Enzymatic grafting of natural phenols to flax fibres: Development of antimicrobial properties

► The laccase-phenol treatment could result in the grafting of these phenols onto the fibres. ► These enzyme treatments may permit to give novel or improve properties to flax fibres. ► Bioactive papers have been created: treated papers present high antimicrobial activity. ► The antimicrobial agents grafted are immobilized in the flax fibres.
