Abstract
A method for producing streptovaricin by culturing a streptovaricin producing strain in the presence of a nonionic adsorbent. This procedure substantially increases the production efficiency of the streptovaricin. A second embodiment wherein the streptovaricin producing strain is produced in the presence of fumaric acid or its water soluble salts to provide improvements in production efficiency is also disclosed.
