Abstract

PROCEDIMIENTO DE FERMENTACION PARA LA PRODUCCION DE CELULAS BACTERIANAS QUE ACUMULAN POLIHIDROXIALCANOATOS. LA INVENCION DESCRIBE UN PROCEDIMIENTO MICROBIOLOGICO DE FERMENTACION POR EL QUE SE OBTIENEN CELULAS CON UN ALTO CONTENIDO EN POLIHIDROXIBUTIRATO (PHB). EL PROCEDIMIENTO CONSISTE EN LA FERMENTACION AEROBIA DE HALOFERAX MEDITERRANEI SIN TENER QUE UTILIZAR MEDIDAS ESPECIALES DE ESTERILIDAD, CON EL CONSIGUIENTE AHORRO ECONOMICO EN SU PRODUCCION INDUSTRIAL. EL MEDIO DE CULTIVO CONTIENE UNA ALTA CONCENTRACION DE SALES MARINAS (25%), ADEMAS DE SALES DE AMONIO, HIERRO Y FOSFATOS. EL PH SE MANTIENE PROXIMO A LA NEUTRALIDAD Y LA TEMPERATURA ALREDEDOR DE 45GC. COMO FUENTE DE HIDRATOS DE CARBONO SE UTILIZA GLUCOSA. LA CANTIDAD DE AL MENOS UNO DE SUSBSTRATOS ESENCIALES ES LIMITADA, A FIN DE CONSEGUIR LA ACUMULACION DE PHB.FERMENTATION PROCEDURE FOR THE PRODUCTION OF BACTERIAL CELLS ACCUMULATING POLYHYDROXIALCANOATES. THE INVENTION DESCRIBES A MICROBIOLOGICAL FERMENTATION PROCEDURE BY WHICH CELLS WITH A HIGH CONTENT IN POLYHYDROXYBUTYRATE (PHB) ARE OBTAINED. THE PROCEDURE CONSISTS OF THE AEROBIC FERMENTATION OF HALOFERAX MEDITERRANEI WITHOUT HAVING TO USE SPECIAL STERILITY MEASURES, WITH THE CONSEQUENT ECONOMIC SAVINGS IN ITS INDUSTRIAL PRODUCTION. THE CULTIVATION MEDIA CONTAINS A HIGH CONCENTRATION OF MARINE SALTS (25%), IN ADDITION TO AMMONIUM, IRON AND PHOSPHATE SALTS. THE PH REMAINS NEAR NEUTRALITY AND TEMPERATURE AROUND 45GC. GLUCOSE IS USED AS A SOURCE OF CARBON HYDRATES. THE AMOUNT OF AT LEAST ONE OF ITS ESSENTIAL SUBSTRATES IS LIMITED IN ORDER TO ACHIEVE THE ACCUMULATION OF PHB.
