13. Bloodstream infection in patients with end-stage renal disease in a teaching hospital in central-western Brazil
Introduction Vascular access in patients undergoing hemodialysis is considered a critical determinant of bloodstream infection (BSI) and is associated with high morbidity and mortality. The purpose of this study was to investigate the occurrence of BSI in patients with end-stage renal disease using central venous catheters for hemodialysis. Methods A coho

14. Isolation of a yeast strain able to produce a polygalacturonase with maceration activity of cassava roots
The objective of the present study was the isolation of a yeast strain, from citrus fruit peels, able to produce a polygalacturonase by submerged fermentation with maceration activity of raw cassava roots. Among 160 yeast strains isolated from citrus peels, one strain exhibited the strongest pectinolytic activity. This yeast was identified as Wickerhamomyces

15. BactÃrias com Potencial BiotecnolÃgico na DescoloraÃÃo de Corantes TÃxteis / Bacteria with biotechnological potential in the discoloration of textile dyes
The discharge of effluents from textile industries for water bodies is currently a major concern for environmentalists as a function of synthetic dyes used to color fabrics thus polluting the environment. Biological treatments, especially with the use of bacteria, present themselves as the most economically viable and widely used to decolorize colored efflue

17. Isolation and purification of complex II from proteus mirabilis strain ATCC 29245
A respiratory complex was isolated from plasma membrane of pathogenic Proteus mirabilis strain ATCC 29245. It was identified as complex II consisting of succinate:quinone oxidoreductase (EC 1.3.5.1) containing single heme b. The complex II was purified by ion-exchange chromatography and gel filtration. The molecular weight of purified complex was 116.5 kDa a

18. Isolation and characterization of a microorganism involved on autotrophic denitrification by sulfide oxidation in a vertical fixed-bed reactor / Isolamento e caracterização de microrganismo envolvido na desnitrificação autrófica pela oxidação de sulfeto em reator vertical de leito fixo
The aim of this study was to evaluate the community involved on autotrophic denitrification by sulfide oxidation applied to the post-treatment of anaerobic effluents. The enrichment of the bacterial community and autotrophic denitrifier community was accessed in three immobilized bed reactors operated at the conditions of autotrophic reduction of nitrate, au

19. Identifying and controlling a multiresistant pseudomonas aeruginosa outbreak in a latin-american cancer centre and its associated risk factors
Pseudomonas aeruginosa is an important and frightening microorganism for patients suffering from cancer. Multiresistant P. aeruginosa (MRPA) may appear as a consequence of exposure to multiple antibiotics or from a breakdown in infection control practices. This article reports an MRPA outbreak in a cancer treatment centre and the consequent case control stud

20. Biodegradação do herbicida mesotrione por linhagens bacterianas isoladas de folhas de milho
Chemical fertilizers and pesticides have become an important part of modern agriculture. The use of these chemical brought great benefits but also created new problems, such as disposal after use, persistence over time and accumulation in the environment, resulting significant bad consequences to public health and adverse impact on ecosystems. Maize culture

21. Listeria monocytogenes em linguiças do tipo frescal vendidas a varejo no município de Salvador-BA e eficácia do bacteriófago P100 no controle da contaminação pelo patógeno.
The outbreaks of Food-borne Diseases are a reason of concern for the food industries and public health organs. Listeria monocytogenes is known as an important pathogen causing diseases transmitted by food and its importance has been growing since the 1980s. Although the number of disease cases per year is relatively low, the infection can be serious, with le

22. Seleção de leveduras potencialmente produtoras de vitaminas do complexo B e estudo do processo fermentativo visando aplicação em alimentação animal / Screening of potential B-vitamin producer yeasts and the study of fermentation process for feed application
The present work had as the main the objective, the isolation and selection of potential B-vitamin producer yeast and the study of fermentative process for B-vitamin production for feed application. Among 267 isolated strains, one was selected as extracellular thiamine producer and the strain Candida sp. LEB 130 as riboflavin and biotin producer. In the stud

23. Técnicas modernas em espectrometria de massas aplicadas no isolamento de bioherbicidas produzidos por microrganismos / Modern Techniques on Mass Spectrometry applied to the isolation of bioherbicides produced by microorganisms
In this work a quick and efficient methodology was employed for the identification of phytotoxic metabolites produced by microorganisms. The isolation of the bioactive compound was guided by Lemna minor bioassay. Mass spectrometry, especially LC-MS, was used to accelerate the process of identification of the phytotoxin. All bacteria were symbiotic to the phy
