Enzymatic colouration with laccase and peroxidases: Recent progress

Enzymes have received significant attention as alternative catalysts to chemical auxiliaries in textile processing. For example, laccases and peroxidises are promising alternatives for bleaching and denim stone washing processes. Similarly, the ability to oxidise different phenolic substrates and dye precusors resulting in the formation of different coloured polymeric molecules is being exploited for developing green chemistry dyeing processes. The enzymatic process is simpler than conventional coloration processes, giving economic and environmental benefits. In this review, the applications of laccase and peroxidise enzymes in dyeing processes of various textile meterials is discussed. © 2012 Informa UK, Ltd.
