Abstract EN
In this study the archaeal communities in extreme saline-alkaline soils of the former lake Texcoco, Mexico, with electrolytic conductivities (EC) ranging from 0.7 to 157.2 dS/m and pH from 8.5 to 10.5 were explored.
Archaeal communities in the 0.7 dS/m pH 8.5 soil had the lowest alpha diversity values and were dominated by a limited number of phylotypes belonging to the mesophilic Candidatus Nitrososphaera.
Diversity and species richness were higher in the soils with EC between 9.0 and 157.2 dS/m.
The majority of OTUs detected in the hypersaline soil were members of the Halobacteriaceae family.
Novel phylogenetic branches in the Halobacteriales class were detected in the soil, and more abundantly in soil with the higher pH (10.5), indicating that unknown and uncharacterized Archaea can be found in this soil.
Thirteen different genera of the Halobacteriaceae family were identified and were distributed differently between the soils.
Halobiforma, Halostagnicola, Haloterrigena, and Natronomonas were found in all soil samples.
Methanogenic archaea were found only in soil with pH between 10.0 and 10.3.
Retrieved methanogenic archaea belonged to the Methanosarcinales and Methanomicrobiales orders.
The comparison of the archaeal community structures considering phylogenetic information (UniFrac distances) clearly clustered the communities by pH.
