Environmental temperature is one of the most important factors for the growth and survival of microorganisms. Here we describe a novel extremely halophilic archaeon (haloarchaea) designated as strain CBA1119(T) isolated from solar salt. Strain CBA1119(T) had the highest maximum and optimal growth temperatures (66 C-degrees and 55 (LC)-L-degrees, respectively) and one of the largest genome sizes among haloarchaea (5.1Mb). It also had the largest number of strain-specific pan-genome orthologous groups and unique pathways among members of the genus Natrinema in the class Halobacteria. A dendrogram based on the presence/absence of genes and a phylogenetic tree constructed based o nOrth oANI values highlighted the particularities of strain CBA111(T7) as compared to other Natrinema species and other haloarchaea members. The large genome of strain CBA111(T7) may provide information on genes that confer tolerance to extreme environmental conditions, which may lead to the discovery of other thermophilic strains with potential applications in industrial biotechnology.
