The glycopeptide 31,177 RP is prepared by cultivating under aerobic conditions in an aqueous nutrient medium Streptomyces calidus DS 26,320 (NRRL 8141), a hitherto unknown microorganism. 31,177 RP is of interest as an inhibitor of glyco-hydrolases, e.g. the amylases, the maltases or the saccharases, particularly those of the digestive tract. |
