Final Report - ENZUP (Enzymatic Up-grading of Wool Fibres)

Project ID: 32877
Funded under: FP6-SME

Abstract

Felting shrinkage, which is a typical property of wool due to the configuration of the scales of the wool fibre, is a serious problem, especially during washing. Enzymatic treatment represents a very interesting alternative to chlorination. Proteolytic enzymes are known to penetrate and degrade the internal wool structure during processing, causing fibre damage.

The ENZUP project targeted this problem. The proteases were genetic engineered and modified to have large molecular sizes which limited the enzyme penetration into the fibres. The results stated here in their final report are of great importance where, for the first time, the microbial production of a chimeric high molecular weight protease for wool surface hydrolysis was reported. Their final report lists the accomplishments, the patents created as a result and a list of published results.
