1. Alterações de linguagem na fase moderada da demência na doença de Alzheimer
RESUMO Introdução: Durante o estágio moderado da demência na doença de Alzheimer (DA), o distúrbio de linguagem se intensifica, afetando a comunicação. A identificação minuciosa das habilidades linguísticas mais comprometidas nessa fase da doença pode auxiliar no uso de estratégias facilitadoras para a comunicação. Este estudo visou identifi

2. Highly Solvent Tolerance in Serratia marcescens IBBPo15
ABSTRACT The aim of this study was to investigate the solvent tolerance mechanisms in Serratia marcescens strain IBBPo15 (KT315653). Serratia marcescens IBBPo15 exhibited remarkable solvent-tolerance, being able to survive in the presence of high concentrations (above 40%) of toxic organic solvents, such as cyclohexane, n-hexane, n-decane, toluene, styrene,

3. Evaluation of bacterial diversity recovered from petroleum samples using different physical matrices
ABSTRACT Unraveling the microbial diversity and its complexity in petroleum reservoir environments has been a challenge throughout the years. Despite the techniques developed in order to improve methodologies involving DNA extraction from crude oil, microbial enrichments using different culture conditions can be applied as a way to increase the recovery of D

4. Rhizobial characterization in revegetated areas after bauxite mining
Abstract Little is known regarding how the increased diversity of nitrogen-fixing bacteria contributes to the productivity and diversity of plants in complex communities. However, some authors have shown that the presence of a diverse group of nodulating bacteria is required for different plant species to coexist. A better understanding of the plant symbioti

5. Molecular characterization of lactobacilli isolated from fermented idli batter
Lactic acid bacteria are non pathogenic organism widely distributed in nature typically involved in a large number of spontaneous food fermentation. The purpose of this study was to characterize the bacteriocinogenic lactobacilli from fermented idli batter which can find application in biopreservation and biomedicine. Eight most promising lactobacilli were c

6. Ardra profiles of bacteria and archaea in mangrove sediments with different levels of contamination in the estuarine complex of Paranaguá, Brazil
The mangrove's sediments from the coastal areas under human activities may contain significant contaminations by hydrocarbons, even when there are no visual evidences of it. The microorganisms are essential to these ecosystems, especially in the control of their chemical environment. Sediment samples were collected in two regions under different environment

7. Molecular identification of Lactobacillus spp. associated with puba, a Brazilian fermented cassava food
Puba or carimã is a Brazilian staple food obtained by spontaneous submerged fermentation of cassava roots. A total of 116 lactobacilli and three cocci isolates from 20 commercial puba samples were recovered on de Man, Rogosa and Sharpe agar (MRS); they were characterized for their antagonistic activity against foodborne pathogens and identified taxonomicall

8. Endophytic bacterial diversity in banana 'Prata Anã' (Musa spp.) roots
The genetic diversity of endophytic bacteria in banana 'Prata Anã' roots was characterized. Two hundred and one endophytic bacteria were isolated, 151 of which were classified as Gram-positive and 50 as Gram-negative. No hypersensitivity response was observed in any of the isolates. The rep-PCR technique generated different molecular profiles for each prime

9. Potential use of molecular-typing methods for the identification and characterization of salmonella enterica serotypes isolated in the poultry production chain
Salmonella is widespread in nature and can be found in all links of the poultry production chain. Due to its high impact on meat processing, techniques for the rapid detection and reproducible characterization of Salmonella serotypes in foods are needed. The present study investigated the potential of molecular profiling to identify and differentiate 15 Salm

10. Characterization of immobilized biomass by amplified rDNA restriction analysis (ARDRA) in an anaerobic sequencing-batch biofilm reactor (ASBBR) for the treatment of industrial wastewater
The performance of an anaerobic sequencing-batch biofilm reactor (ASBBR- laboratory scale- 14L )containing biomass immobilized on coal was evaluated for the removal of elevated concentrations of sulfate (between 200 and 3,000 mg SO4-2·L-1) from industrial wastewater effluents. The ASBBR was shown to be efficient for removal of organic material (between 90%

11. Genetic diversity of Rhizobia isolates from Amazon soils using cowpea (Vigna unguiculata) as trap plant
The aim of this work was to characterize rhizobia isolated from the root nodules of cowpea (Vigna unguiculata) plants cultivated in Amazon soils samples by means of ARDRA (Amplified rDNA Restriction Analysis) and sequencing analysis, to know their phylogenetic relationships. The 16S rRNA gene of rhizobia was amplified by PCR (polymerase chain reaction) using

12. Viabilidade de Staphylococcus aureus FRI S-6 e produção de SEB em queijo elaborado com adição de Lactobacillus rhamnosus e Lactococcus lactis
Staphylococcus aureus foi inoculado em queijos produzidos de forma estéril em laboratório, juntamente com Lactobacillus rhamnosus e Lactococcus lactis, isolados de queijo de coalho artesanal e identificados por PCR-ARDRA16S-23S. L. lactis foi capaz de reduzir a contagem de S. aureus no primeiro dia após produção (P<0,05) dos queijos de 3,3x10(7)UFC/g pa
