Paper Abstract

Halobacteria cultured from salt deposits as old as 200 m.y. are assumed to be dormant halobacteria entombed in the brine inclusions that formed during deposition of the salt crystals. Hypersaline lakes may have also existed on early Mars. If so, evaporite minerals containing frozen brine inclusions may occur on the surface of Mars today. Analyses of samples of recently-deposited salt from Laguna Grande de la Sal in New Mexico revealed the presence of viable halobacteria. 16S rDNA from archae and eubacteria
