Resumen

En este artículo describimos un nuevo método enzimático para consolidar la celulosa del papel. Este método consiste en la síntesis de la celulosa con una enzima hidrolítica: la celulasa. Ésta actúa como una sintetasa, consolidando el papel cuando es mezclada en una solución orgánica de solvente/tampón (4:1) en presencia de un sustrato (β-cellobiosyl fluoride). Para mejorar el tratamiento añadimos un gel de agar-agar con todos los reactivos necesarios. Para observar el estado de las fibras antes y después del tratamiento, realizamos test mecánicos y fotografías de microscopía electrónica de barrido. Se observó que el proceso de consolidación casi consigue recuperar el estado físico inicial de las fibras así como su resistencia al desgarre y alargamiento.
