Patent number: 5049495Abstract: High titers of polyether antibiotics are obtained in a fermentation broth by inoculating a nutrient fermentation broth with a microorganism capable of producing a polyether antibiotic. Growth of the microorganism is established in the broth by incubating the inoculated broth at a physiologically acceptable temperature until pH of the broth begins to rise upon establishment of growth of the microorganism. A free fatty acid then is fed into the broth to achieve and maintain a free fatty acid concentration in the broth of about 0.1% by weight or greater but less than a level at which the free fatty acid is toxic to the microorganism. The free fatty acid is fed into the broth during the remainder of fermentation at about a rate at which the free fatty acid is consumed by the microorganism, to product high titers of the polyether antibiotic.Type: GrantFiled: May 29, 1986Date of Patent: September 17, 1991Assignee: International Minerals & Chemical Corp.Inventor: Guido M.
