NOVEL RAPAMYCIN PRODUCER

摘要

The present invention provides a novel culture which belongs to Actinoplanes (Ac tinoplanes sp. FERM BP-3832). This culture is capable of producing rapamycin more than ten times efficiently than the cultu res which have been reported (e.g., Streptomyces hygroscopicus ATCC 29253). The present invention provides a process for the prod uction of rapamycin which comprises cultivating Actinoplanes sp. FERM BP-3832 and thereafter isolating rapamycin fro m the fermentation mixture.
