Bacillus lichemiformis Kll, a plant growth promoting rhizobacterium was reported as a producer of auxin, siderophore, as well as antifungal cellulase under some culture conditions. In vitro test, B. licheniformis Kll represented excellent antagonistic ability against Fusarium oxyspoum (KACC 40037), and showed broad spectrum against other phytopathogenic fungi. B. licheniformis Kll had cellulolytic activity toward not only carboxymethyl-cellulose (CMC) but also insoluble cellulose, such as fungal cell wall cellulose, filter paper (Whatman No. 1), and Avicel. In addition, we confirmed antifungal substance production by butanol-extract methods. The strain produced optimally the antifungal substance when it was cultivated at pH 9.0, 30${\circ}$C for 4 days on nutrient medium. The biological control mechanisms of B. lichemiformis Kll were caused by antifungal substance, cellulase and siderophore against phytopathogenic fungi.
