Abstract

The present study aims to valorize the Typha australis stems, through second-generation bioethanol production using enzymatic hydrolysis and fermentation. The monitoring of fermentation kinetics parameters, such as pH, density, length of fermentation, and the Brix, indicated a great variability of these parameters during the fermentation process of the must with three Saccharomyces cerevisiae strains, such as Angel brand Thermal-tolerant alcohol active dry yeast, Angel brand super alcohol active dry yeast and Angel super alcohol active dry yeast in the presence of urea (CON2H4) used as a growth factor. The distillation of musts after fermentation has yielded ethanol extraction rate (% v / v at 20 ° C) between 4.95and 44.93 after fractional distillation. The best performance in ethanolic bioconversion was recorded with Angel brand super alcohol active dry yeast. This Saccharomyces cerevisiae strains could be used as effective ferments, in perspective of intensive production of second-generation bioethanol with Typha australis stems.
