RESUMEN: El uso de enzimas a nivel industrial es económicamente viable si éstos son estables bajo las condiciones del proceso y pueden ser reutilizados, lo cual puede lograrse mediante inmovilización en un soporte apropiado. Materiales inorgánicos porosos como las sílicas son buenos candidatos como soporte ya que presentan alta resistencia mecánica y térmica, facilitan el flujo y son biodegradables. Se muestra la eficiencia de sílica con porosidad controlada como soporte para inmovilización de lactasa. Este material es sintetizado partiendo de fuente de sílica barata, en presencia de surfactante catiónico y acetato de etilo que permiten modular el tamaño de poro.
ABSTRACT: The industrial use of enzymes is feasible only when these are stable under the process conditions and they can be used several times. The immobilization in an appropriate support can help to achieve those goals. Inorganic porous materials such as sílica are good candidates as support since they present high mechanical and thermal resistance; high flow rates and they are biodegradable. We use silica with controlled mesoporosity for a efficient immobilization of lactase. This material is synthesized by using sodium silicate as a source of silica and cationic surfactant and ethyl acetate for modulating the pore size.
