This article explores species diversity of actinomycetes isolated from soils of Northern Kazakhstan. Most of the selected strains of actinomycetes possess cellulolytic activity in the natural conditions of Northern Kazakhstan. 19 selected strains of actinomycetes were subjected to genomic analysis by growth promoting and cellulolytic properties in relation to crops. The study revealed that actinomycetes belonging to the genus Streptomyces dominate in the soils of Northern Kazakhstan.
Species such as S. cirratus, S. parvus and S.hantholiticus are common in saline soils; in dark chestnut soils – S. sindensis, S. microsporus, S. badius, S. pratensis, S. staurosporininus, S. griseus; in chernozems – S. ambofaciens, S.auratus, S. natalensis
and S. platensis. The isolated strains of actinomycetes will be utilized to create biological products used to decompose plant residues in the soil in order to increase its fertility.
