抗生素PE—1047是从我国土壤中分离到的北里轮生链丝菌文生变种产生的。根据物理化学性质的研究,证实为十六元大环内酯抗生素,其活性物质的主要组分Ⅰ、Ⅴ相当于柱晶白霉素的A_3和A_1,本文所用样品为游离域。
The antibiotic PE-1047 is produced from the indigenous strains of Streptoverticillium spp. Isolated from soil in our country. According to the study of the physicochemical properties, 16-membered macrolide antibiotics were confirmed. The main components I and V of the active substance were equivalent to A_3 and A_1 of leucomycin. The samples used in this paper are free domains.
