K. Gerth et al., RATJADON - A NEW ANTIFUNGAL COMPOUND FROM SORANGIUM-CELLULOSUM (MYXOBACTERIA) - PRODUCTION, PHYSICOCHEMICAL, AND BIOLOGICAL PROPERTIES, Journal of antibiotics, 48(9), 1995, pp. 973-976
An antifungal activity, ratjadon, was detected in the culture broth of
Sorangium cellulosum (Myxococcales) strain So ce360. The metabolite w
as quantitatively bound to the adsorber resin XAD-16, which was added
to the medium at the beginning of the fermentation. The antibiotic spe
ctrum was narrow, but some important phytopathogenic fungi, especially
species of Oomycetes, were inhibited at very low concentrations.
