13. 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.

14. Resposta ao estresse Ãcido em leveduras da fermentaÃÃo alcÃolica industrial
Fuel-ethanol fermentation process includes a continuous recycle of the yeast biomass, with yeast cell being exposed to low pH values. It promotes acidic stress that leads to a decrease in cell viability. The aim of his work is to study the factors responsible for cell resistance to acid stress from the identification of yeast gene that are responsive to this

15. Evaluation of stress and of the fermentative potential of Saccharomyces isolates in the jaboticaba microvinification / AvaliaÃÃo de estresse e do potencial fermentativo de isolados de Saccharomyces na microvinificaÃÃo da jabuticaba.
Strains of Saccharomyces yeast are the main agents responsible for alcoholic fermentation. Those yeasts adapted to the conditions of the must (fermentative) or to be about to adapting (laboratory ones) can develop under a number of stressing challenges during vinification. The objectives of this work were to evaluate the behavior of thirteen isolates Sacchar

16. Participação da progesterona e do estradiol na redução das crises convulsivas induzida pela gestação em um modelo genético de epilepsia.
Pregnancy reduces the intensity of epileptic seizure in part of the population of a genetic model of reflex epilepsy in which seizures are induced by high intensity sound stimulation, the Wistar Audiogenic Rats (WAR), as it has been shown by previous studies of our lab. However, the mechanism involved in this reduction has not been yet clarified. Several stu

17. Efeito in vitro de Saccharomyces cerevisiae sobre Guignardia citricarpa, agente causal da pinta preta dos citros. / In vitro effect of Saccharomyces cerevisiae on Guignardia citricarpa, causal agent of citrus black spot.
Due to the consumers perception about the impact caused by pesticides utilization over the environment and human health, besides the acquisition of resistance for part of the phytopathogens, the society has exercised pressures that had led to the establishment of governmental politics that restrict the use of fungicides leading agriculturists and researchers

18. Efeitos da viabilidade da levedura e da contaminação bacteriana na fermentação alcoólica. / Effects of viability of yeast and bacterial contamination in alcoholic fementation saccharomyces cerevisiae.
The present study reports the evaluation of pour plate method in drops as an alternative to count the bacteria L. fermentum CCT 1407 in isolated culture, or in mixed culture with Saccharomyces cerevisiae, using the means of cultivation MRS and actidiona as inhibitor of yeast. The analysis of the results revealed that the pour plate method was equivalent to t

19. Avaliação da imunidade protetora de uma cepa atenuada de Eimeria acervulina, em galinhas (Gallus gallus), apos desafios com as cepas parentais homologa e duas heterologas
Evaluation of protective immunity produced by immunization of chickens (Gallus gallus) with the attenuated tine "Cu" of Eimeria acervulina after challenge with its homologous and two heterologous strains "PePa" e "I" was performed. Seven day old White Leghorn SPP (Specific Pathogen Pree) chickens were used for experiments. Each bird received a dose of lxl03

20. Comparison of mild and severe strains of papaya ringspot virus based on their coat protein. / Comparação de estirpes fracas e severas do papaya ringspot virus com base na capa protéica.
Papaya ringspot virus (PRSV), a species of the enus Potyvirus, is classified into two strains: "papaya" (P) and "watermelon" (W). Papaya ringspot virus - type W (PRSV-W) has been considered one of the most important viruses infecting cucurbits in Brazil due to its predominance and significative damage caused on the crops. The control of the disease caused by

21. Re-identificação e caracterização genética da levedura IZ-987 utilizando marcadores moleculares. / Re-identification and genetic characterization of IZ-987 yeast strain using molecular markers.
A identificação de leveduras por métodos moleculares e bioquímicos teve um grande impacto na sistemática e, devido aos resultados recentes este grupo sofreu alterações taxonômicas. A linhagem de levedura IZ-987 tem sido utilizada na fermentação de caldo de cana-de-açúcar para a obtenção de aguardente no Departamento de Agroindústria, Alimentos

22. A mutant CHO-K1 strain with resistance to Pseudomonas exotoxin A and alphaviruses fails to cleave Sindbis virus glycoprotein PE2.
RPE.40, a mutant CHO-K1 strain selected for resistance to Pseudomonas exotoxin A, is defective in the production of infectious alphaviruses, although viruses are taken in and processed normally (J. M. Moehring and T. J. Moehring, Infect. Immun. 41:998-1009, 1983). To determine the cause of this defect, the synthesis of Sindbis virus proteins was examined. RP

24. The amino-terminal residue of Sindbis virus glycoprotein E2 influences virus maturation, specific infectivity for BHK cells, and virulence in mice.
The E2 glycoprotein of Sindbis virus is synthesized as a precursor, PE2, which is cleaved by furin or a furin-like host cell protease at a late stage of maturation. The four-residue PE2 cleavage signal conforms to the basic amino acid-X-basic-basic motif which is present in many other viral and cellular glycoproteins which are processed by the cellular enzym
