| Resumo: | The chemical or enzymatic hydrolysis of sugarcane bagasse, allows the obtaining of fermentable sugars used in the biotechnological production of ethanol by using commercial or native yeasts obtained from different lignocellulosic materials. The purpose of this study was to assess the production capacity of ethanol from a native yeast strain isolated in YPD and hydrolyzed sugar cane bagasse concentrated up to 75 %. Using as study variables the type of strain and processing time, a multivariate analysis (ANOVA) was performed for its evaluation. The results achieved with the selected strain UAT-3, were 0.441 7 g/g for YP/S and 0.076 7 g/L·h to 120 h for QP. The process conditions used in the present study allowed to isolate and select native strains of Sacharomyces cereviseae, with characteristics suitable to be used in industrial biotechnological proceses of ethanol production, using as substrate residues or by-products derived from the sugar industry such as bagasse of sugar. |
