1. Effects of trees and nitrogen supply on the soil microbiological attributes on integrated crop-livestock systems
ABSTRACT The diversification of plants, as an association between trees and the warm-season grasses, supports soil biodiversity and thus, soil quality. However, based on the prevailing climatic conditions, management techniques employed and because of the several combinations possible in such associations, variations may be observed in this type of respons

2. Soil Macrofauna as a Soil Quality Indicator in Native and replanted Araucaria angustifolia Forests
ABSTRACT Studies on soil quality in Araucaria forests contribute to understanding changes in this ecosystem and serve as a tool in conserving its biodiversity. The aim of this study was to evaluate the potential of soil macrofauna in discriminating native and replanted Araucaria forests for selection of soil quality indicators. Native (NF) and replanted (RF)

3. Physical and chemical quality, biodiversity, and thermodynamic prediction of adhesion of bacterial isolates from a water purification system: a case study
ABSTRACT The objective of this study was to evaluate the quality of water purification system and identify the bacteria this system, predict bacterial adherence according to the hydrophobicity of these microorganisms and of the polypropylene distribution loop for purified water. The assessment of drinking water that supplies the purification system allowed g

4. Diversidade de fungos micorrízicos arbusculares em pomar orgânico no semiárido cearense
The arbuscular mycorrhizal fungi (AMF) are key-organisms for maintenance of plant biodiversity in agroecosystems. There is an increasing interest in changes of the microbiological properties in the rhizosphere by its practical and environmental relevance. This research aimed to evaluate the occurrence of AMF in the establishment of fruits under organic manag

5. Microbiological biodiversity in poultry and paddy straw wastes in composting systems
Immense quantity of waste is generated in association with poultry meat egg and crop production. The potential risks due to disposal of these wastes are magnified as a result of dense refinement of poultry production and the decreasing amount of land available for waste disposal. The study aims at studying the microbiological biodiversity of poultry waste an

6. Oxidação microbiológica do enxofre elementar no solo / Microbiological elemental sulfur oxidation in soil
Reduções dos níveis de sulfato nos solos vêm sendo observadas em função de práticas agrícolas e exportação de biomassa. O enxofre Elementar (S0) pode ser usado como fertilizante, contudo para ser absorvido pelas plantas deve ser antes oxidado a sulfato. A oxidação microbiológica do S0 está associada com Acidithiobacillus thiooxidans, apesar de

7. Caracterização de leveduras do gênero Trichosporon isoladas de três regiões costeiras do Estado de São Paulo / Characterization of Trichosporon spp. Isolated from three coastal regions of São Paulo State, Brazil
Coastal regions are being threatened because they have a predatory and uncontrolled exploitation of natural resources by changing biodiversity. Yeasts are part of the marine ecosystem, though some species are associated with superficial mycoses, subcutaneous and / or systemic. The objective of this study was to quantify yeast, isolation and Trichosporon spp.

8. Polyketide biosynthetic gene bioprospection in metagenomic DNA from Atlantic Forest soil. / Bioprospecção de genes biossintéticos de policetídeos em DNA metagenômico de solo de Mata Atlântica.
The Brazilian Atlantic Forest is considered as one of the most important reservoir of biodiversity in the planet. This biome is extremely important for its richness of plant and animal species but although with their composition and interactions poorly known and unexplored from a microbiological perspective. One gram of soil can contain near 10 billion micro

9. Isolamento e identificação de actinobacterias em solos de terra preta antropogenica (TPA) da Amazonia Central por ARDRA e sequenciamento do gene 16S rRNA. / Isolation and identification of actinobacteria in anthropogenic dark earth of Central Amazon by ARDRA and seguencing of 16S rRNA gene.
Actinomycetes have been especially useful in the pharmaceutical industry for their unlimited capacity to produce secondary metabolites with diverse chemical structures and biological activities. The search for novel species of actinomycetes constitutes an essential component for the discovery of new pharmaceutical drugs. Actinomycetes are widely distributed

10. Analysis of environmental sustainability of the superficial freshwater classification system / Análise da sustentabilidade ambiental do sistema de classificação das águas doces superficiais
Brazil is a country endowed with great superficial water reserves and aquatic biodiversity, despite its unequal distribution among diverse hydrographic regions. In view of the sustainable development concept established in many international environment and water treated, objectified to the aquatic ecosystems preservation and the equitable distribution of th
