1. Cachaça Production in Brazil and its Main Contaminant (Ethyl Carbamate)
ABSTRACT This review aims to demonstrate the possible formation of Ethyl carbamate (EC) in different production stages of cachaça. EC is a carcinogen confirmed in animal experiments and possibly carcinogenic to humans. EC incidence below relevant health limits naturally affects many fermented foods and beverages. Concentrations above 1 mg L–1 are often de

2. Waterlogging-induced changes in fermentative metabolism in roots and nodules of soybean genotypes
Waterlogging blocks the oxygen supply to the root system which inhibits respiration, and greatly reduces the energy status of cells that affect important metabolic processes. This study evaluated fermentative metabolism and carbohydrate contents in the root system of two soybean (Glycine max L. Merril) genotypes under hypoxic and post-hypoxic conditions. Nod

3. Biofertilizante de rochas mais matéria orgânica inoculada com bactéria diazotrófica na cana-de-açúcar.
Sugarcane (Saccharum spp.) Is currently considered one of the most important crops in the Brazilian social and economic. In Pernambuco, the sugar cane industry occupies an important agricultural area with high sugar and ethanol, generating many direct and indirect jobs. For increased productivity becomes necessary the use of management technologies that fost

4. Análise do microtranscritoma em variedades de cana-de-açúcar (Saccharum spp.) submetidas a estresse hídrico / Microtranscriptome analysis of sugarcane (Saccharum spp.) cultivars under drought stress
Sugarcane (Saccharum spp.) is amongst the most relevant crops in the world and Brazil is the most prominent producer. It is an inexpensive and efficient source for commodities such as sugar and ethanol, the latter being increasingly considered the most promising immediate energy source substitute for oil, mainly in transportation. Apart from being very produ

5. Limites e possibilidades do balanço social
In the process of dissemination of social and environmental practices, companies have realized that sugarcane social responsibility initiatives can be used to reduce costs, increase competitive advantage, manage risk and reputation and turned the green initiatives on business strategies. Thus, sugarcane industry use monitoring mechanisms and accountability s

6. Integração das principais tecnologias de obtenção de etanol através do processamento de celulose (2ª geração) nas atuais usinas de processamento de cana-de-açúcar (1ª geração). / Integration of ethanol production technologies throw the cellulose processing (2nd generation) on existing sugar cane processing units (1st generation).
The demand for energy has been increasing due to world development. Renewable energy of biomass, biofuel and electric energy have an important role to assist this growth, due to sustainable development policies and to the pressure of global organizations. The main aim of this dissertation is to demonstrate that the integration of second-generation technologi

7. Comparative analysis of financial and economic viability of installing sugar cane ethanol plants in the North of Goias and Sao Francisco Valley/BA regions: a case study / Análise comparativa da viabilidade econômico financeira para instalação de destilaria de etanol de cana-de-açúcar no Norte de Goiás e no Vale do São Francisco/BA: um estudo de caso
Esta dissertação tem como objetivo mensurar e comparar a viabilidade econômico financeira para a implantação de destilaria com unidades cogeradoras de energia elétrica anexas em duas regiões de expansão da cana-de-açúcar no Brasil: o Norte de Goiás, representado pela cidade de Uruaçu/GO; e o Vale do São Francisco, no semiárido nordestino, repre

10. Avaliação de coeficientes de rendimento e modelagem do processo fermentativo de produção de etanol
The yield ethanol (hP) is one of the most important parameters to be evaluated in the industrial process of alcohol fermentation. Because most plants neither present a reasonable level of automation, nor perform frequent analytical measures during the batch, the hP is currently calculated by methodology based on by-products formed in the process. Such calcul

11. Avaliação da Sustentabilidade do Biodiesel de Soja no Brasil
Biodiesel production in Brazil is currently being sustained mainly by soybean cultivation, mixed with methanol. There is a discussion about the possibility of this soybean-based production can contribute to develop the country in a sustainable manner, taking into account social, economic, environmental and strategic aspects. On the other hand, all those rela

12. Use of a biofuel obtained from the fast pyrolysis of sugarcane trash in an Otto engine / Uso de biocombustivel da pirolise rapida da palha de cana em um motor de ciclo Otto
In September 2002 the state of São Paulo promulgated the Law Nº 11241 by which was codified the gradual elimination of fire as a method to remove trash from the sugar-cane fields before harvestig. Large amounts of sugar-cane trash with an important energy potential will be available as a result of this law. New technologies to harvest and process this biom
