MICROFLORA OF SALIFEROUS RAW MATERIALS OF THE SOUTHERN REGION OF KAZAKHSTAN
The microorganisms adapted to existence in extreme conditions of the environment quickly adapt to changes of salinity of the environment. Microflora of the Southern region of Kazakhstan is affected by such factors as high salinity, quantitative and qualitative characteristics of saliferous raw materials. Samples of saliferous raw materials have been selected from the Dzhaksy-Klychsk field of lake salts and Bugazhayla’s field of Suzaksky district of the Turkestan region. Samples of saliferous raw materials, are characterized as sulfate-sodium, galitny, galitno-sulfate and sodium salts. Microflora of saliferous raw materials of the Aral Sea selected from the Southern basin, Dzhaksy-Klych and Bugazhayla fields consists of heterotrophic microorganisms in number of 104 CFU/g and enterobakteriya in 103 CFU/g. Micromycetes in number of 104 CFU/g are revealed only in tests of saliferous raw materials of Bugazhayla. 10 cultures of microorganisms have been isolated which dominating part representatives of genus – Micrococcus, Bacillus, Pseudomonas. Are presented to Enterobakteriya by one look – Enterobacter sp. Micromycetes are presented by the genus Aspergillus, Mucor, Penicillium and Fusarium. The halorezistent of the microorganisms isolated cultures to various concentration of NaCl was studied. It is shown that the cultures of M.luteus, Bacillus sp, Aspergillus sp., Penicillium sp. and Fusarium sp. were rezistent to 17-20 % of salts concentration.
