Kazakhstan is one of the major oil producing and processing countries. Unfortunately, along with the growing volume of processed crude oil intensifies the problem of environmental pollution. In this context, the aim of this work was to study the role of microorganisms in the bioremediation of oil-contaminated loamy gray soils of South Kazakhstan. The studies were allocated 2 active strains of microorganisms Micrococcus luteus IS16 and Micrococcus varians IS41, which in vitro degraded 99.3% contributed by 2.0% kumkol oil. In real soil and climatic conditions of spontaneous microflora reduced content Kumkol oil by 39.6%, augmented microorganisms degraded 57.3% of oil, 92.8% of diesel fuel for 2 months.
