Application of laccase-based systems for biobleaching and functionalization of sisal fibres
Aracri, Elisabetta (Universitat Politècnica de Catalunya, 2012-01-27)
Tesi
Accés obertThis research project originated from interest in assessing the potential of enzyme technology (particularly laccase-based systems) for the biomodification of sisal specialty fibres by using environmentally friendly ... -
Biografting of ferulic acid onto lignocellulosic fibers by the use of laccases
Rencoret, Jorge; Aracri, Elisabetta; Gutíerrez, Ana; del Rio Andrade, José Carlos; Torres López, Antonio Luis; Vidal Lluciá, Teresa; Martínez, Ángel T. (2014)
Comunicació de congrés
Accés restringit per política de l'editorialLaccases can functionalize paper pulps with phenolic compounds but little is known about the formed linkages. Treatment of a high-kappa sisal pulp with Trametes villosa laccase and ferulic acid resulted in strong increases ... -

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)
Text en actes de congrés
Accés restringit per política de l'editorialThe 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 (NFC) as a potential reinforcement for high performance cement mortar composites
Ardanuy Raso, Mònica; Claramunt Blanes, Josep; Arévalo Peces, Raquel; Parés Sabatés, Ferran; Aracri, Elisabetta; Vidal Lluciá, Teresa (2012-07-09)
Article
Accés obertIn this work, nanofibrillated cellulose (NFC) has been evaluated as a potential reinforcement for cement mortar composites. Two types of vegetable fibres with different composition and properties (cellulose content and ... -
Nanofibrillated cellulose as reinforcement for high performance cement mortar composites
Ardanuy Raso, Mònica; Claramunt Blanes, Josep; Parés Sabatés, Ferran; Aracri, Elisabetta; Vidal Lluciá, Teresa (2012)
Text en actes de congrés
Accés restringit per política de l'editorialIn 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 ... -
Structural insights on laccase biografting of ferulic acid onto lignocellulosic fibers
Rencoret, Jorge; Aracri, Elisabetta; Gutíerrez, Ana; del Río, José C.; Torres López, Antonio Luis; Vidal Lluciá, Teresa; Martínez, Ángel T. (2014-05-15)
Article
Accés restringit per política de l'editorialTreatment of high-kappa sisal pulp with Trametes villosa laccase and ferulic acid resulted in strong increases of kappa-number and acid-group content due to biografting of this phenolic acid, as shown by pyrolysis in the ... -
Use of cyclic voltammetry as an effective tool for selecting effcient enhancers for oxidative bioprocesses: importance of pH
Aracri, Elisabetta; Tzanov, Tzanko; Vidal Lluciá, Teresa (American Chemical Society (ACS), 2013-01-04)
Article
Accés restringit per política de l'editorialSeven natural phenols and two synthetic compounds were evaluated by means of cyclic voltammetry as enhancers for the oxidation of the lignin model compound veratryl alcohol (VAl) and a sulfonated lignin (SL). Their ... -

Xylanase- and laccase-aided hexenuronic acids and lignin removal from specialty sisal fibres
Aracri, Elisabetta; Vidal Lluciá, Teresa (2011)
Article
Accés restringit per política de l'editorialThis work was conceived to investigate for the first time the effectiveness of the combined use of xylanase and laccase for the removal of hexenuronic acids (HexA) and lignin from sisal pulp fibres. To this end, xylanase ...
