• Microbial stress-response physiology and its implications for ecosystem function. (2007, unknown): “At low temperature, lipid membranes can solidify (Methe et al. 2005) and ice crystals can rupture cell membranes (Rivkina et al. 2000), both potentially fatal.”
• Fungi in Antarctica (2007, background): “In biology low temperature is usually identified with subzero temperatures with a lower limit of ‐ 20C, below which no life processes persist ( Rivkina et al. 2000 ).”
• Temperature and substrates as interactive limiting factors for marine heterotrophic bacteria (2001, background): “Such excesses can, of course, be site-variable, as in the case of the subantarctic Marion Island lakes, where Robarts et al. (1991) found a lake enriched by seal feces to have high microbial activity, while an adjacent lake without seals did not.”
• Reproduction and metabolism at − 10°C of bacteria isolated from Siberian permafrost (2003, unknown): “At the low-temperature limit for life, metabolic and growth rates are low and individual metabolic processes are usually measured as proxies for cell division (Karl and Bossard, 1985a,b; 1986; Carpenter et al., 2000; Rivkina et al., 2000).”
• Earth's Icy Biosphere (2004, background): “Thin veins of liquid water between ice crystals could potentially provide a microbial habitat within apparently solid ice (Mader et al. 1992a, b; Price 2000), and studies of permafrost (Rivkina et al. 2000), surface snow (Carpenter et al. 2000), and frozen bacterial suspensions (Fig.”
• The thermal limits to life on Earth (2014, background): “…TS (°C) Comments Archaea −16.5 nd Methanogenesis in permafrost cores (Rivkina et al. 2007) Bacteria *−20 <−196 Microbial respiration in permafrost cores (Rivkina et al. 2000) Eukarya Unicellular algae *−8 nd Diatom N. frigida in brine channels (Thomas 2012) Yeasts *−20 <−196 Lichens −10a ≤80 Dark…”
• Bacterial Activity at −2 to −20°C in Arctic Wintertime Sea Ice (2004, background): “(3), and on a par with the temperature at which rates of acetate metabolism in permafrost were near the detection limit (41).”
• High-Pressure Biochemistry and Biophysics (2013, methodology): “Bacterial metabolic activity has been described at temperatures as low as −40 °C (Rivkina et al. 2000; Price and Sowers 2004; Pan-ikov and Sizova 2007; Collins et al. 2010) and a methanogen has been cultured at 122 °C under hydrostatic pressure (Takai et al. 2008).”
• Incorporation of DNA and Protein Precursors into Macromolecules by Bacteria at −15oC (2002, background): “The data reported here add to the growing body of evidence for metabolism under frozen conditions (6, 17 ).”
