title: [Ion-exchange chromatography on cholesterol oxidase from Actinomyces lavendulae on a Biocarb-type carboxyl cationite].
abstract: Reversible sorption on the Biocarb-D carboxyl cationite of cholesterol oxidase extracted from the mycelium of Actinomyces lavendulae was examined. Sorption at pH 5.0 and desorption at pH 5.5 maintained 80% of the enzyme activity and increased seven-fold the specific activity as calculated per protein. By gel chromatography on Sephadex G-150 it was shown that the process was accompanied by a significant decrease in the number of inactive proteins.
