On the other hand, the most important aspect of bioethanol
fermentation is the ethanol yield, or more specifi-
cally the industrial yield [15]. The yield is dependent on
many factors, such as the fermentative capacity of the cell
population, the microbial activity, and the resistance of
those industrial cells to stress conditions, particularly those
of yeasts [15,16]. Since S. cerevisiae can produce a high
concentration of ethanol, it is commonly used in industrial
ethanol production
