Bioscouring refers to the enzymatic removal of pectins and waxes from the surface of a cotton fiber, which endows it withimproved bleachability and dyeability. This process preserves the fiber?s structure and strength, and avoids the high energy consumption and severe pollution problems that are associated with conventional alkaline treatments. In the present study Pectinase enzyme was extracted from marine Bacillus subtilis isolated from marine sediment sample collected from Chinchani
beach, India and was optimized under different cultural conditions. The partially purified enzyme was used in the scouring of the
cotton fabric. It was observed that water absorbing capacity of the enzymatically scoured fabric was comparable with the alkaline
scoured fabric. In addition when both the enzymatically scoured cotton as well as alkaline scoured cotton was dyed, colour strength values determined were more or less similar indicating efficient removal of pectin from graige cotton.
