37. ObtenÃÃo de oligosscarÃdeos prebiÃticos por processo fermentativo a partir do suco de caju clarificado in natura / Obtentioin of prebiotic oligosaccharides for fermentative process from the clarificado cashew juice in natura
OligossacarÃdeos prebiÃticos sÃo carboidratos capazes de chegar ao intestino grosso onde sÃo metabolizados pelas bidifidobactÃrias e lactobacilos ali presentes estimulando o seu crescimento. A importÃncia destes microrganismos està associada a sua relaÃÃo com a melhoria da intolerÃncia à lactose, melhora da funÃÃo intestinal, melhoria do sistema

38. Avaliação da produção de toxina tetânica por "Clostridium tetani" cultivado por processos fermentativos descontínuo e descontínuo alimentado / Evaluation of the tetanus toxin for "Clostridium tetani" cultivated by batch fermentative and fed-batch process
The tetanus toxin is a neurotoxin synthesized by the bacillus Clostridium tetani that, after detoxification with formaldehyde, still exhibits antigenic and immunologic properties, hence its denomination of tetanus toxoid. Such a neurotoxin is produced by cultivations of the microorganism in vegetative form on a relatively complex specific medium containing g

39. Modeling and control of the acrylic acid synthesis by fermentative process / Modelagem e controle da sintese do acido acrilico via processo fermentativo
A síntese de ácido acrílico via processo fermentativo é um assunto recente, com poucas informações disponíveis na literatura e, tem despertado cada vez mais interesse de pesquisadores. Através da modelagem matemática, é possível obter uma melhor compreensão de um processo em sua totalidade, através de analogias abstratas que possibilitam a predi

40. Avaliação e desenvolvimento de algoritmos de controle aplicado a um processo extrativo de fermentação alcoolica continua / Development and evaluating the performance of predictive and adaptative controllers applied to an extractive fermentative process
0 objetivo deste trabalho foi desenvolver e avaliar diferentes algoritmos de controle para o processo extrativo de fermentação alcoólica contínua. Para isto foram comparados controladores do tipo preditivo e adaptativo. Para o controle preditivo, foi avaliado o Controle por Matriz Dinâmica (DMC) e foi desenvolvido um algoritmo de controle preditivo base

41. Processo biotecnolÃgico para conversÃo de algaroba (Prosopis juliflora (SW) D.C.) em etanol
In order to reduce the impact caused by gases in the greenhouse effect it is becoming necessary the utilization of biomass derivatives as alternative biofuels originated from renewable substrates. Mesquite [Prosopis juliflora (Sw.) D.C.] is a tropical arboreous leguminous plant fairly common in the semi-arid region of Brazil that thrives well in dry environm

42. Viabilidade da utilização de aditivos na ensilagem de capim-braquiarão (Brachiaria brizantha (Hochst ex A. Rich.) Stapf cv. Marandu), manejado sob intensidades de pastejo / Viability on the addictives utilization in braquiarão grass [Brachiaria brizantha (Hochst ex A. Rich.) cv. Marandu] silage process, managed under grazing intensities
Silage is a grassing food conserved by a fermentative process specialy used during scarcity period (dry season). It aims to conserve a high nutritional value with a minimum of losses. In order to assure its produced forage utilization efficiency, it needs to considerate its harvest by animals and machines in a system that uses rotational stocking method. In

43. Isolation, characterization and fermentative activity of mango pulp spoilage bacteria / Isolamento, caracterização e atividade fermentativa de bactérias deterioradoras de polpa de manga
The mango (Mangifera indica Linn.) is one of the most important tropical fruits. It is very appreciated due to its flavor and nutritional characteristics. The fruits are easily spoiled because of intrinsic factors, which makes difficult its commercialization in natura. An alternative to reduce the losts is the conservation of the mango as pulp, juice and nec

44. Sugar metabolization of Saccharomyces cerevisiae with transporter of sucrose and different invertase activity / Metabolização de açúcares em linhagens de Saccharomyces cerevisiae com e sem transportador de sacarose e diferentes atividades de invertase
The aim of this work was to evaluate the metabolic profile in the utilization of sugars, using different yeast strains (BG-1, CAT-1, FLEISHMANN, PE-2, 1403-7A and LCM001) with different growth medium and also to analyze behavior and the invertase activities of these yeast strains during fermentative process with recycling, similar to the industrial process.

46. Produção de Goma xantana empregando caldo de cana por xanthomonas campestris pv campestris NRRL B-1459
The development of the work plan proposed for this dissertation refers to the production of xanthan gum from sugarcane juice using the bacterium Xanthomonas campestris pv. campestris NRRL B-1459. Tests were conducted in 500 mL erlenmeyers flasks and in a 2.0-L reactor, in sucrose concentration range from 15 to 40 g/L, judiciously following the pre-establishe

48. Biotyping of industrial yeasts by the Killer system. / Biotipagem de leveduras industriais através do sistema Killer.
Agriculture is an important sector in the economy of Brazil. The sugar cane occupies 9% of the cultivated area in this country. The most important products from the sugar cane industry are sugar and alcohol, the latest produced by fermentative process by yeasts. During the fermentation the yeast population changes due to the interferences coming from the sug
