The effects of nutritional requirement for growth and decolorization of textile dye by indigenous fungal
isolates have been studied using .Duncan multiple range test and analysis of variance. Maximum decolorization was
observed at 0.5-1 M nitrogen concentration by the selected strains, where higher concentration had a negative effect.
Growth also showed their maximal (0.35 gm 100 mL-1 by SA 1, 0.27 gm 100 mL-1 by SA 2 and 0.31 gm 100 mL-1
by SA 3) in this range with all tested strains. All the fungal strains showed significant correlation with nitrogen
concentration (R2 0.82, 0.77 and 0.88 of Aspergillus Niger SA 1, Aspergillus flavus SA 2 and Aspergillus terreus
SA 3 respectively. Similar results observed for increased in concentration of carbon source as there was increasing
trend of decolorization efficiencies of all the selected fungal strains (R2 0.85, 0.76 and 0.97 of SA1, SA2 and SA3,
respectively). The comparison of the fungal response obtained, suggests that Aspergillus flavus SA2 yielded the best
result of 80.72% which was followed by Aspergillus Niger SA1 behaving 78.29% decolorization Aspergillus terreus
SA3 rated third within selected strains by rendering a percentage of 78.29.
