The methods of oriented immobilization of lipases on a solid carrier - Silochrome C-80 have been developed. The resulting sorbents were tested in the process of obtaining biodiesel from cotton oil. It was shown that immobilized lipase on Silochrome C-80 with NH2 group has the highest transetrification ability and stability, while in sorbents with the enzyme immobilized with -COOH and -SH groups this value was 87 and 53%, respectively. Biocatalysis using an affinity sorbent of immobilized lipase with the –NH2 group has a high operational stability, which, after 240 hours of operation, retains more than 50%, and after 480 hours, 17% retains its initial activity.
