1. Bioethanol strains of Saccharomyces cerevisiae characterised by microsatellite and stress resistance
Abstract Strains of Saccharomyces cerevisiae may display characteristics that are typical of rough-type colonies, made up of cells clustered in pseudohyphal structures and comprised of daughter buds that do not separate from the mother cell post-mitosis. These strains are known to occur frequently in fermentation tanks with significant lower ethanol yield wh

2. Dinâmica da Fermentação Alcóolica: Aplicação de Redes Booleanas na Dinâmica de Expressão Gênica em Linhagens de Saccharomyces Cerevisiae durante o Processo Fermentativo / Dynamics of alcoholic fermentation: application of Boolean networks in the dynamics of gene expression in Saccharomyces cerevisiae strains during fermentation process
Na busca por soluções que maximizem a produção de etanol, o melhoramento genético de diferentes linhagens de levedura tornou-se foco de investigação em diversos centros de pesquisa. Com o recente sequenciamento de uma linhagem selvagem utilizada nas usinas sucroalcooleiras brasileiras, a linhagem PE-2 da espécie Saccharomyces cerevisiae, surgiu o int

3. Fisiologia da fermentação alcoólica : análise da expressão gênica de uma linhagem industrial de Saccharomyces cerevisiae durante o processo fermentativo / Physiology of the alcoholic fermentation : gene expression analysis of a Saccharomyces cerevisiae industrial strain during the fermentation process
A fermentação alcoólica realizada por leveduras da espécie Saccharomyces cerevisiae é atualmente o principal processo em escala econômica para a produção de etanol a partir de fontes renováveis (bioetanol). Entretanto, as linhagens isoladas há quase duas décadas vêm perdendo gradualmente seu desempenho fermentativo ao longo dos anos, reduzindo o

4. The hydrophobicity and roughness of a nasoenteral tube surface influences the adhesion of a multi-drug resistant strain of Staphylococcus Aureus
In this study, we examined the physiochemical properties of nasoenteral feeding tubes made from two different types of polymer: silicone materials and polyurethane. The internal surfaces of the nasoenteral feeding tubes were analyzed for their hydrophobicity, roughness, microtopography, rupture-tension and ability to stretch. We also studied the adhesion of

5. Estudo da fermentação do hidrolisado de batata-doce utilizando diferentes linhagens de Saccharomyces cerevisiae
Ethanol is the most suitable substitute for oil-based fuels. The performance of the fermentation is affected by several factors, therefore the aim of this work was to evaluate the efficiency of the fermentation of a hydrolyzed must of sweet potato using three strains of the Saccharomyces cerevisiae. It was also evaluated the effect of three forms of the proc

6. Análise da variação cariotípica e dos mecanismos de recombinação em leveduras industriais (Saccharomyces cerevisiae) durante o processo de fermentação alcoólica / Analysis of the karyotypic variation and the recombination mechanisms industrial yeast (Saccharomyces cerevisiae) during the alcoholic fermentation process
Brazilian sugar cane ethanol stands out among the energetic alternatives available nowadays. In the fermentation process to produce ethanol it is used the yeast Saccharomyces cerevisiae. One of the most widely adopted strains is the industrial isolate PE-2, currently used by ~30% of Brazilian distilleries, generating ~10% of the worlds ethanol supply. This

7. Strain differences in baroceptor reflex in adult Wistar Kyoto rats
OBJECTIVES: A subset of normotensive Sprague-Dawley rats show lower baroreflex sensitivity; however, no previous study investigated whether there are differences in baroreflex sensitivity within this subset. Our study compared baroreflex sensitivity among conscious rats of this specific subtype. METHODS: Male Wistar Kyoto (WKY) rats (16 weeks old) were studi

8. DETERMINAÇÃO DAS DEFORMAÇÕES RESIDUAIS LONGITUDINAIS DECORRENTES DAS TENSÕES DE CRESCIMENTO EM Eucalyptus spp. / DETERMINATION OF LONGITUDINAL RESIDUAL DEFORMATION DUE TO THE STRESS OF GROWTH IN Eucalyptus spp.
O presente estudo foi desenvolvido com o objetivo de determinar as deformações residuais longitudinais (DRL), decorrentes das tensões de crescimento em árvores em pé e vivas de diferentes clones de Eucalyptus spp. Para tanto, foram selecionados 12 clones do gênero Eucalyptus com 9 anos de idade, por meio da área basal (G), sendo, estes, plantados em u

9. Bioaccumulation of aluminium and its effects on toxic alcoholic fermentation in industries strains of Saccharomyces cerevisiae / Bioacúmulo de alumínio e seus efeitos tóxicos na fermentação alcoólica em linhagens industriais de Saccharomyces cerevisiae
This study aimed to assess the effect of aluminium on the alcoholic fermentation using different strains of industrial yeasts (CAT-1, BG-1, PE-2, Fleischmann and wild yeast colonies isolated from production of alcohol fuel called C1, C5 , C6, C8, C10 and C11) in different concentrations of aluminium and also examine the accumulation of metal in yeast during

10. Antagonismo entre leveduras e bactérias láticas na fermentação alcoólica / Antagonism between yeasts and lactic acid bacteria in alcoholic fermentation
This study aimed to evaluate the antagonism between yeasts and contaminating bacteria of the ethanol production process with different metabolisms (homo- and heterofermentative) in different conditions. Thus, the fermentation performance of Saccharomyces cerevisiae strains used in industrial fermentation (BG-1, CAT-1, PE-2 and Fleischmann) was analyzed in co

11. Anti-flagellin antibody responses elicited in mice orally immunized with attenuated Salmonella enterica serovar Typhimurium vaccine strains
In the present study we investigated the flagellin-specific serum (IgG) and fecal (IgA) antibody responses elicited in BALB/c mice immunized with isogenic mutant derivatives of the attenuated Salmonella enterica serovar Typhimurium (S. Typhimurium) SL3261 strain expressing phase 1 (FliCi), phase 2 (FljB), or no endogenous flagellin. The data reported here in
