1. Crescimento e capacidade de biosorção de metais por Pleurotus sajor-caju, em cultivo líquido e em cultivo sólido
In this work, Pleurotus sajor-caju PS2001 was cultivated in solid-state, in a medium formulated with sawdust of Pinus spp and wheat bran, to which had been added cupric sulphate, manganese sulphate and ammonium sulphate. Different treatments had been made with these salts, aiming at the solid cultive medium otimization for attainment of bigger productivity i

2. Dinâmica do nitrogênio na cultura do milho (Zea mays L.), em cultivo sucessivo com aveia preta (Avena strigosa), sob implantação do sistema plantio direto / Nitrogen dynamics in maize (Zea Mays L) and black oats (Avena srigosa) successive cropping under the introduction of the no-tillage system
The general objective of this work was to study the dynamics of nitrogen in the soil-plant system of two maize crops with a black oats one in between, introducing the no-tillage system. Besides, fertilizing the first maize crop with 15N enriched nitrogen fertilizer, it was also objective of this work to assess the total and the derived from fertilizer nitrat

3. Destino do nitrogênio (15N) do fertilizante em uma cultura de café / The fate of fertilizer nitrogen (15N) in a coffee crop
The coffee is one of the most important agribusiness products of Brazil and, although its management practices are already well defined, several cropping aspects still need a deeper understanding. Among these the nutrition of the coffee plant in respect to nitrogen is one of the main subjects needing more clarification. To contribute to this aspect, several

4. Purificação e caracterização de uma β-glucuronidase extraída do molusco mesogastropoda ampularidade Pomacea sp
This work studies the involved enzymatic way in the metabolism of glycosaminoglycans sulfateds in the mollusc Pomacea sp. Had been identified endoglycosidases and exoglycosidases in the enzymatic extract of the mollusc Pomacea sp by means of hydrolysis activity in condroitim sulphate of whale cartilage and of the p-Nitrofenil-β-glucuronide, respectively

5. Nitrogênio e enxofre na recuperação de pastagem de capim-Braquiária em degradação em Neossolo Quartzarênico com expressiva matéria orgânica / Nitrogen and sulphur for the recovery of a Signal grass under degradation in on Entisol with expressive organic matter content
Nitrogen is required for pastures establishment, maintenance and production recovery, and its effect has depended on sulphur supply, for the relationship between these nutrients in plant metabolism. The objectives were: a) to study the combinations between nitrogen and sulphur rates in soil with Signal grass (Brachiaria decumbens) under degradation; b) to ev

6. PurificaÃÃo e caracterizaÃÃo da lectina da vagem de Caesalpinia ferrea (cfepl): aplicaÃÃo biolÃgica
Lectins are proteins that bind specifically and reversibly to carbohydrates. Caesalpinia ferrea is a leguminous tree widely distributed in Brazil used in popular medicine. The aim of this work was the purification and characterization of C. ferrea pod lectin (CfePL). Pod extract (E) in 0.15 M NaCl was partially purified on activated charcoal followed by ammo

7. Produção de [beta]-1,3 glucanases, proteases liticas e quitinases por microrganismos e aplicação na lise de leveduras
The aim of this work was the study of b-1,3 glucanases, proteases and chitinases production by B1, B22, B26, FXX, Oerskovia sp. nO4 and Cellulomonas cartae nº191 strains in culture media containing differents inductors as well as their application on yeast cell lysis. The strains B26 and Cellulomonas cartae nO191 showed highest protease production using the

8. Isolamento, caracterizaÃÃo parcial e atividades biolÃgicas da lectina de entrecasca de aroeira (Schinus terebinthifolius Raddi.)
Bark infusions of Schinus terebinthifolius Raddi., Anacardiaceae family (aroeira), have been commonly used in popular medicine. Lectins constitute a heterogeneous protein group capable of recognizing and reversibly bind to carbohydrates. The aim of this work was to isolate a bark lectin from S. terebinthifolius and to evaluate its biological properties. Extr
