ABSTRACT:
The invention refers to an individual antibiotic substance selected from the group consisting of Teichomycin A.sub.2 factor 1, Teichomycin A.sub.2 factor 2, Teichomycin A.sub.2 factor 3, Teichomycin A.sub.2 factor 4 and Teichomycin A.sub.2 factor 5 in substantially pure form, and to the method of producing them by recovery from Teichomycin A.sub.2, a known antibiotic substance, by means of high-efficiency chromatographic methods. The single pure Teichomycin A.sub.2 factor 1, Teichomycin A.sub.2 factor 2, Teichomycin A.sub.2 factor 3, Teichomycin A.sub.2 factor 4 and Teichomycin A.sub.2 factor 5 are biologically distinguishable from Teichomycin A.sub.2 in that they have a higher degree of antibiotic activity against susceptible microorganisms.
