영문 초록

Streptomyces minoensis DMCJ-144 isolated from soil produces the alpha-amylase inhibitor. Optimum culture conditions for alpha-amylase inhibitor production of the strain were determined in this experiment. The optimum composition of the culture medium was studied by supplementing various carbon sources, nitrogen sources, vitamins, and metal salts to the basal medium containing 1% glucose, 0.1% asparagine, 0.005% MgSO4.7H2O, 0.005% K2HPO4, 0.005% NaCl. Other culture conditions such as the culture temperature, initial pH of the medium, aeration, and culture time were also investigated. When the strain was cultured in a 100ml flask containing 20ml of 2% glucose, 0.5% beef extract, 0.0002% riboflavin, 0.0002% thiamine. HCl, 0.01% ZnCl2, 0.005%MgSO4 .7H2O, 0.005%CuSO4.5H2O, 0.005% K2HPO4, 0.005% NaCl, pH 7.2, 180 rpm at 30oC, the maximum production of the alpha-amylase inhibitor was observed after 5 days of the cultivation.
