Abstract

L'invention est relative à un procédé de fermentation produisant de la cholestérol-estérase. Suivant l'invention, on fait croître une bactérie Nocardia cholesterolicum souche NRRL 5767 ou 5768, sur un milieu qui comprend un inducteur de cholestérol-estérase et de l'extrait de levure. La cholestérol-estérase présente des applications en chimie biologique, notamment à l'hydrolyse des esters cholestériques.
