The use of enzymes in textile industry is one of the most rapidly growing fields. It is an example of white/industrial biotechnology which allows the development of environmentally friendly technologies in fibre processing and strategies to improve the final product quality. Cellulases are the most successful enzymes used in textile wet processing, especially finishing of cellulose-based textiles. Traditional stonewashing of jeans involves amylase-mediated removal of starch coating (desizing) and treatment (abrasion) of jeans with pumice stone. In addition, cellulases have been successfully used for the biostoning of jeans and biopolishing of cotton and other cellulosic fabrics. The advantages in the replacement of pumice stones by a cellulose-based treatment include less damage of fibers, increased productivity of the machines, and less work-intensive and environment benign. The consumption of energy and rawmaterials, as well as increased awareness of environmental concerns related to the use and disposal of chemicals into landfills, water or release into the air during chemical processing of textiles are the principal reasons for the application of enzymes in finishing of textile materials. Therefore this project will be focused on investigation oft he Influence of the bioavailability of metal ions in biomass on lignocellulolytic enzymes for implementation in textile processing.
