Degradation of textile dyes by Aspergillus fumigatus strain and their culture optimization

Synthetic dyes used in textile industries, if not treated prior to its disposal, can enter our water systems and cause pollution. The present investigation focused on the decolorization of the textile dyes like Congo red, Malchite green. The present Aspergillus fumigatus were isolated from marine soil samples collected from Bay of Bengal, Kakinada, East goghavari district, Andhrapradesh, India. Different parameters such as various carbon source, nitrogen source, temperature, pH and salinity concentrations were optimized for decolorization of textile dyes Congo red Malchite green by Aspergillus fumigatus showed maximum dye decolorization of 90% at the end of 5th day under optimum condition and found to be more efficient in dye decolorization. All parameters studied in this paper were found to be effective for all isolates. The results reported here warrant further investigation to establish the usefulness of these isolates for bioremediation and biodegradation application such as waste water treatment.
