Persistent microbial communities in #hyperarid subsurface habitats of the #Atacama Desert: Insights from intracellular DNA analysis https://academic.oup.com/pnasnexus/article/3/4/pgae123/7646996

"they proposed that the #microbes rely on water generated by the mineralogical change from #gypsum to #anhydrite. This change indeed leaves some amount of water in the environment and this water could be used by the #bacteria."

"In the upper 80 cm of playa sediments, microbial communities were dominated by #Firmicutes. Below 200 cm, a different microbial community was discovered, dominated by #Actinobacteria... this community might have colonized the soil 19,000 years ago, before being buried by playa deposits"
