1. Microbial diversity of soils on the banks of the Solimões and Negro rivers, state of Amazonas, Brazil
Analysis of bacterial diversity in soils along the banks of the Solimões and Negro rivers, state of Amazonas, Brazil, was by partial sequencing of the genes codifying the rDNA16S region. Diversity of operational taxonomic units (OTU) and of the divergent sequences obtained were applied in comparative analysis of microbiological diversity in the two environm

2. Desenvolvimento e avaliação de protocolos para descontaminação de explantes de mangueira visando à micropropagação.
RESUMO: A eliminação de microrganismos é uma condição essencial para o estabelecimento de um processo de regeneração in vitro, pois eles além de competirem pelos nutrientes também produzem toxinas que causam a morte do explante. O trabalho visou desenvolver metodologias de controle de crescimento de microrganismos provenientes de explantes de mangue

3. AvaliaÃÃo da produÃÃo biotecnolÃgica de 2-feniletanol em resÃduo lÃquido de fecularia
2-phenylethanol is the most used fragrance in the food, cosmetics and fragrance industry. It is mainly produced by chemical process, but with many impurities. The biotechnological process of production is feasible and is being studied with various microrganisms, among them, Geotrichum fragrans, Saccharomyces cerevisiae and Kluyveromyces marxianus. The use of

4. Análise da produção do antitumoral retamicina em cultivos contínuos de Streptomyces olindensis ICB20 utilizando planejamento fatorial. / Analysis of the production of the antitumor drug retamycin in continous cultures of Streptomyces olindensis ICB 20 using factorial desing.
The aim of this project was to study the production of retamycin in bench-top bioreactors by Streptomyces olindensis ICB20 in continuous cultures in order to evaluate the influence of the agitation rate (N=300, 500 or 700 rpm), the dissolved oxygen concentration (20%, 50% or 80%) and the specific growth rate (µ=0.05, 0.15 or 0.25 h-¹). A full factorial exp

5. Avaliação da eficácia da esterização de furadeiras elétricas domésticas utilizadas em cirurgias ortopédicas / Evaluation of the efficacy of the sterilization of ordinary electric drills for orthopedic surgeries
Electric drills have been used to perform orthopedic surgeries in Brazilian hospitals for almost more than 50 years. This electric equipment is heat-sensitive and it is not appropriate to use in surgical procedures. Until now the efficacy of sterilization of this item had been not evaluated as a potential risk for the occurrence of surgical site infection or

6. Isolamento e uso de Lactobacillus buchneri na ensilagem de capim-mombaÃa e cana-de-aÃÃcar / Isolation and use of Lactobacillus buchneri in the ensiling of MombaÃa grass and sugar cane
It was aimed by this work to isolate a strain of Lactobacillus buchneri in sugar cane silages for use in the ensiling of tropical forage plants. In addition, it was aimed to evaluate the influence of the species Lactobacillus buchneri on the chemical and microbiologic profile and on the aerobic stability of the silages of sugar cane (Saccharum spp.) and Momb

7. Microbiological study of intrauterine contents and histopathology of uterus of bitches with pyometra and research of virulence factors in E.coli isolates and the potential risk to human health / Estudo microbiológico de conteúdo intra-uterino e histopatológico de útero de cadelas com piometra e pesquisa de fatores de virulência em cepas de E.coli e o potencial risco à saúde humana
Canine pyometra, also known as cystic endometrial hyperplasia complex, is a disease of the adult dog characterized by the inflammation of the uterus with accumulation of purulent discharge, that occurs in the luteus phase of the estrus cycle and that can affect various systems of the organism. It occurs in result of hormone alterations and generally is assoc

8. Efeito pÃs-antibiÃticos de um novo derivado 1,2,4-oxadiazol-hidrazida e suas associaÃÃes frente ao Mycobacterium fortuitum e Mycobacterium smegmatis
The frequent resistance of atypical micobacteria for antituberculous drugs, the absence of efficient therapeutical scheme and the studies about applications of new molecules against micobactÃrias induced us to determinate the postantibiotic effect (PAE) in vitro of a new derivative 1,2,4-oxadiazole-hidrazide (HHBA) and its associations with ofloxacin (OFLO)

9. Rehabilitation potential of a mine spoil trhough revegetation and microbial management. / Potencial de reabilitação do solo de uma área degradada, através da revegetação e do manejo microbiano.
The increasing degraded soil areas caused by open cast mining activities has brought critical damages to the environment. The mine spoil must be ameliorated with anthropogenic interferences, consisting of revegetating soils, introducing organic matter and microbial diversity, basic conditions for a sustainable soil biological activity. The objective of this

10. Isolamento de Mycobacterium bovis em cão
This report describes the isolation of Mycobacterium bovis from a dog with a history of co-habitation with bufallos infected with Mycobacterium bovis. After necropsy, the microrganism was isolated from a mesenteric lymphatic node in Stonebrink media and bacterial identification was confirmed by biochemical tests.

11. Estudo dos efeitos esterilizantes da aplicação de pulsos eletricos de alta voltagem em alimentos liquidos
Non-thermal food pasteurization and sterilization technologies are receiving increasing attention. The advantage is that of sterilizing contaminants in liquid foods without denaturation of some physiological compounds such as proteins and vitamins. In this research, the effects of the shape of the treatment chamber (plate-plate electrodes and coaxial) and in

12. Associação de acido clavulanico a cefalosporinas frente a Staphylococus aureus produtores de beta-lactamase
Since the 40 s decade, with the coming of the clinical chemotherapy, there are already reports of bacterial resistance to drugs. This resistance is preoccupying, since it becomes more and more difficult the treatment certain infections associated to the those microrganisms. Countless attempts take place in the sense of finding new drugs or associations, or s
