The present invention relates to a method of producing the antibiotics C-14919 E-1 and/or E-2 by cultivating an antibiotic C-14919 E-1 and/or E-2 producing strain of the genus Nocardia in a culture medium and accumulating said antibiotics. These antibiotics have a wide range of antibiotic activity and they are useful as germicides or disinfectants.
The invention relates to radioactively tagged Jomol, and its derivatives, diagnostic compositions, and pharmaceutical preparations containing such Jomol or its derivatives, as well as to products containing such Jomol and/or one of its derivatives and an adjuvant.
A novel Antibiotic C-15003 is produced by cultivating a microorganism of the genus Nocardia. The Antibiotic C-15003 is useful as an antifungal agent or an antiprotozoan agent.
The present invention is directed to a process for recovering the antibiotics produced by fermentation of Actinoplanes sp. ATCC 33076 or a producing mutant thereof, from a fermentation broth or a process stream, which comprises extraction of the antibiotics by a non-ionic surfactant or a cationic surfactant miscible with or dispersable in water and capable of dissolving the antibiotics, formation of two phases in the first of which the antibiotic and the surfactant are present together, and separation of the antibiotic from the surfactant by addition of suitable organic solvents.
