Phylogenetic tree highlighting the position of the Natrinema altunense strain AJ2T relative to phylogenetically closely related type strains within the family Halobacteriaceae. These sequences were aligned on the SINA Online service [40] based on SILVA SSU/LSU databases. According to the best nucleotide substitution models found by the maximum-likelihood method in MEGA6 [41], the algorithm of the Jukes-Cantor model [42] was used to calculate the evolutionary distances in the neighbour-joining (NJ) method. Numbers at branch nodes refer to bootstrap values ≥ 50% (based on 1000 replicates). Halobacterium salinarum DSM 3754T (AJ496185) was used as an out-group.
