A RECOMBINANT VECTOR AND A TRANSFORMANT WITH AN IMPROVED PRODUCTIVITY OF BIO-ETHANOL

摘要

PURPOSE: A yeast transformant with improved bio-ethanol productivity is provided to use in SSF(simulateous saccharification and fermentation) or consolidated bioprocessing. CONSTITUTION: A recombinant vector, p-alpha-EgE-alpha-BG1 comprises a gene encoding Clostridium sp-derived endoglucanase and gene encoding Saccharomycopsis sp.-derived betaglucosidase. A transformant transformed by the recombinant vector, p-alpha-EgE-alpha-BG1. A bio-ethanol is produced by culturing transformed yeast under the presence of substrate. The substrate is starch or fiber.
