    An extracellular xylanase was found to be the major protein in the filtrate culture of Penicillium expansum when grown on 0.3 % wheat bran, which showed no xylanase multiplicity. The enzime was partial purified by.ammonium ...
  • Pereira, Jorge F.; Ignacchiti, Mariana D. C.; Araújo, Elza F.; Brommonschenkel, Sérgio H.; Cascardo, Júlio C. M.; Pereira, Gonçalo A. G.; Queiroz, Marisa V. (Fitopatologia Brasileira, 2007-09)
    Reverse transcriptase (RT) sequence analysis is an important technique used to detect the presence of transposable elements in a genome. Putative RT sequences were analyzed in the genome of the pathogenic fungus C. perniciosa, ...
  • Lima, Juliana Oliveira; Pereira, Jorge Fernando; Araújo, Elza Fernandes de; Queiroz, Marisa Vieira de (Brazilian Journal of Microbiology, 2017-02-09)
    Expression of pectinolytic genes is regulated by catabolic repression limiting the production of pectin lyase (PL) if the natural inducer, pectin, is missing from the growth medium. Here, we report the isolation of Penicillium ...
  • Teixeira, Janaina Aparecida; Queiroz, Marisa Vieira de; Araújo, Elza Fernandes de; Cardoso, Patrícia Gomes (Canadian Journal of Microbiology, 2010)
    Recombinant Penicillium griseoroseum strain 105 overproduces an extracellular pectin lyase (PL) under the transcriptional control of the strong gpdA promoter of Aspergillus nidulans. Our aim was to evaluate PL production ...

    The ability of pathogens to survive cheese ripening is a food-security concern. Therefore, this study aimed to evaluate the performance of two alternative methods of analysis of Listeria during the ripening of artisanal ...
  • Ramos, Alessandro C.; Lima, Pedro T.; Dias, Pedro N.; Kasuya, Maria Catarina M.; Feijó, José A. (New Phytologist, 2009-01)
    Mycorrhization is a typical example of a host–pathogen symbiotic interaction where the pathogen cell biology and the host immune response coevolved several functional links. Here, the role played by ion fluxes across the ...
  • Costa, Daniela A.; Souza, Carlos J. A. de; Costa, Patrícia S.; Rodrigues, Marina Q. R. B.; Santos, Ancély F. dos; Lopes, Mariana R.; Genier, Hugo L. A.; Silveira, Wendel B.; Fietto, Luciano G. (Applied Microbiology and Biotechnology, 2014-02-18)
    The conversion of lignocellulose into fermentable sugars is considered a promising alternative for increasing ethanol production. Higher fermentation yield has been achieved through the process of simultaneous saccharification ...
  • Tótola, Marcos R.; Ferreira, Adão S.; Borges, Arnaldo C. (Journal of Thermal Biology, 2007-01)
    The trehalose cycle in filamentous fungi has been suggested to be an important mechanism of tolerance against adverse stress conditions, particularly in thermal stress. Here, we demonstrate that trehalose and trehalase ...
  • Carvalho, Antônio Fernandes de; Perrone, Ítalo Tuler; Silveira, Arlan Caldas Pereira; Fromont, Laurent; Méjean, Serge; Tanguy, Gaëlle; Jeantet, Romain; Schuck, Pierre (Dairy Science & Technology, 2013-07)
    As evaporation is an energy-intensive process, it is important that evaporators operate efficiently at their maximum capacity. The aim of this study was to compare the effectiveness of a pilot-scale, single-stage falling-film ...
  • Merino, Raúl A. Ortiz; Varela, Javier A.; Coughlan, Aisling Y.; Hoshida, Hisashi; Silveira, Wendel B. da; Wilde, Caroline; Kuijpers, Niels G. A.; Geertman, Jan Maarten; Wolfe, Kenneth H.; Morrissey, John P. (Frontiers in Genetics, 2018-03-05)
    Kluyveromyces marxianus is traditionally associated with fermented dairy products, but can also be isolated from diverse non-dairy environments. Because of thermotolerance, rapid growth and other traits, many different ...
  • Gomes, Eliane A.; Kasuya, Maria Catarina M.; Barros, Everaldo G. de; Borges, Arnaldo C.; Araújo, Elza F. (Genetics and Molecular Biology, 2002)
    Inter- and intraspecific variation among 26 isolates of ectomycorrhizal fungi belonging to 8 genera and 19 species were evaluated by analysis of the internal transcribed sequence (ITS) of the rDNA region using restriction ...
  • Pereira, S.C.L.; Vanetti, M.C.D. (Brazilian Journal of Medical and Biological Research, 2015-04-15)
    We aimed to evaluate the potential virulence of Klebsiellaisolates from enteral diets in hospitals, to support nosocomial infection control measures, especially among critical-care patients. Phenotypic determination of ...
  • Coelho, Irene da Silva; Queiroz, Marisa Vieira de; Costa, Maurício Dutra; Kasuya, Maria Catarina Megumi; Araújo, Elza Fernandes de (Brazilian Archives of Biology and Technology, 2010-01)
    The aim of this work was to study the standardization of conditions to obtain and regenerate Epulorhiza repens and Ceratorhiza sp. protoplasts. For E. repens, the largest number of protoplasts (8.0 × 106 protoplasts/mL) ...
  • Dias, E. S.; Araújo, E. F.; Guimarães, W. V.; Muchovej, R. M. C. (World Journal of Microbiology and Biotechnology, 1996-04-11)
    Experiments were performed with the mycorrhizal fungus Suillus granulatus to define the parameters for production and regeneration of protoplasts. Protoplasts were released at frequencies between 1 and 3×107/ml from mycelium ...
