1. Produção de celulases, purificação e caracterização bioquímico-cinética da β-galactosidase produzida por fungo isolado da região amazônica / Production of cellulases, purification and characterization of kinetic biochemical ß-galactosidase produced by fungus isolated from the Amazon.
The selection of cellulase-producing fungi is one of the possible estrategies for obtaining necessary enzymes to hydrolyze the lignocellulosic material of plant biomass and thereby contribute to the viability of cellulosic ethanol production. The aim of this study was achive a screening of isolated fungi from the Amazon region to assess the production of enz

2. Production of α-amylase from Streptomyces sp. SLBA-08 strain using agro-industrial by-products
Approximately 1.5 trillion tons are the estimated yearly biomass production, making it an essentially unlimited source of raw material for environmentally friendly and biocompatible products transformed by microorganism, specially fungi and actinomycetes. Several lignocellulosic residues, such as sisal waste and sugarcane bagasse contain starch in their stru

3. Construção de linhagens de Saccharomyces cerevisiae recombinantes superexpressoras de transportadores de pentoses. / Construction of Saccharomyces cerevisiae recombinant strains overexpressing pentoses transporters.
A conversão da biomassa para produção de etanol celulósico só é viável se a fração hemicelulósica e celulósica for utilizada no processo industrial. Para obtenção de leveduras capazes de produzir etanol a partir de pentoses, a captação desses açúcares é muito estudada, sendo que diversos autores concluíram que a interiorização do substra

4. Estudo da influência de pré-tratamentos de dois resíduos lignocelulósicos (bagaço do pedúnculo de caju e casca de coco) utilizados como substrato na indução à síntese de enzimas celulolíticas
Nowadays generation ethanol second, that t is obtained from fermentation of sugars of hydrolyses of cellulose, is gaining attention worldwide as a viable alternative to petroleum mainly for being a renewable resource. The increase of first generation ethanol production i.e. that obtained from sugar-cane molasses could lead to a reduction of lands sustainable

5. Fungos microaerobios na bioconversão de material lignocelulosico
Cellulose accounts for the major part of lignocellulose found in nature, and consequently, its degradation is essential for the operation of the global carbon cycle. Lignocellulose, such as wood, is mainly composed of a mixture of cellulose (40%), hemicellulose (20-30%), and lignin (15-30%). An association of enzymes acting in a concerted fashion degrades ce

6. IMMOBILIZED Saccharomyces cerevisiae AND Leuconostoc oenus FOR ALCOHOLIC AND MALOLACTIC FERMENTATION IN CONTINUOUS WINE MAKING
The use of sugarcane stalks to immobilize microorganisms by adsorption in continuous fermentation was investigated. The canes were peeled and cut horizontally and transversally into pieces 2 × 1 × 1 cm3. Scanning electron microscopy (SEM) was employed to verify the external and internal structure of the sugarcane stalk support prior to cell immobilization.

7. Effect of manganese on preferential degradation of lignin by Pleurotus ostreatus during solid-state fermentation.
Practical utilization of the polysaccharides in the lignocellulosic complex is limited because of the high lignin content of the complex. In this study we focused on the effect of Mn on lignin and cellulose biodegradation during solid-state fermentation by the edible mushroom Pleurotus ostreatus. Preferential degradation of lignin was enhanced by the additio
