  • Method for producing aclacinomycins A, B, Y using Strepomyces lavendofoliae DKRS
    Patent number: 5484712
    Abstract: Disclosed herein are a novel strain of Streptomyces and a method for the production of aclacinomycins A, B, Y and aglycone thereof by cultivating the same. Streptomyces lavendofoliae DKRS(KCTC 0092BP) of the present invention is capable of producing aclacinomycins A, B, Y and aglycone with higher yield. Further, it is possible to selectively produce aclacinomycin A or Y by adjusting pH of the cultured broth of Streptomyces lavendofoliae DKRS to 4.4 or 4.6 with acetate buffer or hydrochloric acid, respectively.
