Abstract

PARA ELABORAR UNA SOLUCION DE ENCIMAS ECONOMICA Y RICA EN XILANO, QUE CONTENGA EN LA MENOR MEDIDA POSIBLE CELULOSA, SE PLANTEA CULTIVAR CONOCIDOS MICROORGANISMOS QUE PRODUZCAN XILANO EN CUBOS DE DESECHO DE METODOS VISCOSOS EN AGUAS RESIDUALES, Y SE PRESENTAN EN UNA CHAPA CELULOSA DE FIBRA ARTIFICIAL, CON EXTRACION ALCALINA, LA CUAL PUEDE SER APOYADA A TRAVES DE OXIGENO Y/O HIDROGENO PEROXIDO. ES APROPIADO ESTERILIZAR ANTES EL CUBO DE DESECHO, ASI COMO NEUTRALIZAR LAS AGUAS RESIDUALES Y ALTERAR CON NITROGENO COMO FUENTE DE ORIGEN, COMO POR EJEMPLO PEPTON, ACLARADOR DE LAVADO Y/O UREA. EL CULTIVO SE PUEDE CONSEGUIR CON TRONCOS DE TRIPODERMAS, ASPERGILO O SIZOFILO. DURANTE EL CULTIVO NACE LA SOLUCION DE ENCIMAS DESEADA, QUE PUEDE AISLARSE A TRAVES DEL AISLAMIENTO DE BIOMASA.
