Valorization of Typha Australis Stems in Bioethanol Production Using Enzymatic Hydrolysis and Biofermentation

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.

Assessment of biofuel potential of the red variety of cashew apple

“…The nutrient supply therefore has a significant influence on the fermentation kinetics, especially at the level of S3. These results were more in line with the indications in the literature on the nutritional requirements of the yeast Saccharomyces cerevisiae [30] . At the level of all the physicochemical parameters followed, in the presence of the growth factor, a much more rapid evolution was observed.…”

“…The presence of nutrients for yeasts in a culture medium has a proven positive influence on ethanol production [13] . Some researchers have also shown that the presence in a fermentation broth of extracts of yeast, urea, ammonium ions [30] , calcium and magnesium [31] , has effects protectors on both cell growth and viability. It also promotes an acceleration of fermentation speed and ethanol production [32] .…”

Experimental Investigation of Thermal and Mechanical Properties of Clay Reinforced with Typha australis: Influence of Length and Percentage of Fibers

“…In Benin, the proliferation of this plant is a real problem for the rivers in the valley. This plant has been valorized into bioethanol produced by enzymatic hydrolysis and bio-fermentation, which can be used as a biofuel substitute for gasoline, reducing CO 2 by 90% [22]. A limited number of researchers have studied the hydric, thermal and mechanical characterization of Typha australis using clay or cement as a binder.…”
