FIELD: chemistry.
SUBSTANCE: group of inventions relates to microbiology, namely to novel phosphate-solubilizing strains, as well as to composition and methods for increasing the availability of phosphate for plant uptake. Strains are proposed Penicillium bilaiae NRRL B-50776, NRRL B-50777, NRRL B-50778, NRRL B-50779, NRRL B-50780, NRRL B-50781, NRRL B-50782, NRRL B-50783, NRRL B-50784, NRRL B-50785, NRRL B-50786, NRRL B-50787 and NRRL B-50788 for the conversion of insoluble phosphate to a soluble form of phosphate. Also, strains are used to coat the seed of a plant.
EFFECT: proposed strains of Penicillium bilaiae are introduced into the soil in the form of inoculum and plants are grown, thereby increasing the availability of phosphorus and enhancing phosphorus uptake by plants.
