The Phyllo sphere represents the habitat provided by the above ground parts of the plants and on a global scale supports a large and complex microbial community. These microbes are the rich source of xylanases which represent one of the largest group of industrial enzymes that have wider applications in food, feed, fuel, textile, paper and pulp industries. In the present study also the phyllospheric microorganism-Aspergillus niger is used for the production of crude xylanase. These xylanases are then subjected for the bio softening and bio bleaching of plant fibre procured from Cleome viscosa. The enzyme treated fibres enhanced with more brightness, greater whiteness index with reduced yellow index, greater tensile strength. The SEM analysis revealed that the enzyme treated fibres showed more bore cracks, peelings, swelling, and external fibrillation on its surface which enhances the surface topology of the fibre. Thus the microrgamisms are ecofriendly and a best alternative for the harmful chemicals used in Industries.
