Sulfur-containing antibiotics planothiocin -A, -B, -C, -D, -E, -F, and -G, are prepared by culturing Actinoplanes sp. Al2526 (FERM-P No. 5063) and isolating the desired planothiocin or planothiocins from the resultant culture. The planothiocins can be made up into pharmaceutical compositions with a pharmaceutically acceptable excipient, or used as feed additives to promote growth in livestock, poultry and fish. |
