Neste trabalho foi utilizado o res?duo agroindustrial do processo de beneficiamento do ?leo do dend? (Elaeis guineensis) para obten??o de um hidrolisado ?cido hemicelul?sico para posterior fermenta??o. O hidrolisado foi obtido atrav?s da utiliza??o de ?cido sulf?rico dilu?do o qual se mostrou eficiente na solubiliza??o da hemicelulose. Tr?s m?todos de destoxifica??o dos inibidores foram testados dentre os quais se destacaram os tratamentos por carv?o ativado e a combina??o do tratamento empregando overliming e carv?o ativado, com remo??o de compostos fen?licos, furfural e 5-hidroximetilfurfural acima de 90% do hidrolisado. As linhagens de Scheffersomyces stipitis NRRLY 1214 e NRRLY 7124 apresentaram os maiores valores de etanol, com valores correspondentes de 6,2 e 6,13 g L-1, no meio destoxificado por overliming com suplementa??o. Estas linhagens, neste mesmo meio, alcan?aram as maiores taxas de Yp/s (0,32 e 0,33) e Ef (64,46 e 64,89%). Os dados obtidos corroboram que as linhagens estudadas apresentam potencial para a fermenta??o da fra??o hemicelul?sica da torta de dend?. O uso de meio de hidrolisado ?cido da torta de dend?, sem suplementa??o, se mostra invi?vel nas condi??es testadas, pois reflete em valores insignificantes de etanol. Os dados obtidos contribuir?o de forma positiva no aproveitamento de res?duos agroindustriais, bem como para os avan?os na ?rea de obten??o de etanol de segunda gera??o.Submitted by Jos?

Pesquisa do Estado de Minas Gerais (FAPEMIG)Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico (CNPq)Disserta??o (Mestrado) ? Programa de P?s-gradua??o em Biocombust?veis, Universidade Federal dos Vales do Jequitinhonha e Mucuri, [2016].In recent decades, the study of strategies that provide better yields in ethanol from lignocellulosic biomass has intensified. In this study we used the agroindustrial residue from the palm oil milling process (Elaeis guineensis) to obtain an acid-hydrolyzed hemicellulose for fermentation. The hydrolyzate was obtained using dilute sulfuric acid, which was efficient at dissolving the hemicellulose. Three methods of detoxification of inhibitors were tested, including the use of activated carbon treatment and a combination treatment employing overliming and activated carbon. Greater than 90% of the phenolic substances, furfural and 5-hydroxymethylfurfural were removed from the hydrolysis product. The NRRLY 1214 and NRRLY7124 strains of Scheffersomyces stipitis produced the highest yields of ethanol, 6.2 and 6.13 g L-1, in the medium detoxified by the overliming procedure. These strains achieved the highest rates of Yp / s (0.32 and 0.33) and Ef (64.46 and 64.89%) in the same medium. The data confirm that these strains have a potential for fermentation of the hemicellulose fraction of palm kernel cake. The use of the acid hydrolyzate of palm kernel cake without supplementation was shown to be unfeasible under the conditions tested, as reflected in the insignificant yields of ethanol. The data obtained will contribute positively to the use of agro-industrial waste, as well as to advances in the area of the production of second-generation ethanol.porUFVJMA concess?o da licen?a deste item refere-se ao ? termo de autoriza??o impresso assinado pelo autor, assim como na licen?a Creative Commons, com as seguintes condi??es: Na qualidade de titular dos direitos de autor da publica??o, autorizo a Universidade Federal dos Vales do Jequitinhonha e Mucuri e o IBICT a disponibilizar por meio de seus reposit?rios, sem ressarcimento dos direitos autorais, de acordo com a Lei n? 9610/98, o texto integral da obra disponibilizada, conforme permiss?es assinaladas, para fins de leitura, impress?o e/ou download, a t?tulo de divulga??o da produ??o cient?fica brasileira, e preserva??o, a partir desta data.info:eu-repo/semantics/openAccessFermenta??o do hidrolisado ?cido hemicelul?sico da torta de dend?
