1. FIXAÇÃO DE CO2 EM EFLUENTE SALINO DE INDÚSTRIA PETROQUÍMICA
In various industrial processes, such as the process of obtaining potassium by solution mining or in the oil industry, fuels are burnt concurrently to the formation of saline effluents. The opportunity to sequester carbon through capturing the CO2 from the flue gas by carbonation of these effluents and reducing the potential of scaling of the water is eviden

2. Equações de biomassa e estoques de carbono de seis espécies em plantios mistos no noroeste do Mato Grosso
During this time of discussion about global warming and climate change, environmental restoration projects thought as a CO2 sink in its plant biomass are essential in the fighting the increasing concentration of global warming greenhouse gases. One very eficient method to sequester atmosphere carbon is through reforestation and quantifying the resulting stan

3. Forestry restoration and carbon stock in seedlings implantation models under different combinations of species and spacing / Restauração florestal e estoque de carbono em modelos de implantação de mudas sob diferentes combinações de espécies e espaçamentos
Além dos já conhecidos benefícios da conservação e restauração das florestas ciliares sobre a qualidade e quantidade de água produzida pelas microbacias hidrogáficas, atualmente apregoa-se também a essas florestas a função de sumidouro de carbono. Este trabalho desenvolvido em duas propriedades produtoras de cana-de-açúcar localizadas no Norte

4. Carbono do solo e a mitigação da mudança climática global
The soils of the world contain more carbon than the combined total amounts occurring in vegetation and the atmosphere. Hence soils are a major reservoir of carbon in terrestrial ecosystems and an important sink. Recently, emphasis has been placed on the need to sequester carbon from atmospheric carbon dioxide into soil organic matter because of international

5. Curbing the U.S. carbon deficit
The U.S. emitted ≈1.58 petagrams (Pg) of fossil fuel carbon in 2001, approximately one-quarter of global CO2 production. With climate change increasingly likely, strategies to reduce carbon emissions and stabilize climate are needed, including greater energy efficiency, renewable energy sources, geoengineering, decarbonization, and geological and biologica

6. Degradation Pathway and Generation of Monohydroxamic Acids from the Trihydroxamate Siderophore Deferrioxamine B
Siderophores are avid ferric ion-chelating molecules that sequester the metal for microbes. Microbes elicit siderophores in numerous and different environments, but the means by which these molecules reenter the carbon and nitrogen cycles is poorly understood. The metabolism of the trihydroxamic acid siderophore deferrioxamine B by a Mesorhizobium loti isola

7. Phytoremediation of methylmercury pollution: merB expression in Arabidopsis thaliana confers resistance to organomercurials
Methylmercury is an environmental toxicant that biomagnifies and causes severe neurological degeneration in animals. It is produced by bacteria in soils and sediments that have been contaminated with mercury. To explore the potential of plants to extract and detoxify this chemical, we engineered a model plant, Arabidopsis thaliana, to express a modified bact

8. Influence of Mannose on the Apoplasmic Retrieval Systems of Source Leaves 1
Experiments were conducted in which d-mannose was supplied to mature Beta vulgaris L. (sugar beet) leaves, via the transpiration stream, to perturb photosynthetic carbon allocation by sequestering cytosolic Pi. Biochemical and enzymic analyses conducted on this tissue indicated that mannose 6-P was present, that it was only slowly metabolized, and that after

9. Convergent evolution of chemical defense in poison frogs and arthropod prey between Madagascar and the Neotropics
With few exceptions, aposematically colored poison frogs sequester defensive alkaloids, unchanged, from dietary arthropods. In the Neotropics, myrmicine and formicine ants and the siphonotid millipede Rhinotus purpureus are dietary sources for alkaloids in dendrobatid poison frogs, yet the arthropod sources for Mantella poison frogs in Madagascar remained un
