A high number of culturable bacteria of the genus Streptomyces (7.84 ± 0.9) × 10 CFU/g was revealed in the actinomycete community of lake sapropel of OOO TPK Kamskiy Sapropel (Naberezhnye Chelny, Republic of Tatarstan, Russian Federation). A total of 14 strains of streptomycetes were isolated in pure culture, growing in a wide range of temperatures and sodium chloride content, possessing hydrolytic, antibiotic and urease activity, capable of biofilm growth, changing the rheological characteristics of the culture fluid when growing on crude oil (Δσ interfacial tension up to 23 mN/m). The ability of streptomycetes to degrade oil n-alkanes with a chain length of C−C was revealed; the addition of starch to the medium activated this process. This makes streptomycetes promising agents both for use in biotechnologies for enhancing oil recovery and in the creation of biopreparations for cleaning soils from oil and oil products.
