ABSTRACT:
The known compound, 13.beta.-13-deoxy-22,23-dihydro-avermectin -B1a/B1b Aglycone is prepared microbiologically from cultures of the novel microorganisms (MA-6762, ATCC 55069, MA-6763 ATCC 55070) or the known microorganism Streptomyces lavendulae MA-6555 (ATCC 14159 or ATCC 55330). The compound is prepared by the biotransformation of 13-deoxy-22,23-dihydro avermectin B1a/B1b aglycone which oxidizes the 13-position and epimerizes the 13-position hydroxy group.
