Abstract
PURPOSE: To prepare 3-O-demethyl-fortimicin A, economically, by culturing a specific bacterium belonging to Micromonospora genus in a medium, and separating from the medium.
CONSTITUTION: Bacteria belonging to Micromonospora genus and capable of producing 3-O-demethyl-fortimicin A, e.g. Micromonospora olivoasterospora MK-70 (FERM-P No.1560), are cultured in a liquid medium for the cultivation of actinomycetes, esp. in anagitated deep-tank fermentor, at 25W40°C, under almost neutral conditions, and the accumulated 3-O-demethyl-fortimicin A is separated from the medium, e.g. by cation exchange resin adsorption, etc.
