Abstract

PROBLEM TO BE SOLVED: To obtain an antimicrobial substance BE-44651 which has excellent antimicrobial effect against a variety of pathogenic microorganisms including MRSA and is useful in the field of medicines. SOLUTION: This microbial substance BE-44651 is represented by formula I (R is H or a group shown by formula II) produced by a microorganism in Actinomadura. The compound of formula I is produced by inoculating a microorganism of Actinomadura sp. A44561 or its modified strain to a culture medium containing nutrients at a pH of 4-8, culturing it, preferably at 26-36 deg.C for 68-240 hours and separating and purifying the product.

Although majurose and galactose were detected as the major sugar components of all the cells, arabinose and xylose were not detected and the sugar pattern was B type. Further, mycolic acid is not detected, the main menaquinone was MK-9 (H 6). Regarding phospholipids, phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine and unknown glucosamine-containing phospholipids were not detected, phosphatidylinositol mannoside and phosphatidylinositol were found, and the phospholipid type was PI type.
