Application of enzymes for textile fibres processing

Abstract

This review highlights the use of enzymes in the textile industry, covering both current commercial processes and research in this field. Amylases have been used for desizing since the middle of the last century. Enzymes used in detergent formulations have also been successfully used over the past 40 years. The application of cellulases for denim finishing and laccases for decolourization of textile effluents and textile bleaching are the most recent commercial advances. New developments rely on the modification of natural and synthetic fibres. Advances in enzymology, molecular biology and screening techniques provide possibilities for the development of new enzyme-based processes for a more environmentally friendly approach in the textile industry.

Stimulation of laccases from Trametes pubescens: Use in dye decolorization and cotton bleaching

“…The basic pH can damage the fibers and high water volumes are consumed during several washing steps (37). Thus, traditional treatments alone need large amounts of chemicals, energy and water, increasing, of course, the final process costs.…”

“…Thus, traditional treatments alone need large amounts of chemicals, energy and water, increasing, of course, the final process costs. However, coupling chemical and enzymatic treatments, the actual consumption of H 2 O 2 and water is reduced, increasing the environmental sustainability of the process (37).…”

Chromatography as the Major Tool in the Identification and the Structure-Function Relationship Study of Amylolytic Enzymes from Saccharomycopsis Fibuligera R64

“…This situation strengthens the position of S. fibuligera for bioethanol production, being a raw starch degrading enzyme producer. α-Amylase is commonly used in food, beverage, paper industries (8), in textile industry and as additive in detergents (9,10), for renewable energy (11,12) and medical purpose (13). Glucoamylase has been the most important enzyme in food industry, mainly in the production of sugar or ethanol (14).…”

Bioremediation Potential of Mixed White Rot Culture of Pleurotus Ostreatus IBL-02 and Coriolus Versicolor IBL-04 for Textile Industry Wastewater

“…The use of biotechnology in the processing of fibers and textiles is rapidly gaining wider recognition because of its non-toxic and ecofriendly characteristics [6]. Among the low-cost and viable alternatives available for effluent treatment, biological processes are recognized by their capacity to reduce biochemical oxygen demand (BOD) and chemical oxygen demand (COD) [9].…”

“…Conventional methods for dealing with textile wastewater consist of various combinations of biological, pHysical and chemical methods [5][6][7]. Unfortunately, although the conventional chemical and pHysical methods are versatile and useful, but only transfer the pollutant from one form to another [8], and end up in producing secondary waste products.…”
