25. Quality characteristics of Moroccan sweet paprika (Capsicum annuum L.) at different sampling times
"La Niora" is a red pepper variety cultivated in Tadla Region (Morocco) which is used for manufacturing paprika after sun drying. The paprika quality (nutritional, chemical and microbiological) was evaluated immediately after milling, from September to December. Sampling time mainly affected paprika color and the total capsaicinoid and vitamin C contents. Th

26. 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

27. Inactivation of E. coli and B. subtilis spores in ozonized cassava starch
In the present study, the efficacy of ozone inactivation of B. subtilis spores and E. coli in cassava starch was evaluated. Cassava starch with 18 and 30% moisture content was processed with ozone at concentrations of 40-118 ppm and exposure times of 15-120 minutes. The processing at 113 ppm/120 minutes (maximum exposure level to ozone evaluated) at 18% of m

28. Influence of lingual bracket position on microbial and periodontal parameters in vivo
OBJECTIVE: Lingual orthodontics is becoming more popular in dental practice. The purpose of the present investigation was to compare plaque formation on teeth bonded with the same bracket onto buccal or lingual surface, with non-bonded control teeth, via an in vivo growth experiment over a 30-day period. MATERIAL AND METHODS: A randomized controlled trial wi

29. Microbiological biodiversity in poultry and paddy straw wastes in composting systems
Immense quantity of waste is generated in association with poultry meat egg and crop production. The potential risks due to disposal of these wastes are magnified as a result of dense refinement of poultry production and the decreasing amount of land available for waste disposal. The study aims at studying the microbiological biodiversity of poultry waste an

30. Anaerobic treatment of cellulose bleach plant wastewater: chlorinated organics and genotoxicity removal
This study assessed the removal efficiency of organic matter and how it relates to the decrease of toxic and mutagenic effects when an anaerobic reactor is used to treat the bleaching effluent from two kraft pulp mills. Parameters such as COD (chemical oxygen demand), DOC (dissolved organic carbon), AOX (adsorbable organic halogen), ASL (acid soluble lignin)

31. Biocide activity of microfiber mops with and without silver after contamination
OBJECTIVE: The purpose of the present research was to compare the residual microbial load in Solo System microfiber mops with silver and in normal microfiber mops without silver to see whether those with the silver prevent bacterial proliferation and spread more effectively during normal cleaning operations. METHODS: Mops with and without silver were experim

32. Ocorrência de leite ácido e de resíduos de antimicrobianos no leite cru entregue em laticínios na região do Vale do Taquari, RS, Brasil = Occurrence of acidity and antimicrobial residues in raw milk delivered at a dairy plant in Vale do Taquari, RS, Brazil / Occurrence of acidity and antimicrobial residues in raw milk delivered at a dairy plant in Vale do Taquari, RS, Brazil
Background: Milk is considered one of the most important sources of nutrients. It contains proteins, fat acids, vitamins and minerals. Its activity has a significant socio-economic impact in all over the world and in Brazil. The presence of bacterial inhibitors in milk for human consumption is a great concern for the dairy products industry and public health

33. Action of ultraviolet radiation on the reduction of microbiota from cachaça-producing sugarcane / Ação da radiação ultravioleta na redução da microbiota do caldo de cana para produção de cachaça
The fermentation process for the production of cachaça (the most popular alcoholic distilled beverage) in Brazil is influenced by the quality of the raw material. Thus any raw material containing a high microbial load results in an ineffective fermentation, which is reflected on the final quality of the cachaça. This study evaluated the action of ultraviol

34. Avaliação da comunidade microbiana procarionte através de técnicas moleculares - FISH, PCR/DGGE e sequenciamento em sistemas artificiais de redução de cargas: ênfase ao estudo de lagoa de estabilização facultativa. / Prokariotic microbial community assessment by molecular techniques - FISH, PCR/DGGE and sequencing in load reduction artificial systems - enphasys on the study of facultative stabilization pond.
Microorganisms are amongst the most responsible for the conversion of sewage organic compounds and they are the key of the treatment success. The combination of two or more molecular techniques in this kind of assessment allows getting more accurate results concerning a microbial community. The facultative stabilization pond microbial community structure of

35. Inativação do Mycobacterium bovis (espoligotipo BR024) em creme de leite submetido à alguns parâmetros comerciais de pasteurização / Mycobacterium bovis (spoligotype BR024) inactivation in whipping cream submitted to commercial pasteurization parameters
The thermal resistance of microorganisms is influenced by the agent in question, the initial microbial load and the characteristics of the substrate that can exert a protective effect on the cell, for example, the fat content. The pasteurization of whipping cream aims to eliminate pathogen microorganisms that may occasionally be present in milk. However, the

36. Microbial load of reusables trocars after gynecology laparoscopy / Carga microbiana de trocartes reprocessaveis apos laparoscopias ginecologicas
The transmission of hospital infections is related to survival of microorganisms on environmental surfaces and surgical instruments. In recent years, Brazil has been facing a scenario scattered on the validation of cleaning and sterilizing surgical instruments used in minimally invasive procedures performed primarily for video. For implantation of effective
