SCREENING OF FUNGI FOR THE DEGRADATION OF TEXTILE DYES FROM INDUSTRIAL EFFLUENTS
Journal Title: Journal of Biological and Scientific Opinion - Year 2013, Vol 1, Issue 4
Abstract
The objective of the study was to investigate the potential dye degrading fungal species from textile mill effluents in a cost effective and eco friendly manner. Decolorizing isolates of Zygomycotina, Deuteromycotina and Ascomycetes were isolated from dye industry effluents. Decolorization assay was carried out on both solid and liquid assay medium along with laccase activity. Among all the fungi, Aspergillus was a dominant species recorded among the effluents. All the fungal isolates were tested for decolorizing activity against methylene blue, crystal violet, sudan black, malachite green and methyl red. On solid and liquid medium, Aspergillus terreus, A. niger, and Fusarium moniliforme were found to decolorize maximum number of dyes and registered maximum percentage of color reduction. Laccase assay was done using Lignin modifying enzyme basal medium with Hydroxybenzotriazole, and among the isolates, F. moniliforme and A. terreus were found to produce the laccase enzyme. Among the 13 species of fungal isolates, the maximum degradation activity was shown by A. terreus (86.33 %), followed by A. niger (84.20) and F. moniliforme (80.00 %) seems to be potential candidates to degrade commonly used dyes. So these strains can be used for treating the dye containing effluents as well as in bio remediating degraded aquatic and land polluted by these effluents. So, commercial development and application of this fungus for textile wastewater treatment will be an advantage to dye removal process.
