Biopreparation may be a valuable and environmentally friendly alternative to harsh alkaline chemicals for preparing of cotton. In bioscouring the removal of the noncellulosic substances can be achieved mainly by hydrolytic enzymes, such as pectinase, amylase, xylanases and cellulases. The bioprocess has several advantages over conventional chemical scoring. Enzymes operate under mild conditions (pH, temperature) with low water consumption and act only on specific substrates.

Modem society expects biotechnology to be the answer for many worldwide problems like depletion of energy sources, incurable illnesses and pollution, among other problems. Textile processing is a growing industry that traditionally has used a lot of water, energy and harsh chemicals starting from pesticides for cotton-growing to high amounts of wash waters that result in waste streams causing high environmental burdens. As textile fibers are polymers, the majority being of natural origin, it is reasonable to expect there would be a lot of opport1Jnities for the application of white biotechnology to textile processing. Enzymes nature's catalysts are the logical tools for development of new biotechnology based solutions for textile wet processing. The enzymes are selected based on their pH and temperature compatibility. The most effective conditions for this process are established in regard to the properties of the scoured goods.
