FIELD: agricultural biotechnology.
SUBSTANCE: invention relates to the production of biological products that improve the mineral nutrition of plants in conditions of deficiency of mobile phosphorus in soils. Strain of actinomycete Streptomyces parvulus VKPM Ac-2177 is proposed, which has the ability to solubilize phosphorus. The Streptomyces parvulus LA2 strain was isolated from the soil and deposited at the National Bioresource Centre - All-Russian Collection of Industrial Microorganisms (BRC VKPM) of the National Research Centre Kurchatov Institute - GosNIIgenetika under the number Ac-2177.
EFFECT: strain is capable of releasing phosphate ions from insoluble and slightly water-soluble phosphates, and is compatible with biological fungicides – gliocladin (Trichoderma harzianum) and phytosporin (Bacillus subtilis).
