1. Selection of Xilose-Fermenting Yeast Strains
ABSTRACT In Brazil, ethanol is obtained by fermentat of sugar cane juice using Saccharomyces cerevisiae. The cane juice extraction generates the bagasse that has been used for obtaining generation biofuel. However, the sugarcane bagasse has 30% pentose that cannot be fermented to ethanol by S. cerevisiae. Thus the aim of this study was to isolate a yeast abl

2. Métodos para preservação de urediniósporos de Puccinia Kuehnii
Among the diseases of the culture of sugarcane in Brazil stands out the rusts. Currently, the most worrying is the orange rust due their potential for harm. The objectives were to test the feasibility periods of uredinósporos, preservation methods and influence of aqueous extracts in the in vitro germination urediniospores of Puccinia kuehnii.The work was d

3. Sugar cane bagasse prehydrolysis using hot water
Results are presented on the hot water prehydrolysis of sugar cane bagasse for obtaining ethanol by fermentation. The experimental study consisted of the determination of the effect of temperature and time of prehydrolysis on the extraction of hemicelluloses, with the objective of selecting the best operating conditions that lead to increased yield of extrac

4. A fração volátil das aguardentes de cana produzidas no Brasil
The volatile fraction of sugar cane spirits plays a key role in the quality and acceptance of these beverages. The composition of this fraction is dependent on the way sugar cane collection, fermentation, distillation and aging are carried out. The materials used in these processes strongly influence chemical composition. Acetic acid, acetaldehyde, ethyl ace

5. Extraction of lignin from sugar cane bagasse and its modification into a high performance dispersant for pesticide formulations
Com o objetivo de utilizar efetivamente um sub-produto de material não madeireiro, foi extraída lignina do bagaço de cana-de-açúcar via acidificação do licor negro. A lignina extraída do bagaço da cana-de-açúcar (EBL) foi modificada por oxidação, hidroximetilação e sulfonação em um lignossulfonato solúvel em água (EBL-M). O composto foi ca

6. Processo simplificado para a produção de concentrado de acidos graxos de cadeia longa (D-003) a partir da cera de cana-de-açucar (Saccharum officinarum L.) / Simplified process to production of concentrated long chain fatty acids from sugar cane wax (Saccharum officinarum L.)
The sugar cane (Saccharum officinarum L.) wax obtained from filter cake, a byproduct of the sugar and alcohol industries, has attracted great interest due to the large potential for application in various industrial sectors, including the pharmaceutical industry. Brazil is the largest sugar cane producer and sugar exporting country in the world, making it a

7. AvaliaÃÃo das concentraÃÃes de elementos quÃmicos nos sedimentos de fundo do estuÃrio do Rio Formoso (PE)
The estuary of Formoso river is located in the south coastal zone of the Pernambuco state, in an environmental protection area, named APA of Guadalupe. This is an important coastal ecosystem with a rich biodiversity, which plays an important socioeconomic role for the local population. Anthropogenic activities such as shrimp farming, sugar cane cultivation,

8. Dinâmica de nutrientes na cana-de-açúcar em sistema irrigado de produção
One of the main investments in the alcohol and sugar sector is the technological innovations searching for increments in the productivity of the sugar cane fields, as an example, the genetic improvement of the sugar cane producing new varieties more productive and environmentally adapted. The productive capacity of these varieties, however, may have being un

10. 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

11. Balanço de nitrogênio e enxofre no sistema solo-cana-de-açúcar no ciclo de cana-planta / Nitrogen and sulfur balance in the soil-sugarcane system during the plant cane cycle
This works objective was to evaluate the use and distribution of nitrogen and sulfur added to the soil as fertilizers in the soil-sugarcane system (plant cane), using the stable isotopes 15N and 34S. The study also aimed to evaluate the contribution of nitrogen mineralized from sugar cane crop residues labeled with 15N and incorporated into the soil, in a co

12. Desenvolvimento e caracterizaÃÃo de gel de biopolÃmero produzido pela fermentaÃÃo de melaÃo da cana-de-aÃÃcar pelo microorganismo Zoogloea sp. Contendo Ãcido Ãsnico
An exopolysaccharide produced by Zoogloea sp. from sugar cane molasses as a fibrous membrane was used to prepare a gel containing usnic acid, which presents antimicrobial activity. A method of drug extraction from the biopolymer gel was validated. The usnic acid, pure and drug-loaded biopolymer gel were characterized through differential scanning calorimetry
