Aderência bacteriana in vitro a lentes intra-oculares de polimetilmetacrilato e de silicone
(2004) [Artigo de periódico]Objetivos: Verificar a aderência bacteriana a lentes intra-oculares de silicone e de polimetilmetacrilato como possível fator de risco no desenvolvimento de endoftalmite pós-operatória, utilizando-se um modelo in vitro com ... -
Characterization of bacterial population during composting of municipal solid waste
(2005) [Artigo de periódico]Compostagem é um processo biológico natural de degradação da matéria orgânica, desenvolvida espontaneamente por microrganismos cuja atividade metabólica leva a mineralização e humificação parcial da matéria orgânica. O ... -
Characterization of plant growth-promoting bacteria inhabiting Vrisea gigantea Gaud. and Tillandsia aeranthos (Loiseleur) L. B. Smith (Bromeliaceae)
(2013) [Artigo de periódico]Microorganisms that live inside and around a plant can supply it with essential substances, such as phytohormones and essential nutrients. The present investigation aimed to isolate and characterize the phyllosphere, the ... -
Draft genome sequence of Bacillus sp. strain UFRGS-B20, a hydrocarbon degrader
(2018) [Artigo de periódico]Bacillus sp. strain UFRGS-B20 was isolated in 2012 from Brazilian landfarming soil contaminated with petrochemical oily sludge. This strain was subjected to hydrocarbon biodegradation tests, showing degradation rates of ... -
Isolation and characterization of two plant growth-promoting bacteria from the rhizoplane of a legume (Lupinus albescens) in sandy soil
(2010) [Artigo de periódico]Duas linhagens bacterianas que apresentaram amplificação de parte do gene nifH, RP1p e RP2p, pertencentes aos gêneros Enterobacter e Serratia, foram isoladas do rizoplano de Lupinus albescens. Essas bactérias são Gram-negativas, ... -
Modulation of gene expression by essential oils in bacteria
(2018) [Artigo de periódico]The emerging of drug-resistant strains imposes some new strategies in prevent bacteria spread. It is pivotal to find new candidates for drug development. The essential oils (EOs) extracted from plants are alternatives for ... -
Molecular investigation of isolates from a multistate polymicrobial outbreak associated with contaminated total parenteral nutrition in Brazil
(2018) [Artigo de periódico]Background: Between November 2013 and June 2014, 56 cases of bacteremia (15 deaths) associated with the use of Total Parenteral Nutrition (TPN) and/or calcium gluconate (CG) were reported in four Brazilian states. Methods: ... -
Phylogenetic identification of marine bacteria isolated from deep-sea sediments of the eastern South Atlantic Ocean
(2013) [Artigo de periódico]The deep-sea environments of the South Atlantic Ocean are less studied in comparison to the North Atlantic and Pacific Oceans. With the aim of identifying the deep-sea bacteria in this less known ocean, 70 strains were ... -
Purification and characterization of a thermostable alkaline cellulase produced by Bacillus licheniformis 380 isolated from compost
(2017) [Artigo de periódico]During composting processes, the degradation of organic waste is accomplished and driven by a succession of microbial populations exhibiting a broad range of functional competencies. A total of 183 bacteria, isolated from ... -
Sanitary quality and diversity of culturable bacteria and yeasts in processed and in natura yerba mate (Ilex paraguariensis A. St.-Hil.)
(2015) [Artigo de periódico]Yerba mate (Ilex paraguariensis) is a native plant of southern Brazil, whose leaves, after processing, are used as a beverage by the population of Brazil, Argentina, Paraguay and Uruguay. This study assessed the sanitary ... -
Temporal variation of bacterial population and response to physical and chemical parameters along a petrochemical industry wastewater treatment plant
(2019) [Artigo de periódico]The petrochemical industry has played a considerable role in generation and release of waste in the environment. Activated sludge and facultative lagoons are commonly used for domestic and industrial wastewater treatment ... -
Thermal resistance of proteolytic enzymes produced by psychrotrophic bacteria isolated from buffalo milk
(2017) [Artigo de periódico]Background and Objective: Psychrotrophic bacteria produce extracellular proteases, resulting in deterioration and reduced shelf life of dairy products. In this study, 21 species of psychotropic bacteria isolated from buffalo ...
