13. Characterization of immobilized biomass by amplified rDNA restriction analysis (ARDRA) in an anaerobic sequencing-batch biofilm reactor (ASBBR) for the treatment of industrial wastewater
The performance of an anaerobic sequencing-batch biofilm reactor (ASBBR- laboratory scale- 14L )containing biomass immobilized on coal was evaluated for the removal of elevated concentrations of sulfate (between 200 and 3,000 mg SO4-2·L-1) from industrial wastewater effluents. The ASBBR was shown to be efficient for removal of organic material (between 90%

14. Estudo da tratabilidade de efluente de reator anaeróbio e lixiviado de aterro sanitário utilizando o processo de lodos ativados / Treatability of the anaerobic effluent and landfill leachate using activated sludge process
Embora em alguns países como os europeus, o aterro sanitário como forma de disposição final de Resíduos Sólidos venha perdendo espaço, entre nós essa técnica é ainda largamente empregada. O lixiviado gerado nos aterros sanitários apresenta grande potencial poluidor, devido à presença de matéria orgânica, rica em substâncias húmicas e matéri

15. Microbiological monitoring mf mineral water commercialized in Brazil
The quality of mineral water commercialized in Brazil regarding the microbial content was analyzed and the results were compared with the standards established by the current legislation. Results demonstrated there was no bacterial contamination, but several types of fungi were found. Therefore, bottled mineral water could be considered a possible route for

16. Avaliação qualitativa e quantitativa da microbiota do solo e da fixação biológica do nitrogênio pela soja.
O objetivo deste trabalho foi definir, para as condições edafoclimáticas do Brasil, níveis aceitáveis de dispersão de alguns parâmetros biológicos, utilizados em estudos de impacto ambiental de novas tecnologias usadas na cultura da soja. Dois ensaios com soja convencional e transgênica foram conduzidos em 11 municípios de seis estados e no Distrit

17. Conjunto mínimo de parâmetros para avaliação da microbiota do solo e da fixação biológica do nitrogênio pela soja.
O objetivo deste trabalho foi avaliar e validar um conjunto mínimo de parâmetros para o monitoramento, em campo, da microbiota do solo e da fixação biológica do N2 (FBN) pela soja. Os ensaios foram conduzidos em áreas de plantios comerciais (safra 2002/2003) e experimentais (safra 2004/2005), em blocos ao acaso. O C e o N da biomassa microbiana (CBM e

19. Síntese de regioisômeros quirais a partir de D-manitol: obtenção de uma mistura de álcoois acetilênicos
The synthesis of chiral acetylenic regioisomers was described by using an appropriate intermediate such as isopropylidene glycerol, a synthon widely used in the enantioselective syntheses. This intermediate was prepared from D-mannitol. The nine obtained compounds have been characterized by their respective spectral data. The mixture of chiral acetylenic alc

20. Monitoramento da microbiota e dos parâmetros físico-químicos em vinhoto / Monitoring of microbiota and physicochemical parameters in vinasse
The agro-industrial activities are responsible for generating large amounts of liquid waste. In the production of cachaça, the production of vinasse is about 4 times higher than the production of the spirit. Usually, tanks for deposition of vinasse are constructed by the producers to receive the residue from the manufacturing process. The main aim of this w

21. Análise da prevalência e perfil de suscetibilidade das espécies de Candida isoladas de hemoculturas em 2006 no Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo / Pevalence and suscetibility profile of Candida species isolated from blood culture in 2006 at Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo
INTRODUCTION: Although the spectrum of fungi causing bloodstream infections continues to expand, Candida species remain responsible for the majority of cases, causing significant morbidity and mortality. The introduction of new antifungal agents in the clinical practice has increased the need for new studies for monitoring changes in the epidemiology and sus

22. Study of the pneumococcal pneumonia of the childrens hospitalized in the pediatrics ward at the University Hospital of the University of São Paulo / Estudo das pneumonias causadas por Streptococcus pneumoniae em crianças internadas na enfermaria de pediatria do Hospital Universitário da Universidade de São Paulo
Introduction: Currently, the annual incidence of the acquired pneumonia in the developing country communities are around 150.7 million cases, among childrens under 5 years of age, and 11 to 20 million (7-13%) of those require hospitalization due to their gravity. In general, the treatments used to be empirical, however, it is important to be noted that Strep

23. Caracterização da comunidade bacteriana em água subterrânea contaminada com tetracloroeteno / Characterization of the bacterial community in groundwater contaminated with tetrachloroethene
Tetrachloroethene (PCE) is one of the most important contaminants of groundwater, since it is highly toxic and potentially carcinogenic. The bacterial communities of PCE contaminated groundwater and the diversity of bacteria capable of degrading this contaminant are barely known. The objective of this work is to compare the structure of bacterial communities

The objective of this research was to carry out a microbiological survey of Brazilian cream cheese ?Requeijão? ( pH 5,8 ), production line and to evaluate its shelf life, in relation to contamination by sporeformers and pathogens such as L. monocytogenes, coagulase positive S. aureus and Coliforms ( 45°C) and to determinate the microorganism(s), surviving
