This study aims at unraveling the bacterial biodiversity of Hail soil to establish a baseline study that contributes to harnessing these bacteria in applications that benefit human beings. We collected two groups of soil samples; one group of the models contained wheat roots, and the second group was free of roots. Bacteria were isolated from these soils, DNA was extracted, 16srRNA from different isolates was amplified and sequenced, and the phylogeny tree was analyzed. The taxonomic relationship indicated that the isolates obtained were belonging to Proteobacteria, Actinobacteria, and Firmicutes. The bacteria affiliated with Proteobacteria’s phylum were Stenotrophomonas, Klebsiella, Azospirillum, Calidifontimicrobium. Firmicutes include Bacillus and Actinobacteria represented by Nocardioides. The genera Bacillus, Stenotrophomonas, Calidifontimicrobium, and Nocardioides were associated with wheat's rhizosphere while the others live free in the soil. The study concluded that Hail soil is a pool of bacteria affiliated to different phyla; they share genetic traits, tolerate harsh environmental conditions that lead them to play different crucial roles in the environment, and may contribute to all aspects of human life harnessed adequately. More studies using housekeeping genes, "omics" approaches, and studies examining these isolates’ ability to withstand extreme environmental conditions are recommended to view more insights about these bacteria.
