1. Influence of summer crop residues on 15N present in organic matter fractions under two lowland soils
RESUMO: O Rio Grande do Sul possui cerca de 20% da área total de solos de terras baixas, propícias para o cultivo do arroz (Oryza sativa) irrigado por inundação. Buscando mitigar danos ocasionados com o monocultivo de arroz, novas culturas, como o sorgo (Sorghum bicolor) e a soja (Glycine max), têm sido cultivadas nestas áreas. Com diferentes qualidad

2. Effects of in ovo injection of lysine and methionine into fertile broiler (parent stock) eggs on hatchability, growth performance, caecum microbiota, and ileum histomorphology
ABSTRACT We investigated the effect of in ovo injection of lysine, methionine, or their mixture into fertile broiler eggs on hatchability, chick weight, growth performance, inner organ development, caecum total aerobic bacteria, E. coli, coliforms, Enterobactericaea, and ileal histomorphology of broilers. Three hundred fertile eggs obtained from 60-week-old

3. Evaluation of a Probiotic and a Competitive Exclusion Product Inoculated In Ovo on Broiler Chickens Challenged with Salmonella Heidelberg
ABSTRACT The present study evaluated a probiotic and a competitive exclusion product injected in ovo on day 18 of incubation together with Marek's disease vaccine in eggs of 56-week-old broiler breeders. Three experiments were carried out. The first trial evaluated the effect of treatments on hatchability, cecal colonization of Salmonella Heidelberg (SH), an

4. Characterization of a thermostable endoglucanase produced by Isoptericola variabilis sp. IDAH9
Abstract This study aimed to isolate and evaluate the cellulase activity of cellulolytic bacteria in hot springs of Dehloran, Ilam province, Iran. Water and sludge samples were collected from the hot springs and the bacterial enrichment was performed in a medium containing rice barn and carboxymethyl cellulose (CMC). The cultures were incubated at 50 °C in

5. Optimization of the production of extracellular α-amylase by Kluyveromyces marxianus IF0 0288 by response surface methodology
The aim of this work was to study the production of extracellular α-amylase by Kluyveromyces marxianus IF0 0288 using optimized nutritional and cultural conditions in a complex yeast medium under aerobic batch fermentation. By applying the conventional "one-variable-at-a-time" approach and the response surface methodology, the effect of four fermentation pa

6. Vinhaça concentrada de cana-de-açúcar: monitoramento das propriedades químicas do solo e mineralização líquida de nitrogênio / Concentrated vinasse from sugarcane: monitoring of soil chemical properties and net nitrogen mineralization
A geração de grande quantidade de vinhaça resultante da produção de etanol induziu questionamentos a respeito de sua disposição e possível armazenamento. No Estado de São Paulo, a norma P4.231 da CETESB restringiu a aplicação de vinhaça em muitos solos, resultando na necessidade de distribuí-la em áreas distantes da usina. Porém, devido a gran

7. Mecanismos moleculares da ação tóxica pró-oxidante de 1,4-diamino-2-butanona, um análogo de putrescina, sobre células de mamíferos e Trypanosoma cruzi / The Molecular mechanisms of pro-oxidant activity of 1,4-diamino-2-butanone, a putrescine analogue, to mammalian cells and Trypanosoma cruzi
α-Aminocarbonyl componds such as 5-aminolevunilic acid (ALA) and aminoacetone (AA) have been shown to exhibit pro-oxidant properties. These compounds undergo phosphate-catalyzed enolization in physiological pH and subsequent aerobic oxidation, yielding reactive oxygen species, NH4+ ions and an α-oxoaldehyde highly cytotoxic. The α-aminoketone 1

8. Seleção de fungos produtores de lipases a partir de resíduos oleosos derivados do saneamento ambiental
The selection of fungi producing lipase from oily residues of environmental sanitation is the main objective of this work. Of 113 fungal isolates obtained, 75 were pre-selected as producers of lipase. Of these,16 were selected by the largest indices enzymatic and four by growth and response to rhodamine-B test, having quantified its specific lipolytic activi

9. Bioprospecção de genes envolvidos na síntese de biossurfactantes a apartir de microbiota de resevatórios de petróleo / Bioprospection of genes involved in the synthesis of biosurfactants from braziliam petroleum reservoirs microbial communities
Bioemulsifiers or biosurfactants are compounds produced by microorganisms which enhance the bioavailability of hydrophobic substances promoting the stabilization of substances with different polarities, like oil-in-water emulsion occurring in petroleum reservoirs. The samples used in this work were collected in the Potiguar Basin (RN, Brazil), and employed a

10. Avaliação da contaminação por microorganismos esporulados e indicadores em requeijão cremoso / Microbiological evaluation of indicators and sporeforms in requeijão cream cheese
The objective of this research was to carry out a microbiological survey of Brazilian cream cheese ?Requeijão? ( pH 5,8 ), production line and to evaluate its shelf life, in relation to contamination by sporeformers and pathogens such as L. monocytogenes, coagulase positive S. aureus and Coliforms ( 45°C) and to determinate the microorganism(s), surviving

11. Enzymatic reactions of Clostridium difficile in aerobic and anaerobic environments with the RapID-ANA II identification system.
The RapID-ANA II anaerobic identification system (Innovative Diagnostic Systems, Inc., Atlanta, Ga.) was used to determine whether the incubation environment affects enzyme detection. Twenty strains of Clostridium difficile were tested in aerobic, anaerobic, and low-CO2 anaerobic incubation environments. The percentages of enzymes detected in reactions with

12. The Effects of Anoxia on the Morphology and Composite Metabolism of the Intact Aortic Intima-Media Preparation
Paired samples of an intact rabbit aortic intima-media preparation were incubated for short periods under aerobic or anoxic conditions in Krebsbicarbonate buffer containing 6% albumin and 5 mM glucose. During aerobic incubation for as long as 1 h the preparation retained an electron microscopic (EM) appearance similar to that of tissue fixed in situ, and sca
