1. THE SUCCESS OF THE BRAZILIAN ALCOHOL PROGRAM (PROÁLCOOL) - A DECADE-BY-DECADE BRIEF HISTORY OF ETHANOL IN BRAZIL
ABSTRACT The National Alcohol Program (Proálcool) was a strategic policy of the Brazilian government to replace petroleum-based fuels with alcohol (ethanol). Based on the review, we can choose the 1960s as a start point for a leap in development. Over the 500 years of sugarcane history in Brazil, the crop enters the second decade of the 21st century with ex

2. Mecanização e intensificação do trabalho no corte de cana do CAI canavieiro do estado de São Paulo
Assuming that the work is the central category in the production process, the relationship between the recent modernization, in special in the harvesting activities, and the manual harvesting work intensification were studied in the Sugarcane Agroindustrial Complex of São Paulo State. The work intensification, which involves high energy expenditure by the w

3. A migração piauiense e as atividades sucroalcooleiras em Morro Agudo (SP)
A cana-de-açúcar trouxe o desenvolvimento a muitos municípios paulistas, tornando-se, ao longo dos anos, uma característica marcante daquele estado. O município de Morro Agudo (SP), localizado na Mesorregião de Ribeirão Preto, possui uma população de 29.127 habitantes, de acordo com o Censo Demográfico de 2010. Desses, 95,85% residem na área urban

4. Evaluation of activated vegetal charcoal and vegetal polymer on the detoxification of the sugarcane hemicellulosic hydrolysate for biotechnological production of xylitol / Avaliação do carvão vegetal ativado e polímero vegetal na destoxificação do hidrolisado hemicelulósico de bagaço de cana-de-açúcar para a produção biotecnológica de xilitol
The increasing search for ethanol fuel in order to reduce the dependence and to promote the substitution of fossil fuels will contribute to higher accumulation of sugarcane bagasse in the environment. This biomass that in Brazil is a by-product of the sugar-alcohol mills, although it has been used for the generation of energy in the sugar and alcohol product

5. Biomassa e energia
Biomass was the dominating source of energy for human activities until the middle 19th century, when coal, oil, gas and other energy sources became increasingly important but it still represents ca. 10% of the worldwide energy supply. The major part of biomass for energy is still "traditional biomass" used as wood and coal extracted from native forests and t

6. The determinants of sugar and alcohol supply in Paranà State (1981 to 2006): an analysis of cointegration / Determinantes das ofertas de aÃÃcar e de Ãlcool paranaenses (1981 a 2006): uma anÃlise de co-integraÃÃo
The beginning of 90s is marked by a new dynamic of Brazilian sugar cane agribusiness. The disconnection of the State apparatus, which was responsible for the activities management at that time, forced the sector to an adjustment in a free market context that, since then, has been experiencing significant advances, both in internal and external markets. The i

7. Microrganismos promissores para a degradação de compostos fenólicos presentes em bagaço-de-cana, lodo e águas residuárias de agroindústria sucro-alcooleira. / Promising microorganisms for the degradation of phenolic compounds present in sugarcane bagasse, mud and wasterwater of the sugar-alcohol agroindustry
Eight strains of bacteria (L1-L8) were isolated from the mud of a decantation lake (A) from the Station of Effluent Treatment (SET) of the S. A. Usina Coruripe Açúcar e Álcool, in the harvest season of 2004/05. Three of these bacteria were considered facultative anaerobes (L3, L7 and L8). The isolates were identified as species of the genus Achromobacter

8. Hidrolases e fenoloxidases de microrganismos como marcadores para seleção de biosuplementadores e avaliação do tratamento sobre efluentes sucroalcooleiros
Due to the current and future problematic of the maintenance of the hydric resources, the reuse of waters after previous treatment has been a strategy in the management of aquifers. The bioaugmentation is one of the techniques of purification of effluents and, because of this, studies were carried out in lagoons from the station of treatment of effluents (ST

9. Avaliação do ciclo de vida do álcool etílico hidratado combustível pelos métodos EDIP, exergia e emergia / Life cycle assessment of hydrated ethylic alcohol fuel by EDIP, exergy and emergy methods
One of the most integrated, complete and efficacious means for the environmental management of productive activities is based on the life cycle of the product, whose main tool is the life cycle assessment. The assessed product is the hydrated ethylic alcohol fuel because of the environmental improvement possibilities during its life cycle, an alternative for

10. Mobilização de xiloglucano de reserva em sementes de Hymenaea courbaril L
Some species of Leguminosae accumulate high amounts of polysaccharides in the seed. These polysaccharides are translocated to the embryo after the germination, being an important source of carbon and energy to the developing plantlet. Seeds of Hymenaea courbaril L. store up to 40% of the seed mass in the form of xyloglucan deposited in the walls of parenchym

11. Sintese de novos combustiveis solidos a partir de residuos agroflorestais e possiveis contribuições no cenario energetico brasileiro
Agricultural activities and wood exploitation either in natural or planted forests in Brazil, generate a large amount of vegetables residues, along with the main product. Usually these residues have not a correct use, being in most of the times either burned or abandoned on the field, becoming this way an energy waste, that should be used more conveniently,

12. Influence of invertase activity and glycerol synthesis and retention on fermentation of media with a high sugar concentration by Saccharomyces cerevisiae.
In the past, the fermentation activity of Saccharomyces cerevisiae in substrates with a high concentration of sucrose (HSuc), such as sweet bread doughs, has been linked inversely to invertase activity of yeast strains. The present work defines the limits of the relationship between invertase activity and fermentation in hyperosmotic HSuc medium. Fourteen po
