Isolation and Characterization of Salt-Tolerant Bacterial Strains in Salt-Affected Soils of East Anatolian Region

Abstract

In the current study, 18 salt-tolerant bacteria were isolated from salt-affected soil in the east Anatolian region. The obtained isolates were identified and characterized by conventional (morphology, physiology, and biochemical tests) and molecular techniques 16 rDNA. Among 18 sequenced isolates, 6 Bacillus, 1 Halomonas, 2 Halobacillus, 2 Zhihengliuella, 2 Oceanobacillus, 1 Virgibacillus, 1 Staphylococcus, 1 Thalassobacillus, 1 Exiguobacterium were identified with high similarity to previously identified strains in the literature. According to the results obtained, investigated bacterial strains have high salt tolerance and significant enzyme activities that can improve soil nutrient cycling and fertility. To the best of our knowledge, the current article is the first study in evaluation and diversity of potential halophlic/halotolerant bacterial strains in salt-affected soils of the east Anatolian region.
