Abstract

UN METODO PARA PRODUCIR ETANOL POR FERMENTACION, EN EL QUE SE FERMENTA UN HIDROLIZADO DE ALMIDON, EN UN MEDIO DE FERMENTACION UNICO, UTILIZANDO UNA CEPA DE ZYMOMONAS MOBILIS. PREFERIBLEMENTE, LA FERMENTACION COMPRENDE SACARIFICAR EL ALMIDON PARA FORMAR GLUCOSA POR ACCION DE AMILOGLUCOSIDASA Y PRODUCIR ETANOL A PARTIR DE LA GLUCOSA POR ACCION DE DICHA CEPA, AÑADIDA AL MEDIO DE FERMENTACION DESPUES DE LA SACARIFICACION, MANTENIENDOSE EL PH DEL MEDIO DE FERMENTACION ENTRE 3,5-7,0 Y LA TEMPERATURA DEL FERMENTADOR ENTRE 25-40JC. EL ALMIDON SE DERIVA DE CEREALES O RAICES Y EL MEDIO DE FERMENTACION INCLUYE PEPTONA, EXTRACTO DE LEVADURA, DIHIDROGENOFOSFATO POTASICO, AMONICO O SODICO, SULFATO O HIDROXIDO AMONICO, UREA, SULFATO MAGNESICO, FOSFATO DIAMONICO Y OTROS, ASI COMO SUS MEZCLAS. EL ETANOL OBTENIDO ES COMERCIALMENTE UTIL COMO COMPONENTE DE LA GASOLINA O COMO PRODUCTO DE BASE PARA FABRICAR ETILENO.
