15. Integração do processo de cristalização de frutose por adição de antissolvente
Fructose (C6H12O6) is a monosaccharide with increasing industrial interest, and with some advantages over other sugars, facts that have motivated many studies about its production from its aqueous solution, by crystallization. Fructose crystallization occurs, in general, with the addition of ethanol as anti-solvent, aiming the reduction of its solubility and

16. Efeito do tratamento tÃrmico e do Ãcido salicÃlico na atividade de polifenoloxidase, peroxidase e fenilalanina amÃnia-liase, nas caracterÃsticas fÃsico-quÃmicas e na incidÃncia de patÃgenos em morangos durante o armazenamento / Effect of heat treatment and salicylic acid on polyphenoloxidase, peroxidase and phenylalanine ammonia-liase activity, physical-chemistry characteristics and incidence of pathogens in strawberries during storage
The strawberry is a fruit that is highly perishable and are very susceptible to physical damage and fungal attack. The use of fungicides has been the primary method for reducing post-harvest diseases. Accordingly, alternative methods free of chemicals must be used in post-harvest to maintain the quality and prolong the life reduce the incidence of fungi. The

17. 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

18. Optimizing dehydration of apples Malus Domestica with fructo-oligosaccharide incorporation
The objective of the present study was to study the effect of the variables of the osmotic dehydration process on sliced Fuji apples (Malus domestica) using a 2 x 3² factorial design. The variables studied in the apple slices were the pretreatment (blanching or acidification), the temperatures (30, 45 and 60ºC) and the FOS concentration (40%, 50% and 60% m

20. Modelos para a produção de eritropoietina recombinante humana in vivo e in vitro com vetores plasmideais em ovinos / Models for the production of human recombinant erythropoietin in vivo and in vitro with plasmidial vectors in ovine
Some post-translational modifications are necessary for the production of biopharmaceutical proteins, such as recombinant human erythropoietin (rhEPO), with a good specific action and a high biological activity. These modifications are obtained only by bioreactors based on eukaryotic cell as mammary cells. Bioreactors, in vivo or in vitro, with this kind of

23. Hidrólise do óleo da amêndoa da macaúba com lipase extracelular de "Colletotrichum gloesporioides" produzida por fermentação em substrato líquido
Extracellular lipase production by the filamentous fungi Colletotrichum gloesporioides was tested using two fermentation methods: in liquid substrate and in solid substrate. The liquid substrate fermentation yielded a larger production of lipase by this microorganism and was selected as the method for obtaining the extracellular lipase crude solution. Aliquo

24. Effect of denture cleansers on Candida species biofilms formed on the surface of differents materiais used in dentures base / Efeito de limpadores quimicos sobre biofilmes de Candida formados sobre a superficie de materiais para base de proteses removiveis
Candida denture biofilm is considered the the primary aetiological agent for the development of oral candidosis, which is the most common fungal oral infection in humans. Although, for patients with limited motor capacity, chemical cleansing with immersion in denture cleansers has been shown to be effective in controlling Candida biofilm accumulation, limite
