The transformation of cholesterol to cholest‐4‐ene‐3‐one has been investigated in the presence of toluene and carbontetrachloride using cells of Nocardia erythropolis (IMET 7185) immobilized by different methods. The adsorption on DEAE‐cellulose has been observed to be the most effective method. The stability of immobilized cells relating to cholesteroloxydase activity, transformation capacity, and the influence of water have been investigated.
