Fungal decolourization study of chemically synthesised malachite green and brilliant green textile dyes
Author(s): Raj Kumar Pandey and Lakshmi Tewari
Abstract: Chemical synthetic dyes are now widely used in many industries such as leather, paper printing, textiles, wool, cosmetics, and food. The major problems associated with the use of dye are that they are resistant to degradation, difficult to remove waste water, non eco-friendly and causing health hazards due to their carcinogenic nature. The use of extracellular enzyme systems from wood rotting fungi are now growing very fast as green technology to biologically remediate such aromatic coloured compounds. In view of above, present study was undertaken for decolorization malachite green and brilliant green using wood rot fungal cultures. Out of various fungal isolates eight fungal isolates and one standard culture of potent Lignolytic fungus Phnerochaete chrysosporium were used for dye decolorization study, both qualitatively and quantitatively. The cultures varied in their dye decolorizing potential, showing 47.31-97.36% and 14.18-93.63% decolorization of malachite green and brilliant green respectively in 24 d. Phase contrast microscopy clearly revealed the asorption of the dyes by fungal cultures (mycelia/spores) in the photomicrographs. Among various cultures tested, the isolate AFP5 showing maximum dye decolorizing/ bioabsorbing ability was found as the most potential isolate.
