Abstract
A method for preparing cholesterol oxidase, comprising the steps of: A. growing a cholesterol oxidase producing microorganism in a medium comprising a nontoxic concentration of nonionic surfactant to yield extracellular cholesterol oxidase; and B. separating the extracellular cholesterol oxidase from the medium. Preferably, cholesterol oxidase is prepared from a growth medium of Nocardia cholesterolicum species NRRL 5767 or 5768 which contains cholesterol, a suitable derivative of cholesterol or a 3-.beta.-hydroxy sterol as a cholesterol oxidase inducer and a nonionic surfactant in a concentration which is not toxic to said bacterium, which does not produce decomposition products in concentrations sufficient to be toxic to said bacterium, and in sufficient concentration to produce extracellular enzyme.
