In this work, nanofibrillated cellulose (NFC) has been evaluated as a potential reinforcement for cement mortar composites. Two types of vegetable fibres with different composition and properties (cellulose content and microfibrillar angle), sisal, a

Seven natural phenols and two synthetic compounds were evaluated by means of cyclic voltammetry as enhancers for the oxidation of the lignin model compound veratryl alcohol (VAl) and a sulfonated lignin (SL). Their electrochemical behaviors and catal

The oxidation of sisal pulp fibers by the laccase–TEMPO system was investigated and the influence of process variables including the laccase and TEMPO doses, and reaction time, on various properties of the oxidized fibers and of handsheets made fro

Enhancing the effectiveness of a laccase–TEMPO treatment on sisal pulp by increasing pulp consistency was for the first time found to increase the biorefining potential of this enzyme–mediator system. The operating conditions used were those prev

This paper reports a comparative study of the effects induced on sisal pulp fibers by three different laccase-based systems, namely, laccase–sinapyl aldehyde, laccase–ferulic acid, and laccase–TEMPO systems, applied to perform biobleaching, bio

The aim of this study was to investigate the oxidation of sisal pulp fibers by laccase–TEMPO system which had never previously been examined. High cellulose content sisal fibers were treated with laccase from Trametes villosa and a varying amount o

This work was conceived to investigate for the first time the effectiveness of the combined use of xylanase and laccase for the removal of hexenuronic acids (HexA) and lignin from sisal pulp fibres. To this end, xylanase (X) and laccase (L) treatment

The effects of laccase-natural mediator systems (LMS) on sisal pulp and their potential for either biobleaching or functionalizing (via radical-coupling) its fibres were investigated. The enzyme treatment (L stage) was followed by extraction with hyd
