    • Assessing the enzymatic effects of cellulases and LPMO in improving mechanical fibrillation of cotton linters 

      Valls Vidal, Cristina; Pastor Blasco, Francisco Ignacio Javier; Roncero Vivero, María Blanca; Vidal Lluciá, Teresa; Diaz Lucea, M. Pilar; Martinez Soler, Josefina; Valenzuela, Susana V. (2019-06-26)
      Article
      Open Access
      Background: The increasing interest in replacing petroleum-based products by more sustainable materials in the packaging sector gives relevance to cellulose as a biodegradable natural resource. Moreover, its properties can ...

    • Bacterial cellulose for increasing barrier properties of paper products 

      Fillat Latorre, Amanda; Martinez, Josefina; Valls Vidal, Cristina; Cusola Aumedes, Oriol; Roncero Vivero, María Blanca; Vidal Lluciá, Teresa; Valenzuela, Susana V.; Diaz Lucea, M. Pilar; Pastor Blasco, Francisco Ignacio Javier (2018-08-07)
      Article
      Open Access
      Bacterial cellulose was combined with wood cellulose papers in order to obtain biomaterials with increased barrier properties. For this purpose, different parameters were assessed: two producing bacterial strains ...

    • Bacterial cellulose matrices to develop enzymatically active paper 

      Buruaga Ramiro, Carolina; Valenzuela, Susana V.; Valls Vidal, Cristina; Roncero Vivero, María Blanca; Javier Pastor, F.I.; Diaz Lucea, M. Pilar; Martínez Martínez, Josefina (2020-01-31)
      Article
      Open Access
      This work studies the suitability of bacterial cellulose (BC) matrices to prepare enzymatically active nanocomposites, in a framework of more environmentally friendly methodologies. After BC production and purification, ...

    • Bacterial cellulose-chitosan paper with antimicrobial and antioxidant activities 

      Cabañas Romero, L. Verónica; Valls Vidal, Cristina; Valenzuela, Susana V.; Roncero Vivero, María Blanca; Javier Pastor, F.I.; Diaz Lucea, M. Pilar; Martínez Martínez, Josefina (2020-03-12)
      Article
      Open Access
      The production of paper-based bacterial cellulose-chitosan (BC-Ch) nanocomposites was accomplished following two different approaches. In the first, BC paper sheets were produced and then immersed in an aqueous solution ...

    • Development of an antimicrobial bioactive paper made from bacterial cellulose 

      Buruaga Ramiro, Carolina; Valenzuela, Susana V.; Valls Vidal, Cristina; Roncero Vivero, María Blanca; Javier Pastor, F.I.; Diaz Lucea, M. Pilar; Martinez Soler, Josefina (2020-09-01)
      Article
      Open Access
      Bacterial cellulose (BC) has emerged as an attractive adsorptive material for antimicrobial agents due to its fine network structure, its large surface area, and its high porosity. In the present study, BC paper was first ...

    • Differential activity of lytic polysaccharide monooxygenases on celluloses of different crystallinity. Effectiveness in the sustainable production of cellulose nanofibrils 

      Valenzuela, Susana V.; Valls Vidal, Cristina; Schink, Viviane; Sanchez, Daniel; Roncero Vivero, María Blanca; Diaz Lucea, M. Pilar; Martinez, Josefina; Javier Pastor, F.I. (2019-03-01)
      Article
      Open Access
      A series of cellulosic substrates has been produced, treated with lytic polysaccharide monooxygenase (LPMO) from Streptomyces ambofaciens (SamLPMO10C), and analyzed by high performance anion exchange chromatography (HPAEC) ...

    • Laccase/TEMPO-mediated bacterial cellulose functionalization: production of paper-silver nanoparticles composite with antimicrobial activity 

      Morena Gatius, Ángela Gala; Roncero Vivero, María Blanca; Valenzuela, Susana V.; Valls Vidal, Cristina; Vidal Lluciá, Teresa; Javier Pastor, F.I.; Diaz Lucea, M. Pilar; Martínez Martínez, Josefina (2019-01-01)
      Article
      Open Access
      Bacterial cellulose (BC) was functionalized applying the Laccase/TEMPO oxidative treatment, leading to a five-fold increase of the concentration of carboxyl groups. Paper produced with this cellulose showed improved ...

    • Removal of lignin and hexenuronic acids from sisal fibers with novel xylanases belonging to different GH families
