Ethanol stress responses of Kluyveromyces marxianus CCT 7735 revealed by proteo...
Alvim, Mariana Caroline Tocantins; Vital, Camilo Elber; Vieira, Nívea Moreira; Silveira, Fernando Augusto da; Balbino, Thércia RochaKluyveromyces marxianus CCT 7735 offers advantages to ethanol production over Saccharomyces cerevisiae, including thermotolerance and the ability to convert lactose to ethanol. However, its growth is impaired at high ethanol concentrations. Herein we report on the protein and intracellular metabolite profiles of K. marxianus at 1 and 4 h under ethanol exposure. The concentration of some amino acids, trehalose a...
Proteomic analysis of the venom of the predatory ant Pachycondyla striata (Hyme...
Santos, Pollyanna Pereira; Games, Patricia Dias; Azevedo, Dihego Oliveira; Barros, Edvaldo; Oliveira, Leandro Licursi deThe ants use their venom for predation, defense, and communication. The venom of these insects is rich in peptides and proteins, and compared with other animal venoms, ant venoms remain poorly explored. The objective of this study was to evaluate the protein content of the venom in the Ponerinae ant Pachycondyla striata. Venom samples were collected by manual gland reservoir dissection, and samples were submitt...
N-dodecanoyl-homoserine lactone influences the levels of thiol and proteins rel...
Almeida, Felipe Alves de; Carneiro, Deisy Guimarães; Barros, Edvaldo; Pinto, Uelinton Manoel; Oliveira, Leandro Licursi deQuorum sensing is a cell-cell communication mechanism mediated by chemical signals that leads to differential gene expression in response to high population density. Salmonella is unable to synthesize the autoinducer-1 (AI-1), N-acyl homoserine lactone (AHL), but is able to recognize AHLs produced by other microorganisms through SdiA protein. This study aimed to evaluate the fatty acid and protein profiles of S...
Differences in beef quality between Angus (Bos taurus taurus) and Nellore (Bos ...
Rodrigues, Rafael Torres de Souza; Chizzotti, Mario Luiz; Vital, Camilo Elber; Baracat-Pereira, Maria Cristina; Barros, Edvaldo; Busato, Karina CostaProteins are the major constituents of muscle and are key molecules regulating the metabolic changes during conversion of muscle to meat. Brazil is one of the largest exporters of beef and most Brazilian cattle are composed by zebu (Nellore) genotype. Bos indicus beef is generally leaner and tougher than Bos taurus such as Angus. The aim of this study was to compare the muscle proteomic and phosphoproteomic pro...
Análise proteômica de glândulas salivares do carrapato Amblyomma sculptum
Barros, EdvaldoCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; Os carrapatos são artrópodes hematófagos obrigatórios de grande importância médica e veterinária. Estes artrópodes tem desenvolvido adaptações evolutivas que permitem aos mesmos a sobrevivência por longos períodos de tempo sem se alimentarem ou que, após se alimentarem até a ingurgitação, vivam com a presença de altos níveis de substâncias que estimul...
Brazilian spotted fever in Caratinga, Minas Gerais.
Galvão, Márcio Antônio Moreira; Siqueira, Cláudio Lísias Mafra de; Freitas, Renata Nascimento de; Cardoso, Luciane Daniele; Padilha, Amanda de FreitasIntrodução: a Ordem Rickettsiales abriga um grupo de parasitas intracelulares obrigatorios, responsaveis por causar doencas conhecidas como riquetsioses. No Brasil, a riquetsiose mais comum e a febre maculosa brasileira (FMB). Objetivos: determinar o nivel de endemicidade para a FMB no municipio de Caratinga, Minas Gerais, em diferentes momentos epidemiologicos. Métodos: inqueritos epidemiológico e sorologico e...
Infecção por Rickettsia em artrópodes vetores de uma região sob acentuada press...
Barros, EdvaldoThe gender Rickettsia is constituted by alpha-protobacteria gramnegatives, pleomorphics and obligatory intracellular parasites that infect preferentially endothelial cells, transmitted to the vertebrate host through fleas, lices and, mainly, ticks. These microorganisms, thoroughly distributed by the world, are reported infecting ticks of almost whole national territory, however, with high concentration in the s...
