberg 2008 |
