Abstract: 1312541 The antibiotic tuberactinomycin-N TOYO JOZO KK 29 June 1971 [30 June 1970] 30451/71 Heading C2A The novel antibiotic tuberactinomycin-N, having the structural formula and physiologically acceptable acid-addition salts thereof, are produced by a method comprising aerobically cultivating Streptomyces griseoverticillatus var. tuberacticus No. N 6-130 (FERM P-619) in aqueous nutrient medium and then extracting tuberactinomycin-N from the culture medium. The micro-organism is a mutant of Streptomyces griseoverticillatus var. tuberacticus No. B-386 (NRRL 3482), from which it is obtained by treatment with nitrosoguanidine; the parent strain is distinguished from the mutant by its inferior growth on ureaglycerol agar, superior growth on a carrot plug and failure to cause coagulation of milk medium. Tuberactinomycin-N is isolated from the fermented broth filtrate by absorption on and elution from a column of cation exchange resin, silica gel or cellulose, concentrating the eluate and precipitating with a non-solvent, e.g. methanol or acetone. Alternatively it may be precipitated from an aqueous solution as an insoluble dye salt by adding a sulphonic acid dye, e.g. eriochrome violet, methyl orange or Alizarin Red S. Its salts may be prepared by adding an inorganic acid salt of triethylamine to the dye salt in methanol or acetone to precipitate the corresponding inorganic acid salt of the antibiotic.
