Abstract

METODO DE PREPARACION DE POLISACARIDOS EXTRACELULARES POR FERMENTACION DE BACTERIAS. CONSISTE EN CULTIVAR KLESBSIELLA PLANTICOLA DSM 3092 EN UN MEDIO NUTRITIVO QUE CONTIENE COMO FUENTE DE CARBONO GLUCOSA Y PEPTONA, FUENTES DE NITROGENO Y SALES MINERALES, EN CONDICIONES AEROBIAS EN UN MARGEN DE PH COMPRENDIDO ENTRE 6 Y 7,5, A UNA TEMPERATURA PROXIMA A 30JC, DURANTE UNOS 3 DIAS; Y SEPARAR EL EXPOLISACARIDO MEDIANTE PRECIPITACION CON DISOLVENTES ORGANICOS POLARES MISCIBLES EN AGUA, TALES COMO ACETONA O ALCANOLES C1-3. ESTOS EXPOLISACARIDOS TIENEN APLICACIONES COMO AGENTES ESPESANTES EN MEZCLAS DE YESO Y ENLUCIDO Y EN PASTAS DE ESTAMPACION TEXTIL.
