1. Anthropogenic impacts on aquatic bacteria: a perspective from the tropics
Resumo O bacterioplâncton compreende um grupo altamente diversificado de microrganismos, que são dominantes nos ecossistemas aquáticos e desempenham um papel central no funcionamento desses ecossistemas e nos ciclos biogeoquímicos. Devido às suas elevadas taxas de dispersão e de mudança na composição, bem como alta adaptabilidade e plasticidade, os

2. 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

3. Antifungal Polyketides and Other Compounds from Amazonian Endophytic Talaromyces Fungi
The continuous search for biologically active compound candidates pushes the pursuit of new substances produced by diverse organisms. Endophytic fungi are known as a promising source of metabolites with several biological activities. Based on the rich Amazonian biodiversity and the chemical potential of microbial sources, three Talaromyces strains, all major

4. Microbial Symbionts of Insects are the Focus of the First International Cooperative Biodiversity Group (ICBG) in Brazil
The basic aim of the ICBG (International Cooperative Biodiversity Group) program is to benefit both the host country and the global scientific community by discovering and developing new solutions to human health problems based on previously unexplored genetic resources. The first ICBG in Brazil is jointly supported by the Fogarty International Center of the

5. Occurrence of culturable soil fungi in a tropical moist deciduous forest Similipal Biosphere Reserve, Odisha, India
Similipal Biosphere Reserve (SBR) is a tropical moist deciduous forest dominated by the species Shorea robusta. To the best of our knowledge their rich biodiversity has not been explored in term of its microbial wealth. In the present investigation, soil samples were collected from ten selected sites inside SBR and studied for their physicochemical parameter

6. Soil health: looking for suitable indicators. What should be considered to assess the effects of use and management on soil health?
Soil Health refers to the ecological equilibrium and the functionality of a soil and its capacity to maintain a well balanced ecosystem with high biodiversity above and below surface, and productivity. To understand and use soil health as a tool for sustainability, physical, chemical, and biological properties must be employed to verify which respond to the

7. Química Sem Fronteiras: o desafio da energia
Coal, natural gas and petroleum-based liquid fuels are still the most widely used energy sources in modern society. The current scenario contrasts with the foreseen shortage of petroleum that was spread out in the beginning of the XXI century, when the concept of "energy security" emerged as an urgent agenda to ensure a good balance between energy supply and

8. Micro-organismos de interesse farmacêutico e agrícola: estudo químico e biossintético / Microorganisms of pharmaceutical and agricultural interests: chemical and biosynthetic studies
The microbial biodiversity from different ecosystems has incited chemical and biological studies with microorganisms from several habitats, leading to the isolation of bioactive natural products with applications in medicine, chemical industry and agriculture, and thus contributing to a better quality of life. This thesis aimed the biopropecting on endophyti

9. Biodiversity of the oleaginous microorganisms in Tibetan Plateau
Microbial lipids, which are also known as single cell oils (SCO), are produced by oleaginous microorganisms including oleaginous bacteria, yeast, fungus and algae through converting carbohydrates into lipids under certain conditions. Due to its unique environment having extremely low temperature and anoxia, the Tibetan Plateau is amongst the regions with num

10. 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

11. Diversidade e estrutura da comunidade bacteriana associada às armadilhas da planta carnívora Utricularia gibba (Lentibulariaceae) e ao ambiente aquático. / Diversity and structure of bacterial communities associated to the traps of the carnivorous plant Utricularia gibba (Lentibulariaceae) and aquatic environment.
A diversidade microbiana em ambientes aquáticos e sua associação com plantas carnívoras ainda é pouco estudada. Assim, a comunidade bacteriana da planta carnívora Utricularia gibba e do seu meio aquático foi avaliada por meio do seqüenciamento em larga escala (454 Roche) de uma biblioteca do gene 16S rRNA. Os resultados indicaram que a comunidade bac
