| Abstract: |
| Six plant pathogenic fungi including Botrytis cinerea, Jerusalem artichoke Sclerotium, Sclerotinia sclerotiorum, Phytophthora capsici, Fusarium solani, and Aphanomyces euteiches Dreehsler were used to determine the inhibitory activity of fermentation broth of halophilic bacteria against plant pathogenic fungi by paper disc diffusion method. In order to find halophilic strain with higher inhibitory activity against the plant pathogenic fungi, the tested strains were fermented to screen. The halophilic strains were with certain antagonistic activity against the growth of P.capsici by the disc diffusion assay. And the minimum inhibitory concentration (MIC) of fermentation broth of halophilic strains against P.capsici ranged from 9 to 12 mg/mL. |
