Abstract

The spatial distribution of halophilic microbial communities of saline soils and highly mineralized lakes in the arid regions of the Caspian Depression been studied. It is shown that the main components of microbial flora of the Terek-Kumskaya and Terek-Sulakskaya provinces are chemoorganotrophic bacteria of the genera Virgibacillus, Bacillus, Halomonas, and Salimicrobium from the phyla Firmicutes and Proteobacteria. The strains demonstrated the ability to produce catalase, protease, and amylase and sensitivity to 14 antibiotics from the groups of fluoroquinolones, cephalosporins, and macrolides. The findings are of scientific and practical interest for research on the spatial distribution of halophilic bacteria under arid conditions and their biotechnological significance.

里海低地干旱区的嗜盐微生物群落及其生物多样性

摘要

研究了里海De陷干旱地区盐渍土壤和高度矿化湖泊的嗜盐微生物群落的空间分布。结果表明，捷列克-Kumskaya和捷列克-Sulakskaya省微生物菌群的主要成分为下列属的细菌chemoorganotrophic Virgibacillus，芽孢杆菌属，盐单胞菌，并且Salimicrobium从门类厚壁菌门和变形菌门。该菌株显示出产生过氧化氢酶，蛋白酶和淀粉酶的能力，并对氟喹诺酮类，头孢菌素类和大环内酯类中的14种抗生素具有敏感性。这些发现对于研究干旱条件下嗜盐细菌的空间分布及其生物技术意义具有科学和实践意义。
