- Abstract
Deserts represent extreme environments for microorganisms, and conditions such as high soil salinity, nutrient deficiency, and increased levels of UV radiation make desert soil communities of high biotechnological potential. In this study, we isolated, sequenced, and assembled the genomes of Bacillus safensis strains BcP62 and Bcs93, to which we performed comparative genome analyses. Using the DDH and ANI of both strains with the available B. safensis genomes, we identified three potential subspecies within this group. Intra-species core genome phylogenetic analysis did not result in clustering genomes by niche type, with some exceptions. This study also revealed that the genomes of the analyzed strains possessed plant growth-promoting characteristics, most of which were conserved in all B. safensis strains. Furthermore, we highlight the genetic features of B. safensis BcP62 and Bcs93 related to survival in the Merzouga desert in Morocco. These strains could be potentially used in agriculture as PGPB in extreme environments, given their high tolerability to unfavorable conditions.
