Abstract
A group of sulfur-containing antibiotics, planothiocin-A, -B, -C, -D, -E, -F and -G, are produced by culturing Actinoplanes sp. A12526 in a nutrient medium, and separating the thus-produced planothiocins therefrom. The novel antibiotics have utility in therapeutic or prophylactic antibacterial compositions or feed additives for livestock, poultry or fish.
