In this work the 'EDTA-enzyme-substrate' interaction was investigated in linen biopreparation. The effect of EDTA on the degradation of non-cellulosic constituents during bioscouring with pectinase enzyme was investigated in detail. Greige linen fabric was treated with pectinase, pectinase supplemented with ethylenediamine-tetra-acetic acid (EDTA), and EDTA pre-treatment followed by pectinase, in a tumble agitated bath. Adding EDTA to the enzyme solution accelerated the degree of hydrolysis and resulted in higher reducing sugar liberation and more efficient calcium ion extraction, indicating a synergistic effect of enzyme and EDTA. However, when EDTA was applied as a pre-treatment, a decrease in the efficiency of the subsequent enzymatic hydrolysis was observed.
