The aim of this thesis was to make the production of bioethanol from lignocellulosic waste "peladilla" Asparagus offwinalis "asparagus" using Candida utilis var. .major CECT 1430. This proceeded to perform the pre-treatment of peladilla asparagus by chemical, physical and physicochemical methods. Subsequently, we proceeded to perform the extraction of Total Reducing Sugars "ART", determining a maximum concentration of 7 g / L with which the fermentation broth was established. Before starting the fermentation process, a bioreactor of 16 cm stirred tank with Rushton turbine and proceeded to the preparation of the inoculum from the Candida strain utilis var major CECT 1430. The culture medium was formulated was constructed from dilutions of total reducing sugars from 7.0 to 0.85 g / L. The bioprocess was carried out at 25 ° C, at pH 4.0 to 4.5 and for a time of 72 hours; After this time pr...
