MICROBIOTA IN AREAS OF SOUTH ARAL SEA REGION

Microbial diversity in extreme areas attracts attention of many scientists (Кашнер, 1981; Константинова, 2009; Ventosa, 1998). One of such extreme areas is internationally acclaimed Aral Sea region and neighbouring territories, characterized by excessive aridity and salt accumulation and residual concentration of pesticides. It is proved that the natural microbiota under analysis contains sporogenous, ammonifying and oligonitrophilic microorganisms, which adapt to high temperatures, high salinification level and residual concentration of pesticides. In cultivated soil, where humus content increases, nitrate bacteria and denitrifying agents are detected. Azotobacter strains are allocated, which are resistant to pesticide mix (chlorpyrifos + Cypermethrin 500/50 g/l).
