ANTAGONISTIC SOIL BACTERIUM BACILLUS SUBTILLIS AND BIOLOGICAL CONTROL AND PLANT GROWTH PROMOTION USING THE SAME

摘要

An antagonistic microorganism Bacillus subtilis and a method for biologically controlling plant pathogenic fungi and promoting plant growth by using the same microorganism are provided to inhibit growth of pathogenic fungi by producing antifungal materials, siderophore and cellulase, and promote plant growth by producing a plant growth stimulating hormone, auxin. The antagonistic microorganism Bacillus subtilis(KACC 91205P) produces siderophore, cellulase or auxin and is isolated from the soil. A composition for controlling Phytophtora capsici or Fusarium oxysporum or promoting plant growth comprises Bacillus subtilis(KACC 91205P) and further comprises at least one of antagonistic materials selected from siderophore and cellulase.
