1. Solving ethanol production problems with genetically modified yeast strains
The current world demand for bioethanol is increasing as a consequence of low fossil fuel availability and a growing number of ethanol/gasoline flex-fuel cars. In addition, countries in several parts of the world have agreed to reduce carbon dioxide emissions, and the use of ethanol as a fuel (which produces fewer pollutants than petroleum products) has been

2. Um estudo dos processos de regulação e governança socioambiental do setor sucroalcooleiro no Brasil
In the last five years, there was an increase the ethanol production in Brazil, thanks to the ex-pansion of this sector in the Brazilian Cerrado. Despite all the scientific and technological development for sustainable production of ethanol, the environmental, social and labor also affect the credibility of the product, both domestically and externally. Alon

3. Aspectos biotecnológicos da interação entre bactérias e cana-de-açúcar (Saccharum sp., L.) / Biotechnological aspects of bacteria-sugarcane (Saccharum sp., L.) interactions
Sugarcane is one of the most important Brazilian crops. Its importance is increasing due to the gradual substitution of fossil fuel for renewable and cleaner energy sources, such as ethanol Consequently, the biotechnological aspects that mediate sugarcane-bacterium interactions must be evaluated; studies from tropical countries are incipiente Bacterium-plant

4. Análise dos canais de distribuição do etanol carburante brasileiro: um estudo exploratório
The development of flexible-fuel engines and the necessity of an alternative source of energy to the oil (Petroleum) have leaded the ethanol distribution process into a new configuration. These changes brought forth new opportunities to the Brazilian sugarcane ethanol fuel industry and new directions to the development of ethanol marketing channels in the na

5. Formação de preço de energia elétrica gerada por biomassa no Ambiente de Contratação Livre brasileiro: uma abordagem computacional baseada em agentes / Price setting process of electricity generated by biomass in the brazilian Free Agreement Environment: a computational agent-based approach
Electricity generation in ethanol and sugar mills using bagasse as a fuel in cogeneration process is a traditional practice. In Brazil, since the 1980s mills have evolved to a position of almost self-sufficiency in electricity production, which indicates a strong potential of electricity surplus that can be used as a complement in the electricity national ma

6. O Etanol e a Gasolina sÃo Substitutos Perfeitos? / The Etanol and the Gasoline are Perfect Substitutes?
The relative domestic prices behavior for fuels (relationship among price of ethanol and gasoline) was analyzed accord to panel monthly ones on 27 Brazilian units during the period from July 2001to February 2008. They released by ANP and through Box-Jenkins methodology. It was empirically verified that relative prices seem to follow a first-order autoregress

7. Prospective analysis of the pattern of expansion of the sector sucroenergético Brazil: an application of probabilistic models with data-georeferenciated / Análise prospectiva do padrão de expansão do setor sucroenergético brasileiro: uma aplicação de modelos probabilísticos com dados georeferenciados
With expectations of a growing international market for biofuels, where Brazil would be a natural leader in the ethanol, several questions arise regarding the sustainability of Brazilian ethanol expansion: what would be the environmental, social and economic inpacts of sugarcane expansion in a scenario of significant ethanol exports? What regions would be mo

8. Ethanol storage tanks location in Brazil: a mixed integer program model application / Localização de tanques de armazenagem de álcool combustível no Brasil: aplicação de um modelo matemático de otimização
The main purpose of this research is to develop a mathematical model intended for strategic analysis of the optimal location and considering suitable volumes for storage ethanol (anhydrous and hydrous) tanks. The Mixed Integer Program - MIP model was based on Brazilian ethanol distribution system. The model considered market parameters as supply, demand, and

9. 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

10. A desregulamentação e o desempenho do complexo sucroalcooleiro no Brasil.
This work analyzed the evolution of the relation between the sugar and alcohol complex and the State from 1975 to 2002, when there was a change from public intervention, marked by Proálcool, to a new situation, in which deregulation is proposed. We attempted to interpret the main political and economical stipulators of the process, as well as describe the w
