Abstract


The process of ethanol production in Brazil uses sucrose as thesugar cane juice or molasses as a substrate for Saccharomyces cerevisiae whichresults in high production of ethanol. This study aims to evaluate thebiotechnological potential of strains of Saccharomyces cerevisiae used insugarcane mills in the southern region of Mato Grosso do Sul, the main power strain used in the region are: Catanduva 1, Pedra 2, Barra Grande 1and Fleischmann. Microbiological analysis showed similarities betweenaspects analyzed in the strains. The strains that showed the bestfermentation performance was Catanduva 1, strain Pedra 2 and Barra Grande1 showed the same response and the lower fermentation was showed inthe lineage Fleischmann. This study presented that the characterization ofthe potential of yeast strains in the fermentation process can increase ethanolproduction.
