Extreme Halophiles Are Models for Astrobiology
Abstract
Studying extremophiles on Earth may provide helpful metrics in our search for life elsewhere in the universe. Species that thrive in hypersaline environments are among the most fascinating models for studying mechanisms of survival away from our planet. The genomic sequences of six such extreme halophiles and post-genomic studies of these microorganisms are providing insights about what it takes to live in environments that were once thought uninhabitable.

Within microbial mats of evaporated saline deposits, the concentration of carboxylic acids should be higher because microorganisms produce carboxyl-rich compounds to maintain metabolic functions in high salt.
“Within microbial mats of evaporated saline deposits (e.g., coastal lagoons, brackish and saline lakes), the concentration of carboxylic acids should be higher, because microorganisms usually produce carboxyl-rich compounds to maintain their metabolic functions in the presence of high concentration of salts (Fukuchi et al., 2003;DasSarma, 2006).”

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.
