Abstract

Introduction: HALOPHILEs and halotolerant microorganisms are some of the extremophiles that are able to grow in medium containing sodium chloride and have adapted to life in salinity environments. HALOPHILEs bacteria in saline soils by maintaining the food chain, decomposition of organic matter and improvement of soil structure and fertility improve soil conditions.Materials and methods: In order to isolate the halotoletant bacteria, from the halophyte rhizosphere, four desert areas in Golestan province were sampled. To check the Extremophile of isolates, their resistance was tested for resistant to salinity, drought, temperature and PH. Also, plant growth promoting traits were measured.Results: From forty-five strains which were isolated, three strains (G3, G6 and G14) have demonstrated the ability of resistance to 35% SALT. Isolates G6 and G3 phosphate solubiliziation power of 301 and 201 ppm, respectively. Isolated G6 micrograms produced AUXIN 20.7 Mg/ ml. G14 and G6 grow at 50 °C, pH = 10 and osmotic potential -0 .7MPa. While G3 strain grows at 50 °C, pH = 7. 5 and osmotic potential 0.49. The three strains of the bacterial genera BACILLUS and PSEUDOMONAS, respectively.Discussion and conclusion: In this study, isolates due to the growth in concentrations of SALT and saturated SALT tolerance of extreme environmental conditions and are likely halotolerant or HALOPHILE bacteria and its potential for use in various fields of biotechnology including biotech, industrial enzyme production and biological fertilizers for saline soil improvement.
