- 論文の詳細を見る
A brownish-orange crystalline antibiotic having acid-base-indicating property has been isolated from the culture filtrate of a strain of Streptomyces grown on a MgSO_4-rich medium. The mature aerial mycelium of this strain was gray and bore long straight chains of spores with smooth surface. Several taxonomic characteristics were investigated. The antibiotic, named A-60,had strong activity against Gram-positive bacteria amd weak activity against Gram-negative bacteria. Some physical and chemical properties of this antibiotic were investigated. The effect of MgSO_4 and other metal salts on production of the antibiotic was investigated. The productivity was accelerated by the addition of MgSO_4,MgCl_2,MnCl_2,FeSO_4,FeCl_2 or BaCl_2.
