Abstract

PROCEDIMIENTO PARA LA PREPARACION DE PELICULAS DE CELULOSA. COMPRENDE LAS SIGUIENTES ETAPAS: PREPARAR UNA MEDIO DE CULTIVO UTILIZANDO COMO NUTRIENTES UNA FUENTE DE NITROGENO Y DE HIDRATOS DE CARBONO (POR EJEMPLO TEA SINENSIS Y SACAROSA); SEMBRAR EN ESTE MEDIO UN CULTIVO DE ACETOBACTER ESPECIE XYLINUM; INCUBAR EL CULTIVO A TEMPERATURAS QUE PERMITAN LA ACTIVIDAD DE LA BACTERIA (UNOS 28JC) DURANTE UN ESPACIO DE TIEMPO ADECUADO PARA LA FORMACION DE LA PELICULA (DE 26 A 96 HORAS); RETIRAR LA PELICULA FORMADA DEL MEDIO Y SECARLA EN ESTADO DISTENDIDO, REPONIENDO LOS NUTRIENTES GASTADOS DEL MEDIO DE CULTIVO PARA REINICIAR EL PROCEDIMIENTO. APLICABLES COMO SUSTITUTIVOS SINTETICOS DE LA PIEL EN EL TRATAMIENTO DE QUEMADURAS.
