Abstract

METODO DE RETENCION DE NAD(P) (H) EN ESTADO NATIVO CON MEMBRANAS DE ULTRAFILTRACION NO CARGADAS. COMPRENDE INTRODUCIR EN EL REACTOR DE FUNCIONAMIENTO CONTINUO PARA UNA SINTESIS QUIMICA ENZIMATICA, LOS CO(ENZIMAS) NAD(P) (H) TANTO EN FORMA OXIDADA COMO REDUCIDA, INCLUYENDO EN EL MEDIO DE REACCION POLIETILENOIMINA QUE HACE QUE TANTO LAS CO(ENZIMAS) COMO EL POLIMERO SEAN RETENIDOS POR MEMBRANAS DE ULTRAFILTRACION NO CARGADA CON UN LIMITE DE EXCLUSION INFERIOR AL PESO MOLECULAR DE LA POLIETILENOIMINA. APLICACION EN LA INDUSTRIA QUIMICA, Y EN ESPECIAL, EN SINTESIS ORGANICA VIA ENZIMATICA.
