| Abstract: | Bacillus subtilis KB-1111 and KB-1122 were studied to illustrate their phenotypic and biological properties. Comparison of KB-1111 with KB-1122
in morphology was carried out by microscopy and agar plate assays. Biological assay of the test strains showed that they may
possess different physiological pathways from those of reference strain ATCC6501. The assessment of antagonism against the
indicator fungi showed that both test strains had broad antifungal characteristics against eight phytopathogenic fungi. Of
those fungal species, Magnaporthe grisea P131, Sclerotinia sclerotiorum, and F. oxysporium exhibited high sensitivity to the test strains. |
