This research addresses the application of compound polyethylene glycol (PEG) of molecular weight 1500, whose objective is to degrade the inhibiting compounds present during the enzymatic hydrolysis of Cavendish variety ripe banana peels. Likewise, three experiments were conducted on 60% ground banana peel, to which PEG was added at different concentrations: 0.01; 0.02; and 0.03 g/g biomass. The enzymatic hydrolysis was performed with conidia of the Trichoderma viride fungus and its subsequent alcoholic fermentation with commercial active dry yeast Saccharomyces cerevisiae, which was previously activated. The best result corresponds to the PEG3 experiment (0.03 g/g biomass), with which a greater increase of reducing sugars was obtained. In addition, significant differences were found (p<0.5) in the glucose obtained among the three hydrolytic treatments. The results show that bioethano...

Esta investigación aborda la aplicación de un compuesto de polietilenglicol (PEG) de masa molecular 1500, cuyo objetivo es degradar los compuestos inhibidores presentes durante la hidrólisis enzimática de la cáscara de banano maduro de la variedad Cavendish. Asimismo, se realizaron tres experimentos al 60% de cáscara de banano molida, en los que se adicionó PEG a diferentes concentraciones: 0,01; 0,02; 0,03 g/g biomasa. La hidrólisis enzimática se realizó con conidios del hongo Trichoderma viride y su posterior fermentación alcohólica fue con levadura activa seca comercial de Saccharomyces cerevisiae, que previamente fue activada. El mejor resultado corresponde al experimento PEG3 (0,03 g/g biomasa), con el que se obtuvo un mayor incremento de azúcares reductores. Además, se encontraron diferencias significativas (p<0,5) para la glucosa obtenida entre los tres tratamient...
