An antifungal activity, ratjadon, was detected in the culture broth of Sorangium cellulosum (Myxococcales) strain So ce360. The metabolite was quantitatively bound to the adsorber resin XAD-16, which was added to the medium at the beginning of the fermentation. The antibiotic spectrum was narrow, but some important phytopathogenic fungi, especially species of Oomycetes, were inhibited at very low concentrations.
