    摘要: Antibiotics RK-1061s having a novel chemical structure and a method of production thereof. They have a structural formula represented by general formula(I) wherein A represents R1 or R1CH(OR2)CH2. R2 represents 3-methylglutarie acid residue and R3 represents a sulfate group or a hydrogen atom. The process comprises culturing a ray fungus belonging to the genus Streptomyces and isolating RK-1061s from the culture. Streptomyces sp. SN-1061Ms (FERM BP-5800) is capable of stably producing RK-1061 at a high productivity. 1
