Abstract

LA PRESENTE INVENCION CONSISTE EN UN NUEVO MICROORGANISMO (AZOTOBACTER CHROOCOCCUM CEPA PHA, CECT 4435), OBTENIDO MEDIANTE MUTACION INDUCIDA CON N-METIL-N-NITRO-N-NITROSOGUANIDINA, CAPAZ DE ACUMULAR DURANTE SU CRECIMIENTO (SIN NINGUNA LIMITACION, NUTRICIONAL) POLI-HIDROXIALCANOATOS (PHAS). LA UTILIZACION DE ESTA BACTERIA EN PROCESOS FERMENTATIVOS, UTILIZANDO DIFERENTES FUENTES DE CARBONO (AZUCARES, ALPECHIN O ACIDOS ALCANOICOS), POSIBILITA LA PRODUCCION DE HOMOPOLIMEROS (POLI-3 HIDROXIBUTIRATO) O COPOLIMEROS (POLI-3 HIDROXIBUTIRATO/3 HIDROXIVALERATO), SIENDO LA RELACION MOLECULAR DE LOS COPOLIMEROS DEPENDIENTE DE LA RELACION NUTRICIONAL GLUCOSA/PROPIONICO Y GLUCOSA/VALERICO.THE PRESENT INVENTION CONSISTS OF A NEW MICROORGANISM (AZOTOBACTER CHROOCOCCUM CEPA PHA, CECT 4435), OBTAINED THROUGH N-METHYL-N-NITRO-N-NITROSOGUANIDINE, CAPABLE OF ACCUMULATING DURING ITS GROWTH. HYDROXIALCANOATES (PHAS). THE USE OF THIS BACTERIA IN FERMENTATIVE PROCESSES, USING DIFFERENT SOURCES OF CARBON (SUGARS, ALPECHIN OR ALCANOIC ACIDS), POSSIBILITIES THE PRODUCTION OF HOMOPOLIMEROS (POLI-3 HIDROXIBUTIRATO) OR COPOLIMEROSHARIUM (3 OF THE COPOLYMERS DEPENDENT ON THE NUTRITIONAL RELATION GLUCOSE / PROPIONEUM AND GLUCOSE / VALERICO.
