Abstract

By adding a specific amine in culturing under aerobic conditions actinomycetales capable of producing phleomycin group antibiotics, which have been inoculated into a nutrient medium to produce antitumor phleomycin group antibiotics, it is possible to obtain specific phleomycin group antibiotics having a side chain structure corresponding to said amine. The phleomycin group antibiotics thus produced are collected from the culture medium in a conventional way.
