[Natural variability of Actinomyces lavendulae, a producer of cholesterol oxidase].
Five variants of Actinomyces lavendulae differing in the morphology of their colonies were found when natural variability of this organism was studied. A correlation was established between the colony morphology of the variants and their activity of cholesterol decomposition. The variants forming colonies of the basic and folded type had the highest activity. A variant with an elevated activity of cholesterol oxidase was selected. In order to maintain the high activity of the culture, it is necessary to examine its variability and to select variants corresponding to the basic type in their morphology.
