    • A novel enzymatic approach to nanocrystalline cellulose preparation 

      Beltramino, Facundo; Roncero Vivero, María Blanca; Vidal Lluciá, Teresa; Valls Vidal, Cristina (2018-06-01)
      Article
      Accés obert
      In this work, conditions for an enzymatic pretreatment prior to NCC isolation from cotton linter were assessed. Different cellulase doses and reaction times were studied within an experimental design and NCC were obtained. ...

    • 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
      Accés obert
      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 ...

    • Endoglucanase treatments for improving pulp reactivity in biobleached and commercial dissolving pulps 

      Quintana, Elisabet; Valls Vidal, Cristina; Vidal Lluciá, Teresa; Roncero Vivero, María Blanca (2015)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      In this study, a bleached commercial dissolving pulp and a TCF sulphite pulp, bleached at the laboratory scale with a laccase–violuric acid system and complemented with a pressurized hydrogen peroxide stage (LVAPO), were ...

    • Increasing yield of nanocrystalline cellulose preparation process by a cellulase pretreatment 

      Beltramino Heffes, Facundo; Roncero Vivero, María Blanca; Vidal Lluciá, Teresa; Torres López, Antonio Luis; Valls Vidal, Cristina (2015-06-09)
      Article
      Accés obert
      In this work the introduction of a cellulase treatment prior to NCC isolation was assessed. NCC was produced using sulfuric acid at two different concentrations (62 and 64% wt.). The effect of pore size for filtration step ...

    • Optimization of sulfuric acid hydrolysis conditions for preparation of nanocrystalline cellulose from enzymatically pretreated fibers 

      Beltramino Heffes, Facundo; Roncero Vivero, María Blanca; Torres López, Antonio Luis; Vidal Lluciá, Teresa; Valls Vidal, Cristina (2016-03-22)
      Article
      Accés obert
      NCC preparation using sulfuric acid hydrolysis from cellulase pretreated fibers was optimized in order to obtain the highest possible yield with 62% and 65% wt. sulfuric acid throughout two statistical plans. At optimal ...
