ANTIBIOTIC A-4696 FACTOR G AND GROWTH-PROMOTING COMPOSITIONS;ACTINOPLANES MISSOURIENSIS ATCC 31681

摘要

Glycopeptide antibiotic A-4696G is produced by culturing Actinoplanes missouriensis mutant strain ATCC 31681 under submerged aerobic fermentation conditions, and is recovered from the fermentation broth by resin adsorption and chromatographic purification. A-4696G inhibits the growth of bacteria pathogenic to man and animals and also enhances the growth of ruminants by increasing feed utilization.
