FERMENTAÇÃO ALCOÓLICA DE HIDROLISADO HEMICELULÓSICO DE TORTA DE GIRASSOL POR Galactomyces geotrichum UFVJM-R10 E Candida akabanensis UFVJM-R131

The use of the hemicellulosic fraction of plants for the production of second generation bioethanol depends on microorganisms capable to ferment pentoses. Two yeast strains habile to xylose fermenting in synthetic medium, Candida akabanensis UFVJM-R131 and Galactomyces geotrichum UFVJM-R10, not yet registered in the literature for the production of bioethanol, were evaluated here in the alcoholic fermentation of the hemicellulosic hydrolyzate from sunflower cake. The biomass hydrolysis was performed by 38 minutes at 120 °C / 1 atm with 6% H2SO4 solution and solid / liquid ratio of 1:3.2. Chro...
