1. 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 bioethano

2. Sugarcane straw as a feedstock for xylitol production by Candida guilliermondii FTI 20037
Abstract Sugarcane straw has become an available lignocellulosic biomass since the progressive introduction of the non-burning harvest in Brazil. Besides keeping this biomass in the field, it can be used as a feedstock in thermochemical or biochemical conversion processes. This makes feasible its incorporation in a biorefinery, whose economic profitability c

3. Aproveitamento das fraÃÃes hemicelulÃsica e celulÃsica dos resÃduos do processamento do girassol para produÃÃo de bioetanol / Utilization of hemicellulosic and cellulosic fractions of waste from sunflower processing for bioethanol production
The researches on second generation ethanol, produced by agroindustrial wastes, have demanded special attention as a possible solution that can contribute to energy sustainability. Such production is based on lignocellulosic fiber conversion (cellulose and hemicellulose), which generates fermentable sugars that are biotransformed in bioethanol after some spe

4. Pré-tratamento do bagaço de cana-de-açúcar com H2SO4 diluído em reator piloto aquecido por vapor direto / Pre-treatment of sugarcane bagasse with dilute H2SO4 in pilot reactor heated by direct steam
This study aimed to evaluate how certain pretreatment conditions of sugarcane bagasse with dilute H2SO4 influence the size distribution of sugarcane bagasse, the chemical composition of solids pretreated and hemicellulosic hydrolysate, as well the enzymatic digestibility of pretreated solids. For that, previously, a sample of in natura sugarcane bagasse was

5. Aproveitamento do bagaço de abacaxi (Ananas comosus L. Merril) para produção biotecnológica de xilitol / Improvement of pineapple bran (Ananas comosus L. Merril) for biotechnological production of xylitol
Pineapple bran from a juice agribusiness was collected and characterized by quantitative saccharification for the monomeric sugar contents, glucose (29.9%), xylose (27.63%), arabinose (5.48%), and lignin (15.1%), making up the fiber. Then it was used to obtain hemicellulosic hydrolyzate by dilute-acid hydrolysis. The condition of hydrolysis was determined by

6. Avaliação de técnicas de separação combinadas para a purificação de xilose visando a obtenção de bioprodutos / Evaluation of combined separation techniques for the xylose purification aiming a production of bioproducts
O presente trabalho teve como objetivo avaliar o uso combinado de processos de separação, visando a adequação do substrato rico em xilose (hidrolisado de bagaço de cana) para a obtenção de produtos por via fermentativa. Foram estudados processos como coagulação e precipitação seletiva de impurezas coloidais, separação com membranas de microfiltr

7. The influence of pH, temperature and hydrolyzate concentration on the removal of volatile and nonvolatile compounds from sugarcane bagasse hemicellulosic hydrolyzate treated with activated charcoal before or after vacuum evaporation
This paper analyzes the influence of pH, temperature and degree of hydrolyzate concentration on the removal of volatile and nonvolatile compounds from sugarcane bagasse hemicellulosic hydrolyzate treated with activated charcoal before or after the vacuum evaporation process. Furfural and 5-Hydroxymethylfurfural were almost totally removed in all the experime
