The document provides an overview of a project titled "Pre-treatment Photocatalytic for the Obtention of Cellulosic Alcohol from Luffa Cylindrical" by Bernay CIFUENTES VANEGAS and Laura Cristina PATAQUIVA CHAUTÁ from the University of La Sabana. The project aims to evaluate the effect of photocatalytic pre-treatment with ilmenite on the production of ethanol from Luffa cylindrical. The study involves determining the optimal conditions for pH, UV irradiation time, and ilmenite concentration to maximize the production of reducing sugars after acid hydrolysis. The results show that the optimal conditions are a pH of 7, 3 hours of UV irradiation, and 0.1 grams of ilmenite, achieving a sugar yield of 1,211 mg/ml. The fermentation with Saccharomyces cerevisiae resulted in an ethanol yield of 5.78%. The photocatalytic pre-treatment was effective in producing reducing sugars and ethanol. The document also includes a theoretical framework, methodology, and detailed experimental results, along with conclusions and recommendations.The document provides an overview of a project titled "Pre-treatment Photocatalytic for the Obtention of Cellulosic Alcohol from Luffa Cylindrical" by Bernay CIFUENTES VANEGAS and Laura Cristina PATAQUIVA CHAUTÁ from the University of La Sabana.
