“…A decrease of 100% was verified in the concentration of acetic acid in the sugarcane bagasse hemicellulosic hydrolysate after treatment with resins in the following order: MN-150, A-860, C-155, and A-103 (MARTÍNEZ et al, 2007). According to Villarreal et al (2006), acetic acid was totally or almost totally removed during treatment of eucalyptus hemicellulosic hydrolysate with ionexchange resins in the following sequence: cationic Applexion, anionic Purolite A-860, cationic Purolite C-150, and anionic Applexion. Meanwhile, the concentration of this acid was not largely affected (0-32%) by treatment with activated charcoal.…”

“…Rice bran extract has been used as a source of nutrients in the bioconversion of the xylose contained in different hemicellulosic hydrolysates into xylitol (MARTÍNEZ et al, 2002(MARTÍNEZ et al, , 2003(MARTÍNEZ et al, , 2007CANILHA;ALMEIDA E SILVA;SOLENZAL;MUSSATTO, ROBERTO, 2004;VILLARREAL et al, 2006;CANILHA et al, 2008). Rice bran is a by-product of the rice milling processing and is a source of vitamins and amino acids containing 12-15% oils, 11-12% proteins and 2.750 kcal.kg -1 of metabolizable energy (BUTOLO, 2002).…”

Xylose-to-xylitol bioconversion using 2.5 or 10% (v/v) rice bran extract was performed to verify the influence of this source of nutrients on Candida guilliermondii metabolism. Semisynthetic medium (SM) and sugarcane bagasse hemicellulosic hydrolysate detoxified with ion-exchange resins (HIE) or with alteration in pH combined with adsorption onto activated charcoal (HAC) were fermented in 125 mL Erlenmeyer flasks at 30 ºC and 200 rpm for 72 hours. Activated charcoal supplemented with 2.5% (v/v) rice bran extract was fermented by C. guilliermondii in a MULTIGEN stirred tank reactor using pH 5.0 and 22.9/hour oxygen transfer volumetric coefficient. Higher values of xylitol productivity (0.70, 0.71, and 0.62 g.Lh-1) and xylose-to-xylitol conversion yield (0.71, 0.69, and 0.63 g.g-1) were obtained with 2.5% (v/v) rice bran in semisynthetic medium, ion-exchange resins, and activated charcoal, respectively. Moreover, during batch fermentation, the xylitol volumetric productivity and fermentation efficiency values obtained were 0.53 g.Lh-1 and 61.1%, respectively.

“…The inhibitors concentrations (acetic acid 3.56 g L -1 , furfural 0.03 g L -1 , HMF 0.03 g L -1 and total phenols 0.89 g L -1 ) are within or under the range of values usually found in other sources of hemicellulosic hydrolysates, in general, 1-3.41 g L -1 of acetic acid, 0.04-0.26 g L -1 of furfural, 0.008-1.56 g L -1 of HMF and 2.12-2.23 g L -1 of total phenols (Mussatto & Roberto, 2004;Canilha et al, 2005;Marton et al, 2006;Villarreal et al, 2006;Sene et al, 2011).…”

A B S T R A C TSunflower is among the major oil seeds crop grown in the world and the by-products generated during the seeds processing represent an attractive source of lignocellulosic biomass for bioprocesses. The conversion of lignocellulosic fibers into fermentable sugars has been considered as a promising alternative to increase the demand for ethanol. The present study aimed to establish the fermentation conditions for ethanol production by Scheffersomyces stipitis ATCC 58376 in sunflower meal hemicellulosic hydrolysate, through a 2 3 CCRD (Central Composite Rotational Design) factorial design. Under the selected conditions (pH 5.25, 29 ºC and 198 rpm) the final ethanol concentration was 13.92 g L -1 and the ethanol yield was 0.49 g g -1 .Valorização do farelo de girassol através da produção de etanol a partir da fração hemicelulósica R E S U M O O girassol está entre as principais oleaginosas cultivadas no mundo e os subprodutos gerados durante o processamento das sementes representam uma fonte atraente de biomassa lignocelulósica para bioprocessos. A conversão de fibras lignocelulósicas em açúcares fermentáveis tem sido considerada uma alternativa promissora para aumentar a demanda de etanol. O presente estudo teve, como objetivo, estabelecer as condições de fermentação para a produção de etanol por Scheffersomyces stipitis ATCC 58376 em hidrolisado hemicelulósico de farelo de girassol através de um planejamento fatorial DCCR 2 3 . Sob as condições selecionadas (pH 5,25, 29 ºC e 198 rpm) a concentração final de etanol foi 13,92 g L -1 e o rendimento 0,49 g g -1 .
