  • Laccase-mediated coupling of nonpolar chains for the hydrophobization of lignocellulose 

    García Ubasart, Jordi; Vidal Lluciá, Teresa; Torres López, Antonio Luis; Rojas, Orlando J. (2013-04-09)
    Article
    Accés restringit per política de l'editorial
    We investigate the use of laccase enzymes to couple short nonpolar chains containing aromatic groups onto flax fibers and nanofibrillated cellulose (NFC) with different lignin contents. Trametes villosa, Pycnoporus ...
  • Biomodification of cellulose flax fibers by a new cellulase 

    García Ubasart, Jordi; Torres López, Antonio Luis; Vila, Carlos; Pastor, Francisco J.; Vidal Lluciá, Teresa (2013-01)
    Article
    Accés restringit per política de l'editorial
    The potential of the new cellulase Cel9B from Paenibacillus barcinonensis for the modification of cellulose flax fibers was for the first time assessed in this work. Cel9B treatments were found to enhance the development ...
  • Effect of commercial xylanases applied at extreme conditions in a eucalyptus pulp mill 

    Fillat, Úrsula; Roncero Vivero, María Blanca; Bassa, Alexandre; Sacón, Vera Maria (2012-10)
    Article
    Accés restringit per política de l'editorial
    In this study, we examined the effect of treating eucalyptus pulp with various commercial xylanases to identify the most effective enzyme for use under the industrial bleaching conditions used at the Jacareí mill of the ...
  • Laccase for biobleaching of eucalypt kraft pulp by means of a modified industrial bleaching sequence 

    Moldes, Diego; Vidal Lluciá, Teresa (2012-09)
    Article
    Accés restringit per política de l'editorial
    Biobleaching of kraft pulp is a possible application of laccase, but it has not been described in detail for complete industrial bleaching sequences yet. Therefore, in this work, the biobleaching of Eucalyptus globulus ...
  • Effect of residual lignin and heteropolysaccharides in nanofibrillar cellulose and nanopaper from wood fibers 

    Ferrer Carrera, Ana; Quintana, Elisabet; Filpponen, Ilari; Solala, Iina; Vidal Lluciá, Teresa; Rodríguez Pascual, Alejandro; Laine, Janne; Rojas, Orlando J. (2012-12)
    Article
    Accés restringit per política de l'editorial
    Unbleached (UN), oxygen-delignified and fully-bleached (FB) birch fibers with a residual lignin content of ca. 3, 2 and\1 %, respectively, were used to produce nanofibrillated cellulose (NFC) and nanopaper by using an ...
  • A new approach to the internal sizing of paper via biotechnological processes 

    García Ubasart, Jordi; Roncero Vivero, María Blanca; Vidal Lluciá, Teresa (2011)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This work deals with the study of a new biotechnological procedure, employing laccase in combination with hydrophobic compounds, for the biomodification of fibres and the internal sizing of paper. Cellulose fibres from ...
  • Effect of the laccase mediator system on the fibre properties of TCF bleached kraft pulp 

    Cadena Chamorro, Edith Marleny; Cusola Aumedes, Oriol; Vidal Lluciá, Teresa; Torres López, Antonio Luis (2011)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The application of the laccase mediator system (L stage) to TCF bleached pulp from Eucalyptus globulus with a low residual lignin content provides useful information about its effect in the hexenuronic acids content, ...
  • Cyclodextrin functionalization of several cellulosic substrates for prolonged release of antibacterial agents 

    Cusola Aumedes, Oriol; Tabary, Nicolas; Naceur Belgacem, Mohamed; Bras, Julien (Wiley InterScience, 2012-11-13)
    Article
    Accés restringit per política de l'editorial
    Several cellulosic substrates have been surface-functionalized with cyclomaltoheptaose (b-cyclodextrin, b-CD) using citric acid as a crosslinker agent to obtain new surface-modified materials able to release antiseptic ...
  • Application of surface enzyme treatments using laccase and a hydrophobic compound to paper-based media 

    Cusola Aumedes, Oriol; Valls Vidal, Cristina; Vidal Lluciá, Teresa; Roncero Vivero, María Blanca (2013-01-11)
    Article
    Accés restringit per política de l'editorial
    A new approach for the hydrophobization of finished cellulosic substrates based on a previously reported enzymatic technique is proposed. Commercial finished paper was hydrophobized by using laccase from Trametes villosa ...
  • Laccase from Pycnoporus cinnabarinus and phenolic compounds: can the efficiency of an enzyme mediator for delignifying kenaf pulp be predicted? 

    Andreu Terrén, Glòria; Vidal Lluciá, Teresa (2012-03)
    Article
    Accés restringit per política de l'editorial
    In this work, kenaf pulp was delignified by using laccase in combination with various redox mediators and the efficiency of the different laccase–mediator systems assessed in terms of the changes in pulp properties after ...
