1. Quality of high-protein diet bar plus chia (Salvia hispanica L.) grain evaluated sensorially by untrained tasters
Abstract The objective of this study was to develop, analyze composition and evaluate the microbiological and sensory characteristics of high-protein diet bars (PB) with the addition of chia grain (Salvia hispanica L.), partially replacing isolated soy protein and concentrated whey protein, in proportions of 0, 10, 15 and 20%. The proximate composition was

2. Enterococcus spp. Resistant to Multiple Antimicrobial Drugs and Determination of Fecal Contamination Levels in Mangrove Oysters (Crassostrea rhizophorae)
ABSTRACT The aim of this study was to determine and compare the Most Probable Number (MPN) of Total Coliforms (TC), Escherichia coli and Enterococcus spp. and to characterize the antimicrobial resistance profiles of Enterococcus spp. isolated from oysters collected in the Barra de Guaratiba Mangrove, Rio de Janeiro, Brazil. The enumeration of E. coli has bee

3. Interaction between Thermotolerant Coliforms and Rhizobacteria in Soil Fertilized with Treated Domestic Wastewater
ABSTRACT Studies on the survival of pathogenic microorganisms in the soil after use of wastewater for fertilization of agricultural crops report the effects of moisture, pH, organic matter, and soil temperature on microorganisms. There are few studies that assess the survival of these microorganisms in the rhizosphere of plants fertilized with wastewater. Th

4. Assessing the sources of high fecal coliform levels at an urban tropical beach
Recreational water quality is commonly assessed by microbial indicators such as fecal coliforms. Maceió is the capital of Alagoas state, located in tropical northeastern Brazil. Its beaches are considered as the most beautiful urban beaches in the country. Jatiúca Beach in Maceió was found to be unsuitable for bathing continuously during the year of 2011.

5. Composting sewage sludge with green waste from tree pruning
Sewage sludge (SS) has been widely used as organic fertilizer. However, its continuous use can cause imbalances in soil fertility as well as soil-water-plant system contamination. The study aimed to evaluate possible improvements in the chemical and microbiological characteristics of domestic SS, with low heavy metal contents and pathogens, through the compo

6. Enterobacteria identification and detection of diarrheagenic Escherichia coli in a Port Complex
The Port Complex of Maranhão (PCM) is the second largest port complex in Brazil, receiving ships with large volumes of ballast water. To evaluate the microbiological quality of its waters, physicochemical parameters (pH and salinity), the number of coliforms (thermotolerants and totals), and the presence of enterobacterias and diarrheagenic Escherichia coli

7. The influence of ripening period length and season on the microbiological parameters of a traditional Brazilian cheese
The ripening process of Serro Minas cheese, one of the most popular cheeses produced with raw milk in Brazil, was studied over the course of 60 days of ripening during dry and rainy seasons. Brazilian legislation prohibits the production of cheese from raw milk unless it was submitted to a maturation period greater than 60 days. However Minas Serro cheese is

8. Yeasts and hygienic-sanitary microbial indicators in water buffalo mozzarella produced and commercialized in Minas Gerais, Brazil
The aim of this work was to study the yeast populations and the main hygienic-sanitary microbial indicators in water buffalo mozzarella produced and commercialized in Minas Gerais, Brazil. Forty-two water buffalo mozzarella samples were purchased from retail outlets in Belo Horizonte. In addition, five samples of consecutive starter cultures, curd before aci

9. Fecal indicators and bacterial pathogens in bottled water from Dhaka, Bangladesh
Forty-six bottled water samples representing 16 brands from Dhaka, Bangladesh were tested for the numbers of total coliforms, fecal indicator bacteria (i.e., thermotolerant Escherichia coli and Enterococcus spp.) and potential bacterial pathogens (i.e., Aeromonas hydrophil, Pseudomonas aeruginos, Salmonella spp., and Shigella spp.). Among the 16 brands teste

10. Efecto del secado térmico y el tratamiento alcalino en las características microbiológicas y químicas de biosólidos de plantas de tratamiento de aguas residuales domésticas
We evaluated the effect of thermal drying (60 to 75 ºC and times from 0 to 12.58 h) and alkaline treatment (Ca(OH)2 and CaO at doses from 8 to 10%.) on the microbiological and chemical characteristics of biosolids from the Cañaveralejo WWTP. The results showed that in thermal drying all temperatures studied were sufficient to achieve the sanitation of bios

11. Comunidade fitoplanctônica no monitoramento de rios do estado de São Paulo / Phytoplankton community in monitoring rivers of São Paulo state
There are few studies conducted on phytoplankton inhabiting the rivers. In São Paulo State many of the abstraction of water for public supply are located in lowland rivers and streams of low gradient and have a lot of dam built in their courses, and the presence of lateral lakes and small dams to capture water, contributing to the development of planktonic

12. Águas pluviais para usos não potáveis em escolas municipais: estudo de caso na região da baixada de Jacarepaguá, RJ. / Rainwater for non potable uses in municipal schools: study of case in the region of Baixada de Jacarepaguá- RJ.
Rainwater harvesting does not constitute a new strategy or technology. However, recently it has been proposed in well-developed regions or in development (peri-urban) in response to long periods of dryness, increased demand for water, greater public awareness of urban flooding and its genesis, and increased interest in sustainable construction practices, inc
