A new species of the genus Actinomadura which belongs to the Actinomadura madurae group of Goodfellow et al. was isolated from soil collected in Togo, West Africa. Traditional taxonomic methods plus contemporary fatty acid analysis techniques were used to establish the position of this species. Both physiological characteristics and fatty acid composition differentiate this strain from previously described species. This culture produces a new polyether antibiotic. It is characterized by the production of white to pink aerial hyphae on a limited number of media. The aerial hyphae appear asporogenous, forming thick fibers and projections instead of true spores. The reverse side is a distinctive reddish orange. This organism is resistant to 5% NaCl and grows at temperatures between 20 and 45 degrees C. Whole cells contain meso-diaminopimelic acid, galactose, glucose, mannose, madurose, phosphatidylinositol, and diphosphatidylglycerol. The menaquinones detected were MK-9(H6) and minor amounts of MK-9(H8). The name proposed for this new species is Actinomadura fibrosa; the type strain is strain NRRL 18348.
从西非多哥采集的土壤中分离出了链霉菌属的一个新物种，该物种属于古德费洛等人的马杜拉放线菌群。采用传统分类方法和现代脂肪酸分析技术来确定该物种的分类地位。其生理特征和脂肪酸组成均使其与先前描述的物种有所不同。该菌株产生一种新的聚醚抗生素。其特征在于在有限数量的培养基上产生白色至粉红色的气生菌丝。气生菌丝似乎不产孢，而是形成粗纤维和突起，而非真正的孢子。背面为独特的红橙色。该菌对5%氯化钠具有抗性，在20至45摄氏度的温度范围内生长。全细胞含有内消旋二氨基庚二酸、半乳糖、葡萄糖、甘露糖、马杜拉糖、磷脂酰肌醇和二磷脂酰甘油。检测到的甲基萘醌为MK - 9(H6)和少量的MK - 9(H8)。这个新物种提议命名为纤维链霉菌；模式菌株为NRRL 18348菌株。
