Abstract
Procedimiento de preparación de composiciones enzimáticas para la isomerización de la glucosa en levulosa, que comprenden plaquetas o filamentos de éster de celulosa en las que se incluyen celulosas de un microorganismo que contiene glucosa-isomerasa capaz de isomerizar la glucosa en levulosa, caracterizado porque para su realización se separan las células de los microorganismos del substrato a expensas del cual se han desarrollado, se desea el caldo obtenido hasta un contenido en materia seca del 20 a 95% se mezcla el caldo deseado con un 5 al 100% en relación con el peso de las células, de una carga que comprende un compuesto magnésico poco soluble y eventualmente un compuesto de cobalto poco soluble; a la composición resultante se añade el éster celulósico, a razón del 25 a 100%, del peso de las células en forma de sol de 5 a 20%, en un disolvente miscible en agua adicionándose una cantidad de disolvente igual a 1 - 10 veces el peso de las células secas y una cantidad de agua tal que lacomposición final contenga una proporción de agua que represente 0,6 a 8 veces el peso del éster de celulosa, siendo la relación penderla final agua/disolvente inferior a 0,2, se da forma a la mezcla obtenida y se seca eventualmente.
