Abstract

The Amazon forest represents an enormous importance of biodiversity and biome balance. However, in the last decades, the anthropic activities have increased causing a vast decrease of resident biodiversity. A couple of consequences about these changes are in the hydrological cycles, in the global temperature and in the released greenhouse gases, as methane. The methane is a compost that participates in soil biochemical cycles, especially in the carbon cycles where it acts in several vital processes as an important energetic molecule. An aggravating ambient issue that is currently known is an imbalance between the methane produced and the methane consumed. This project has as target to analyze the functional diversity of methanotrophic organisms in the amazon soil comparing Primary forest, Secondary forest, and pastures areas. The analysis methods will be grounded in independent strategies cultivation, as molecules techniques, that will allow the construction of a representative genetic database of the studied organisms. Accordingly, it is expected that this project could improve the knowledge about methanotrophic organisms in amazon soil and the development of new technologies. (AU)
