Lysobacter antibioticus HS124 isolated from pepper rhizosphere soil produced catechol type siderophore. Purified siderophore by Diaion HP-20 and silica gel column chromatography showed several hydroxyl functio nal groups adjacent to benzene rings by analysis of 1H NMR spectroscopy. The strain HS124 showed different activities to suppress Phytophthora capsici with different concentrations of exogenous Fe (III) in minimal medium where antifungal activity with 100 μM Fe (III) was approximately 1.5 times higher than in absence of Fe (III). Bacterial population in this Fe (III)-amended medium was also highest with 8.9×10<sup>8</sup> CFU ml<sup>-1</sup> which also corresponded to the strongest siderophore activity. When grown in rich medium (minimal medium with N, P<sub>2</sub>O<sub>5</sub>, K<sub>2</sub>O and glucose), HS124 exhibited approximately 2 times stronger antifungal activity compared to minimal medium. In pot trials, treatments of bacterial culture grown in rich medium with (C1) or without (C2) 100 μM Fe (III) exhibited a high protection of pepper plants from disease, compared to medium only with (M1) or without (M2) 100 μM Fe (III). Especially, treatment C1 showed the best disease control effect of about 70 %. Thus, the strain HS124 should be recommended as a potential biocontrol agent against P. capsici in pepper.
