STREPTOMYCES KASUGAENSIS GBA-0927, MICROBIAL PREPARATION CONTAINING THE SAME MICROORGANISM, AND METHOD FOR CONTROLLING FUSARIUM OXYSPORUM AND CLADOSPORIUM CUCUMERINUM USING THE SAME MICROBIAL PRE

摘要

PURPOSE: An antagonist microorganism, Streptomyces kasugaensis GBA-0927, a microbial preparation containing it, and a method for controlling Fusarium oxysporum and Cladosporium cucumerinum using the microbial preparation are provided, therefore Fusarium oxysporum and Cladosporium cucumerinum can be effectively controlled. CONSTITUTION: Streptomyces kasugaensis GBA-0927(KFCC-11218) capable of inhibiting Fusarium oxysporum and Cladosporium cucumerinum is isolated by the steps of: collecting soils from various regions; cultivating the soil samples in an agar medium; inoculating plant disease-causing bacteria and cultivating; and selecting a sample producing transparent circles. The method for controlling Fusarium oxysporum and Cladosporium cucumerinum comprises the steps of: cultivating Streptomyces kasugaensis GBA-0927(KFCC-11218) in a medium containing 15g of soy bean powder, 200g of glucose, 105g of ammonium sulfate, 5g of potassium phosphate and 25g of magnesium sulfate in 1 liter of distilled water under conditions of pH 7.0, 30 deg.C, 150 rpm and 0.5 vvm for 168 to 180 hours; preparing a microbial preparation containing an effective amount of the cultivated Streptomyces kasugaensis GBA-0927(KFCC-11218) medium; and treating plants with the microbial preparation.
