Abstract
PROCEDIMIENTO PARA EL AISLAMIENTO DE POLISACARIDOS MICROBIANOS.CONSISTE EN MEZCLAR LAS SOLUCIONES ACUOSAS DE LOS POLISACARIDOS EN UN MARGEN DEL PH COMPRENDIDO ENTRE 2 Y 6,5, CON UNA AMINA DE FORMULA: NRRR, EN LA QUE R SIGNIFICA ALCOHILO CON 10 A 20 ATOMOS DE CARBONO; Y R Y R, QUE SON IGUALES O DIFERENTES, SIGNIFICAN METILO O ETILO. EL ADUCTO PRECIPITADO FORMADO A PARTIR DEL POLISACARIDO MICROBIANO Y LA AMINA, SE SEPARA DE DICHA SOLUCION ACUOSA.EL ADUCTO PRECIPITADO SE UTILIZA COMO AGENTE ESPESANTE, GELIFICANTE, SUSPENDEDOR, COLOIDE PROTECTOR O COMO AGENTE FIJADOR DE AGUA.
