Streptomyces violaceorectus produces a yellow-brown antimicrobial substance when cultivated on starch-potassium nitrate medium. The purified antimicrobial substance was active against Gram-positive, Gram-negative bacteria, and fungi. The solubility, characteristics, Rf values, minimum inhibiting concentrations, UV and IR spectra were studied. Elemental analysis was: carbon 37.94%, hydrogen 6.97%, nitrogen 7.50%, and oxygen 47.58%.
紫色直丝链霉菌在淀粉-硝酸钾培养基上培养时会产生一种黄棕色抗菌物质。纯化后的抗菌物质对革兰氏阳性菌、革兰氏阴性菌和真菌均有活性。研究了其溶解度、特性、比移值、最低抑菌浓度、紫外光谱和红外光谱。元素分析结果为：碳37.94%、氢6.97%、氮7.50%、氧47.58%。
