PGPY Novel nitrogen-fixing bacteria Cryptococcus podzolicus PGPY and use thereof

摘要

The present invention relates to a novel nitrogen-fixing organism Cryptococcus podzolicus PGPY and its use, and more particularly to a novel nitrogen-fixing organism Cryptococcus podzolicus PGPY deposited at KACC 93288P at the National Institute of Agricultural Science and Technology (KACC) , A plant growth promoting composition containing the strain or the culture as an active ingredient, and a method for promoting plant growth using the strain. The strain of the present invention can supply a nitrogen source to a plant having nitrogen fixation ability and can continuously promote and enhance the growth of the plant in the soil. Accordingly, the strains, compositions and methods of the present invention can be used to increase the yield and improve the quality of the crop even if the use of chemical fertilizer is not performed in the farmhouse. In addition, the problem of soil contamination due to the use of chemical fertilizer It is expected that it will contribute greatly to resolve.
