Abstract
Abstract Antibiotic saccharocins of the formula ##STR1## wherein R is hydrogen (saccharocin) or hydroxyl (3'-oxysaccharocin) are produced by culturing a microorganism belonging to the genus Saccharopolyspora, for example Saccharopolyspora sp. AC 3440 FERM-P No. 6238, in a conventional nutrient medium, and separating the thus-produced saccharocins from the cultured medium. The noval saccharocins exhibit anti-bacterial activity against Gram negative bacteria.
