Abstract

SE PRESENTA UN METODO PARA SEPARAR LOS COMPONENTES DE UN MEDIO LIQUIDO DE CULTIVO DE CELULAS QUE CONSISTE EN MEZCLAR EL MEDIO DE CULTIVO CON UN PRIMER MATERIAL EN PARTICULAS CARGADO, Y OPCIONALMENTE CON UN SEGUNDO MATERIAL EN PARTICULAS CARGADO PORTANDO UNA CARGA OPUESTA A LA DEL PRIMERO. EL MATERIAL EN PARTICULAS FORMA UNA SUSPENSION DE MATERIA EN EL MEDIO Y DESPUES SE RECUPERA LA MATERIA EN SUSPENSION MEDIANTE FILTRACION POR MEMBRANA. EL METODO PERMITE UN AUMENTO DE LA VELOCIDAD DE FLUJO A TRAVES DEL FILTRO DE MEMBRANA Y UN AUMENTO EN LA RECUPERACION DEL PRODUCTO.
