25. Fungi biodegradation of vinasse from industrial sugarcane processing / Biodegradação de vinhaça proveniente do processo industrial de cana-de-açúcar por fungos
Vinasse is a residue resulting from the production of alcohol after pulp fermentation and distillation of the wine, ensuing from 10 to 15 liters for each liter of ethanol produced. This high colored effluent is a by-product rich in nutrients, mainly organic matter, having a high pollutant potential when disposed in the environment. Lignolytic fungi can be ut

27. Estudo de uma metodologia para estimar a quantidade de carbono em amostras de solo utilizando espectroscopia de emissão óptica com plasma induzido por laser (LIBS) / Study of a methodology to estimate the carbon content in soil samples by laser induced breakdown spectroscopy (LIBS)
Soils are an important component in the biogeochemical cycle of carbon, storing about four times more carbon that biomass plants and nearly three times more than the atmosphere. Moreover, the carbon content is directly related on the capacity of water retention, fertility, among others properties. Thus, soil carbon quantification in field conditions is an im

28. Utilização do metano como doador de elétrons para remoção de nitrogênio via nitrificação e desnitrificação em reator operado em bateladas seqüenciais / Nitrogen removal by biological nitrification and denitrification using methane as electron donor in a sequencing batch aerobic/anoxic reactor
Nitrogen removal via biological nitrification and denitrification was studied in a sequencing batch reactor submitted to aerate and anoxic periods. Methane was added as electron donor for denitrification in the anoxic periods. Different operational and nutritional conditions referred to as stages in this text were tested aiming to achieve the best nitrogen r

31. "Metodologia para Determinação de Hidrocarbonetos Policíclicos Aromáticos em Sedimentos e Solos Periféricos à Represa São Pedro Juiz de Fora, MG"
Polycyclic Aromatic Hydrocarbons are important substances that are produced by many antropogenic sources, among that, the most significant is burns of fossil fuels and biomass which releases these compounds to the environment. Sediments and soils are important matrix to study contamination and their effects because they are able to adsorb organic compounds s

33. Quantificação do estoque de biomassa e análise econômica da implementação de projetos visando a geração de créditos de carbono em pastagem, capoeira e floresta primária / Biomass stock estimation and economic analysis of implementation of projects seeking carbon credit generation in pastures, secondary and primary forests
The lack of studies on quantification of biomass and sequestered carbon in the Atlantic Forest biome and the increasing demand for Clean Development Mechanism (CDM) projects motivated the execution of this study, aiming at quantifying the biomass and carbon stock of an Atlantic Forest fragment and evaluating the economic viability of five scenarios (Afforest

34. Extração, purificação e caracterização de polissacarídeos da biomassa do fungo ascomiceto Botryosphaeria rhodina MAMB-05
The composition of the polysaccharides constituting the biomass of the ascomyceteous fungus, Botryosphaeria rhodina MAMB-05, cultivated on glucose as carbon source was investigated following separation of the exopolysaccharides (EPS). Fungal mycelial biomass was exhaustingly washed with water at room temperature until no residual sugars could be detected (ph
