      Bleached cellulose with good end-properties (_90% ISO brightness and 62% cellulose preservation) was obtained by using a totally chlorine-free biobleaching process (TCF). Unbleached sulphite cellulose was treated with ...

    • Assessing the environmental impact of biobleaching: effects of the operational conditions 

      Valls Vidal, Cristina; Quintana, Elisabet; Roncero Vivero, María Blanca (2012-01)
      Article
      Accés restringit per política de l'editorial
      The environmental impact of enzyme bleaching stages applied to oxygen-delignified eucalypt kraft pulp was assessed via the chemical oxygen demand (COD), color, absorbance spectrum, residual enzyme activity and Microtox ...

    • Assessment of the potential of enzymes to produce dissolving pulps 

      Valls Vidal, Cristina; Quintana, Elisabet; Vidal Lluciá, Teresa; Roncero Vivero, María Blanca (Universidade de Aveiro, 2018)

      Accés restringit per política de l'editorial
      In this work, a totally chlorine free (TCF) sequence including a laccase-mediator system was developed in a softwood sulfite pulp. Then, purification was carried out employing strong alkaline extractions and hydrolytic ...

    • Effectiveness of novel xylanases belonging to different GH families on lignin and hexenuronic acids removal from specialty sisal fibres 

      Valenzuela Mayorga, Susana Valeria; Valls Vidal, Cristina; Roncero Vivero, María Blanca; Vidal Lluciá, Teresa; Díaz Lucea, Pilar; Pastor Blasco, Francisco Ignacio Javier (2014)
      Article
      Accés restringit per política de l'editorial
      Background: The effectiveness of xylanases on lignin removal from pulps differs widely depending on the enzyme family, the type of pulp and the bleaching sequence among other factors. Xylanases can also reduce the presence ...

    • Enzymatically treated sulphite pulp to give dissolving-pulp characteristics 

      Quintana, Elisabet; Valls Vidal, Cristina; Vidal Lluciá, Teresa; Roncero Vivero, María Blanca (2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Bleached cellulose with good end-properties (~90% ISO brightness, < 0.5 kappa number and substantially preserved cellulose integrity) was obtained by using a totally chlorine-free (TCF) biobleaching sequence. The initial ...
