Abstract

LA PRESENTE INVENCION COMPRENDE UN CULTIVO PURAMENTE BIOLOGICO DE UN MICROORGANISMO PRODUCIENDO CELULOSA, PREFERIBLEMENTE UN PROTOFITO,Y METODO PARA SELECCIONARLO. LOS MICROORGANISMOS PRODUCTORES DE CELULOSAM SON CAPACES, DURANTE LA FERMENTACION EN UN MEDIO NUTRIENTE ACUOSO CONTENIENDO FUENTES ASIMILABLES DE CARBONO, NITROGENO Y SUBSTANCIAS INORGANICAS, DE INVERTIR LA DIRECCION DE EXTRUSION DE LAS FIBRAS DE CELULOSA. ESTA INVERSION DE LA DIRECCION DE LA EXTRUSION DE LAS FIBRAS DE CELULOSA SE EFECTUA SOBRE LA UNION DE MICROORGANISMOS PRODUCTORES DE CELULOSA, AL MENOS PERIODICAMENTE, PRIMERO EN UNA DIRECCION Y DESPUES EN OTRA DIRECCION A LO LARGO DE LA LONGITUD DE UNA TIRA DE CELULOSA DEPOSITADA EN PRINCIPIO PARA AÑADIR A ELLA OTRAS FIBRAS DE CELULOSA Y PRODUCIR UN TIRA LIADA DE CELULOSA TENIENDO UNA ANCHURA DE AL MENOS DOS FIBRAS DE CELULOSA ANTIPARALELAS. LOS MICROORGANISMOS PRODUCTORES DE CELULOSA DE LA PRESENTE INVENCION PUEDEN SER DE LOS GENEROS ACETOBACTERIUM, AGROBACTERIUM, RHIZOBIUM,PSEUDOMONAS O ALCALIGENAS, PREFERIBLEMENTE DEL GENERO ACETOBACTER. LA FAMILIA XYLINUM ACETOBACTER NQ5,ATCC 53582, ES LA FAMILIA MAS PREFERIDA. LA PRESENTE INVENCION COMPRENDE UN METODO PARA OBTENER CELULOSA MICROBIANA TENIENDO TENSION ESTRUCTURAL SUPERIOR Y SIENDO UN POLIMORFO APARENTE DE CELULOSA I Y CELULOSA II. LAS FIBRAS RETORCIDAS DE CELULOSA OBTENIDAS COMPRENDEN MULTIPLES FIBRAS DE CELULOSA TENIENDO UNA FORTALEZA SUPERIOR QUE LA CORRESPONDIENTE A LAS FIBRAS DE CELULOSA INDIVIDUALES DISPERSADAS ALEATORIAMENTE.
