Abstract

SE DESCRIBE UN TIPO DE LEVADURAS CAPACES DE UNA MAS EFICAZ FERMENTACION DE AZUCARES, ASI COMO UN PROCESO PARA SU OBTENCION Y EL USO DE LAS LEVADURAS ASI OBTENIDAS. ESTAS LEVADURAS MUESTRAN ELEVADAS TASAS METABOLICAS QUE DAN COMO RESULTADO, P.E., UNA MAYOR PRODUCCION DE DIOXIDO DE CARBONO Y ETANOL EN MEDIOS QUE CONTENGAN AZUCARES, COMO P.E. MALTOSA, COMO FUENTE PRINCIPAL DE CARBONO Y ENERGIA. LA TASA DE FERMENTACION DE AZUCARES SE VE POTENCIADA POR LA INTRODUCCION EN LA LEVADURA DE UNA O MAS CADENAS DE DNA QUE INCLUYEN AL MENOS UN GEN CODIFICADOR DE UNA PROTEINA QUE PROMUEVA LA ABSORCION Y/O CONVERSION METABOLICA INICIAL DE SUSTRATO DE AZUCAR TRANSPORTADO.
