引言近几年来,在轮生放线菌中,发现很多抗菌素:其中已知的有链霉素(Streptomycin),紫霉素(Viomycin),新霉素(Neomycin),新抗菌素有轮生白丝菌素(Netropsin),五霉素(Pentamycin),丝裂霉素(Mitomycin),以及目前已经投入生产的抗滴虫霉素(Trichomycin)。尤其值得注意的是,这些菌所产生的抗菌素,对格兰氏阳性、阴性细菌、分枝杆菌、酵母、真菌、螺旋体、立克次氏体、大型病毒、肿瘤细胞都有作用,因此,这一类群的放线菌引起了各国学者们普遍的重视。在大量的筛选工作中,如果早期能对该类放线菌进行分类鉴定,对于尽快找出所需要 INTRODUCTION In recent years, many antibiotics have been found in actinomycetes: Among them, Streptomycin, Viomycin, Neomycin, Netropsin, Pentamycin, Mitomycin, and Trichomycin that are currently in production. Of particular note is that these bacteria produce antibiotics that have an effect on Gram-positive, -negative bacteria, mycobacteria, yeast, fungi, spirochetes, rickettsia, large viruses, and tumor cells, A group of actinomycetes caused widespread attention of scholars from all over the world. In a large number of screening work, early identification of such actinomycetes classification, as soon as possible to find out what is needed
