Halobacteria: The Evidence for Longevity
W.D. Grant, Renia T. Gemmell, Terry J. McGenity August 2, 1998 Extremophiles v3 p279-287

This review article discusses the diverse populations of halophilic microorganisms supported by ancient subterranean salt deposits called evaporates. The article begins by offering a brief introduction to the taxonomy and phylogeny of halobacteria. Subsequent topics include halite precipitation and the genesis of evaporite deposits, isolation of ancient microorganisms, molecular evidence for long-term dormancy of halobacteria, and the case for longevity.
