Saccharomyces cerevisiae.Ethanol is the most suitable substitute for oil-based fuels.The performance of the fermentation is affected by several factors, therefore the aim of this work was to evaluate the efficiency of the fermentation of a hydrolyzed must of sweet potato using three strains of the Saccharomyces cerevisiae.It was also evaluated the effect of three forms of the processes conduction in the fermentation yield, efficiency and viability of yeast at the end process.Among the parameters evaluated, only the cell viability showed significant difference.The strain PE-2 would be the most suitable for the fermentation of the hydrolysed sweet potato.
