Dhakshnamoorthy Manikandan, Francis Gricilda Shoba

Abstract :

<p>&nbsp;Many natural dyes have been known for a long time. They were obtained from animal and vegetable sources. Organic compounds have an ability to impart their color to the material to be dyed, in an aqueous medium. Dyes can be classified according to their chemical constitution or on the basis of application to fibers. Fungi from the Basidiomycetes group are known as white rot fungi are heterogenous group of microorganisms but have in common the capacity to degrade lignin as well as other wood components. The white rot fungi are by far the most efficient liginiolytic microorganisms. They are able to degrade a wide variety of recalcitrant pollutants including various types of dyes. In this study white rot fungi from various geographical regions were collected and screened for laccase production. Potential strains were selected and classical mutation study was carried out and finally dye decolorization was compared between wild and mutant.</p>
