Abstract

There is a growing demand to substitute most traditional chemical processes with biotechnological processes involving microorganisms and enzymes such as pectinases, xylanases, cellulases laccases and ligninases for industrial applications, which not only provide an economically feasible alternative to the industries but are also more environment friendly. Recently, there have been several reports on the application of alkaline pectinases. In the textile industry it is used for the retting and degumming of fibre crops. It is also used for the production of good quality paper. Alkaline pectinases are being used for the pretreatment of wastewater from vegetable food processing industries containing pectinacious material, for the processing and degumming of plant fibres such as ramie (Boehmeria nivea), sun hemp (Crotalaria juncea), buel (Grewia optiva), flax (Lisum usitatissimum), and jute (Chorchorus capsularis), as well as for debarking and depolymerizing.
