The article studied the biological properties, destructive activity of microorganisms extracted from soil samples of Kyzylkairat, Belbulak contaminated with pesticides and showed the features of their use in soil bioremediation. The morphological, cultural, physiological and biochemical properties of microorganisms extracted from soil samples contaminated with pesticides have been studied. Strains of K2, K3, KC1, CK2, AK1 and AK5 exhibited high activity based on biological properties. The isolated strains have been studied for destructive activity, among which four strains have been selected and recommended for identification: Pseudomonas plecoglossicida K2, Bacillus aryabhattai K3, Solibacillus isronensis KC1 and Bacillus amyloliquefaciens CK2. Among the selected strains, Solibacillus isronensis KC1 and Bacillus amyloliquefaciens CK2 exhibited high growth in an environment with different concentrations of pesticides. Further study of these strains will enable their use in biotechnological processes, in the decomposition of pesticides and in soil bioremediation.
