      Two enzyme treatments involving xylanase (X) and laccase (L) were used jointly in an XLE sequence (where E denotes alkaline extraction) to bleach oxygen-delignified eucalyptus kraft pulp in the presence of 1-hydroxybenzotriazol ...

    • Using electrochemical methods to study the kinetics of laccase-catalyzed oxidation of phenols 

      Cusola Aumedes, Oriol; Valls Vidal, Cristina; Vidal Lluciá, Teresa; Roncero Vivero, María Blanca (2018-02-01)
      Article
      Accés obert
      In the present work, the laccase kinetics upon the oxidation process of phenolic compounds was studied using cyclic voltammetry (CV). Several hydroxybenzoic and cinnamic acid compounds were analyzed, and the oxidation ...

    • Using glycosidases to modify TCF bleached specialty sisal fibers
