1. Pré-cloração associada à adsorção em carvão ativado em pó e flotação por ar dissolvido na remoção de microcistina presente em três diferentes concentrações em águas provenientes de reservatório eutrofizado / Prechlorination associated to adsorption with powdered activated carbon and dissolved air flotation in the removal of three concentrations of microcystin present in eutroficated reservoir water
The disordered growth of cities, the use of planting areas near the water sources and the launch of domestic and industrial wastewater without treatment are the main sources of water bodiespollution. Such pollution contributes to increase the nutrient loading in the water bodies. In association with climatic factors, this enrichment of nutrient provides suit

2. DESENVOLVIMENTO DE METODOLOGIA ANALITICA POR CROMATOGRAFIA/ESPECTROMETRIA DE MASSAS PARA AVALIAÇÃO DA OCORRÊNCIA DE PERTURBADORES ENDÓCRINOS EM MANANCIAIS DE ABASTECIMENTO DA REGIÃO METROPOLITANA DE BELO HORIZONTE
Some organic molecules classified as endocrine disrupters compounds (EDC) have been found in surface waters and attracted attention from the scientific community due to their hability to tamper with the endocrine system of aquatic fauna, hence due to the potential risk they pose to human health. Among the compunds with endocrine properties, the hormones (17&

3. Remoção de células de Microcystis sp por pré-cloração, coagulação, filtração direta e pós-cloração em escala de bancada / Removal of cells of Microcystis sp by prechlorination, coagulation, direct filtration and poschlorination in jar-test experiment
Por suas características fisiológicas, cianobactérias se adaptam rapidamente em sistemas eutrofizados e geralmente predominam na comunidade fitoplanctônica. O crescimento excessivo desses microrganismos resulta em dificuldades e acréscimo nos custos do tratamento de água para consumo humano. Além da rápida colmatação dos filtros devido à grande ma

4. Potential usefulness of bacteriophages that infect Bacteroides fragilis as model organisms for monitoring virus removal in drinking water treatment plants.
The presence of bacteriophages at different stages in three drinking water treatment plants was evaluated to study the usefulness of phages as model organisms for assessing the efficiency of the processes. The bacteriophages tested were somatic coliphages, F-specific coliphages, and phages infecting Bacteroides fragilis. The presence of enteroviruses and cur

5. A Pilot Study of Bacteriological Population Changes through Potable Water Treatment and Distribution
This pilot study compares the compositions of bacterial biofilms in pipe networks supplied with water containing either high levels of biodegradable organic matter (BOM) or low levels of BOM (conventionally or biologically treated, respectively). The Microbial Identification System for fatty acid analysis was utilized in this study to identify a large number

6. Paleoepidemiologic investigation of Legionnaires disease at Wadsworth Veterans Administration Hospital by using three typing methods for comparison of legionellae from clinical and environmental sources.
Multilocus enzyme electrophoresis, monoclonal antibody typing for Legionella pneumophila serogroup 1, and plasmid analysis were used to type 89 L. pneumophila strains isolated from nosocomial cases of Legionnaires disease at the Veterans Administration Wadsworth Medical Center (VAWMC) and from the hospital environment. Twelve L. pneumophila clinical isolates
