36 strains of sulfur-oxidizing bacteria were isolated in
Southern Kazakhstan soda-saline soils and identified. Screening of
strains according bio-oxidation (destruction thiosulfate to sulfate) and
enzymatic (Thiosulfate dehydrogenises and thiosulfate reductase)
activity was conducted. There were selected modes of aeration and
culture conditions (pH, temperature), which provide optimum harvest
cells. These strains can be used in bio-melioration technology
