Abstract

PROCEDIMIENTO PARA LA PREPARACION DE BIOCATALIZADORES DE ACTIVIDAD ENZIMATICA.COMPRENDE LAS SIGUIENTES ETAPAS; A) REVESTIMIENTO DE PARTICULAS DE UNA MATERIA MINERAL RIGIDA Y DENSA CON UNA CAPA DE QUITOSAN, CONSTITUYENDO EL SOPORTE DEL CATALIZADOR; B) ESTABILIZACION POR MEDIO DE UN REACTIVO BIFUNCIONAL DE LAS PARTICULAS REVESTIDAS; Y C) FIJACION QUIMICA DE UNA ENZIMA SOBRE EL SOPORTE ASI TRATADO. EL REACTIVO BIFUNCIONAL UTILIZADO PARA LA ESTABILIZACION DE LAS PARTICULAS REVESTIDAS DEL SOPORTE ES ALDEHIDO GLUTARICO, A UN TEMPERATURA DE 15JC Y PH COMPRENDIDO ENTRE 2 Y 8EN SOLUCION TAMPON. LA DURACION DEL TRATAMIENTO DEPENDEN DE LA CONCENTRACION EN ALDEHIDO GLUTARICO, NO SIENDO MENOR A 31 MINUTOS. EL SOPORTE DE CATALIZADOR SE ELIGE ENTRE LAS PARTICULAS O ESFERILLAS POROSAS DE GEL DE SILICE, DE OXIDO METALICO O DE CERAMICA.TIENEN APLICACION EN LECHO FLUIDIZADO O EN LECHO FIJO.
