Enzymatic delignification with laccase from Trametes villosa used in combination with chemical mediators (acetosyringone, acetovanillone and 1-hydroxybenzotriazole) to improve the totally chlorine-free (TCF) bleaching of kenaf pulp was studied. The b

Nine phenol derivatives, p-coumaric acid (PC), vanillin (V), acetovanillone (AV), acetosyringone (AS), syringaldehyde (SA), coniferaldehyde (CLD), ferulic acid (FRC), sinapic acid (SNC), and sinapyl aldehyde (SLD) were assayed as laccase redox mediat

Effects of laccase-natural mediator systems on kenaf pulp

Autor: Glòria Andreu, Teresa Vidal

Publikováno v: Bioresource Technology. 102:5932-5937

This paper reports the first application of laccase-mediator systems (LMS) to kenaf pulp. Five natural phenolic compounds (acetosyringone, syringaldehyde, p-coumaric acid, vanillin and acetovanillone) were used as mediators in combination with laccas

A new biobleaching sequence for kenaf pulp: influence of the chemical nature of the mediator and thermogravimetric analysis of the pulp

Autor: Glòria Andreu, Teresa Vidal, Agustín García Barneto

Publikováno v: Bioresource technology. 130

This paper evaluates five phenolic compounds as mediators for kenaf pulp biobleaching by laccase. The results have been compared with the treatment using a non-phenolic mediator, 1-hydroxybenzotriole and laccase alone. The influence of the nature of

In this work, kenaf pulp was delignified by using laccase in combination with various redox mediators and the efficiency of the different laccase–mediator systems assessed in terms of the changes in pulp properties after bleaching. The oxidative ab
