ABSTRACT OF THE DISCLOSURE The invention refers to an individual antibiotic substance selected from the group consisting of Teichomycin A2 factor 1, Teichomycin A2 factor 2, Teichomycin A2 factor 3, Teichomycin A2 factor 4 and Teichomycin A2 factor 5 in substantially pure form, and to the method of producing them by recovery from Teichomycin A2, a known antibiotic substance, by means of high-efficiency chromatographic methods. The single pure Teichomycin A2 factor 1, Teichomycin A2 factor 2, Teichomycin A2 factor 3, Teichomycin A2 factor 4 and Teichomycin A2 factor 5 are biologically distinguishable from Teichomycin A2 in that they have a higher degree of antibiotic activity against susceptible microorganisms.
