Abstract

Preliminary study on antagonistic activity of biocontrol bacterium Brevibacillus brevis ZJY-1 wasmade by analyzing the inhibitory effect of cellular extraction and cell-free supernatant to mycelium growth and conidial spore germination of Fusarium oxysporium f. cucumerinum. The results showed that the growth of Fusarium oxysporium f. cucumerinum was inhibited mainly by metabolites excreted outside by the strain. In medium contained with cell-free supernatant,Mycelium growth of Fusarium oxysporum f. cucumerinum was obviously affected compared with that cultured in check and cellular extraction-contained medium. The metabolites derived from supernatant could evidently inhibit germination and tube growth of conidia, the inhibit rate was up to 96.0% and 82.0% respectively.[Ch, 3 fig. 2 tab. 16 ref.]
