A new approach to the internal sizing of paper via biotechnological processes
(2011)
Conference report
Restricted access - publisher's policyThis 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
(2011)
Conference report
Restricted access - publisher's policyThe 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
(2012)
Conference report
Restricted access - publisher's policyA 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
(2011)
Conference report
Restricted access - publisher's policyThe 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 ... -
Nanofibrillated cellulose as reinforcement for high performance cement mortar composites
(2012)
Conference report
Restricted access - publisher's policyIn this work, the preparation and characterization of new cement mortars reinforced with nanofibrillated cellulose fibres has been carried out. The effect of the fibre fibrillation degree on the mechanical performance of ... -
Paper functionalization by means of enzymatic surface treatments using hydrophobic compounds and lignosulfonates
(2012)
Conference report
Restricted access - publisher's policyIn the present work an innovative method for achieving enzymatic surface functionalization on finished paper sheets is presented. A commercial filter paper was surface sized with laccase derived from Trametes Villosa, ... -

Using biotechnology for paper functionalisation: flax fibers with antimicrobial properties
(2010)
Conference lecture
Restricted access - publisher's policyUnbleached flax fibres were treated with laccase from Pycnoporus cinnabarinus and low molecular weight phenols (syringaldehyde –SA, acetosyringone –AS- and p-coumaric acid –PCA-) to biomodify lignocellulosic fibres in order ... -
Enzymatic treatments of paper surface using laccase, hydrophobic compounds and lignin
(2011)
Conference report
Restricted access - publisher's policyThis study demonstrates the potential of applying surface enzymatic treatments on finished paper sheets to improve their physical characteristics. Research studies have recently reported that is possible to internally size ... -
