Psychrophilic enzymes: hot topics in cold adaptation
Open accessAbstract
More than three-quarters of the Earth's surface is occupied by cold ecosystems, including the ocean depths, and polar and alpine regions. These permanently cold environments have been successfully colonized by a class of extremophilic microorganisms that are known as psychrophiles (which literally means cold-loving). The ability to thrive at temperatures that are close to, or below, the freezing point of water requires a vast array of adaptations to maintain the metabolic rates and sustained growth compatible with life in these severe environmental conditions.

Tolerance to high and low temperatures involves the production of specific enzymes to maintain chemical reactions and changes to the lipid composition of membranes to maintain membrane fluidity.
“Tolerance to high and low temperatures involves the production of specific enzymes to maintain chemical reactions and changes to the lipid composition of membranes to maintain membrane fluidity (e.g., Feller and Gerday, 2003).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
