چکیده

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 23. 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.

In situ Evaluation of Ruminal Degradability and Intestinal Digestibility of Sunflower Meal Compared to Soybean Meal

The aim of this study was to compare the nutritional value of sunflower meal (SFM) and soybean meal (SBM) protein by determining both its ruminal degradability and intestinal digestibility. Three non lactating Jersey cows fitted with a rumen and T-type duodenal cannulas were used to estimate rumen degradability and intestinal digestibility of SFM and SBM dry matter (DM) and crude protein (CP). ...
