摘要

PURPOSE: A novel Streptomyces sp. strain is provided to ensure excellent antibacterial activity and insecticidal ability with eco-friendly farming. CONSTITUTION: A novel Streptomyces sp. A1022(microorganism deposit number: KACC91521P) has excellent antibacterial and insecticidal activity to plant pathogen and agricultural pest. A method for culturing the Steptomycess sp. comprises: a step of inoculating the Streptomyces sp in a medium containing 0.5-0.7 weight% of soybean meal, 0.3-0.4 weight% of yeast extract, 1.5-1.8 weight% of glucose, 0.05-0.1 weight% of CaCO_3, 0.05-0.1 weight% of MgSO_4, and remaining amount of distilled water; and a step of culturing at 150-300rpm of stirring speed, 29°C+/-1.0, and pH 6.5 of initial pH concentration for 96 hours.
