Abstract

NEW MATERIAL:L-Digitoxose having the following physical properties: Appearance. colorless prismatic crystal; melting point, 111W112°C; specific rotatory power, [α]D25=-37.3° (c=1.11, methanol); elemental analysis, C 48.47% (calc. value 48.46%), H 8.34% (calc. value 8.16%).
USE: Synthetic raw material of antibiotics, cardiotonic drugs, and other medicines. A sweetening agent.
PROCESS: For example, Micromonospora sp. KY11091 (FERM-P No.4458) (NRRL 11,289) is cultured in a seed medium at 30°C for 48 hours under agitation. The seed culturing liquid thus prepared is further cultured in a fermentation medium under aeration and agitation to obtain antibiotic substance DC-11, which is hydrolyzed with a hydrolyzing agent in water or in a mixture of water and an organic solvent to obtain the objective L-digitoxose.
