15. Eficiência agronômica de fertilizantes fosfatados em solos com diferentes capacidades de adsorção de fósforo e teores de matéria orgânica / Agronomic efficiency of phosphate fertilizers in soils with different capacity of phosphate adsorption and organic matter levels
Tropical soils highly intemperized show increased capability on phosphorus (P) adsorption. Several factors may influence P adsorption in such soils, but special attention must be paid on the organic matter level. Mechanisms involved in this process are related to the release of organic acids derived from the decomposition of the organic matter, which may eit

16. Superfosfato triplo, lama vermelha e zeólitas para remediação de metais pesados em solo contaminado / Remediation of contaminated soil with heavy metal using triple superphosphate, red mud and zeolites
Due to the heavy metal persistence in soils, the contamination by these elements is considered permanent and might result in great impact causing a degradation of the chemical and biological properties of the soil. Stabilization techniques have been used as an efficient tool for the remediation of soils that are contaminated by heavy metals, and they show al

17. Iron-limited condition modulates biofilm and adhesive porpoerties in enteroaggregative Escherichia coli / Influência da limitação de ferro nas propriedades adesivas e na formação de biofilme de Escherichia coli enteroagregativa (EAEC)
Escherichia coli enteroaggregative (EAEC) can cause persistent or acute diarrhea. It is characterized by the aggregative adherence pattern on HEp-2 cells, with the presence of bacteria aggregates like stacked bricks. Many strains have the capacity to produce siderophores, low-molecular-mass compounds that capture iron under conditions of low concentration of

18. FE(III) AS ELECTRON ACCEPTOR FOR GASOLINE-ETHANOL BIODEGRADATION IN TROPICAL RESIDUAL SOIL / FE(III) COMO ACEPTOR DE ELÉTRONS NA BIODEGRADAÇÃO DE GASOLINA-ETANOL EM SOLO TROPICAL RESIDUAL
Gasoline monoaromatic hydrocarbons (BTEX) have been detected in aquifers due to storage tank spills from gas stations that lead to their consequent dissolution on groundwater. An aggravating factor in Brazil is ethanol being used as additive to gasoline, promoting an increase on pollutants percolation in soil since it works as co-solvent and is preferentiall

19. Desempenho, carcaça e qualidade da carne de suínos alimentados com ração de elevado nível de ácido fítico e diferentes níveis de fitase
The pork production with low cost, safe and with high quality, identified with the consumer exigencies, and produced with reduced pollution capacity are a current objectives of the segment. There phytase enzyme utilization with the goal to improve the availability of the phytic phosphorus of the grain and the other minerals, reducing losses and ambiental dam

20. Phosphorus dynamics and availability in soils cultivated with production coffee plants, / DinÃmica e disponibilidade de fÃsforo em solos cultivados com cafeeiro em produÃÃo
During many years coffee (Coffee arabica L.) plants have been considered low responsive to phosphorus fertilization. However, recent research data show that these plants demand high phosphorus quantity to fully develop their vegetative and reproductive systems. Aiming to know how phosphorus availability is influenced by annual P doses and how they may influe

21. Regulação da expressão gênica por oxigênio no fungo aquático Blastocladiella emersonii / Regulation of gene expression by oxygen in the aquatic fungus Blastocladiella emersonii
In this work we analyzed global gene expression changes in the aquatic fungus Blastocladiella emersonii submitted to oxygen deprivation (hypoxia), using cDNA microarrays containing 3,773 distinct genes. In gradual hypoxia (gradual decrease in dissolved oxygen concentration, followed by reoxygenation) and direct hypoxia (direct decrease of dissolved oxygen co

22. Development of alternative nutritional formulas for elderly enteral nourishment using conventional foods / Elaboração de formulados nutricionais alternativos a partir de alimentos convencionais para a alimentação de idosos
The aim of this study was to develop alternative formulas for elderly enteral feeding using conventional foods from food staples distributed in the city of Piracicaba-SP. The foods used in the formulas were: corn meal, soya oil, rice, beans, pasta, sardine, powder milk, corn starch, eggs, texturized soya protein, cabbage, and carrot. Physical analyses (dripp

23. BIOCHEMICAL AND PHYSIOLOGICAL EVALUATION OF POTATO CLONES IN RELATION TO ALUMINUM / AVALIAÇÃO BIOQUÍMICA-FISIOLÓGICA DE CLONES DE BATATA EM RELAÇÃO AO ALUMÍNIO
Aluminum (Al) is the most abundant metal in the earths crust, affecting thegrowth and development of plants. The objective of this work was to investigate and compare biochemical and physiological responses of potato clones, Macaca, SMIC148-A, Dakota Rose and Solanum microdontum, exposed to 0, 50, 100, 150 and 200 mg Al L-1 in nutrient solution (pH 4.0).

24. Concentração de proteínas (fosvitina e lipovitelina) em gemas de ovos de galinhas (Gallus gallus) nos diferentes ciclos de postura e sua interferência na disponibilidade do ferro / Protein concentration (phosvitin and lipovitelin) in egg yolks of hens (Gallus gallus) in the different cycles of position and its interference in the availability of the iron
The egg is the product of efficient biological transformation made by the hens of position, with high nutricional quality for the human consumption. In the egg yolk of the egg it meets phosvitin called protein, the same one acts as hauled of the iron if binding it. The iron deficiency normally occurs due to the insufficient food consumption iron sources or l
