  • A new approach to the internal sizing of paper via biotechnological processes 

    García Ubasart, Jordi; Roncero Vivero, María Blanca; Vidal Lluciá, Teresa (2011)
    Conference report
    Restricted access - publisher's policy
    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)
    Conference report
    Restricted access - publisher's policy
    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, ...
  • Bleached dissolving pulps applying laccase treatments 

    Quintana, Elisabet; Valls Vidal, Cristina; Roncero Vivero, María Blanca (2012)
    Conference report
    Restricted access - publisher's policy
    A biobleaching sequence, using a laccase enzyme (Trametes Villosa) in combination with different mediators, was applied to softwood dissolving cellulose in order to study its bleaching efficiency and its potential in terms ...
  • Laccase-TEMPO oxidation of sisal pulp for improving paper strength properties: influence of the operating conditions 

    Aracri, Elisabetta; Valls Vidal, Cristina; Vidal Lluciá, Teresa (2011)
    Conference report
    Restricted access - publisher's policy
    The oxidation of a low lignin content sisal pulp by laccase-TEMPO system has been investigated and evaluated as potential approach for improving the paper strength properties. TEMPO mediated oxidation was found to cause ...
