Decolourisation of synthetic textile dyes by using Calocybe indica


Bhuvaneswari Manivel, Subashini Rajkumar, Vijayalakshmi Selvakumar, H Dharani

The present study reveals the potentials of macrofungi namely Calocybe indica for decolourization of dye. Azo dyes are released in large quantities into the environment from textile industries. These dyes are recalcitrant to microbial degradation, causing problems in the usual biological treatment of the industrial effluents. Pollution is particularly associated with the reactive azo dyes, because of their strong colour which leads to aesthetic problems and obstructs light penetration and oxygen transfer into water bodies. Biomass production varied with different fungal isolates in the decolurization of dyes. The decolorization of viscose orange-A was found to be 78.54 and 94.72%, with Calocybe indica -1 and Calocybe indica -2 respectively after 15 days of incubation. The decolorization of direct green PLS, was found to be 81.56% and 66.41 with Calocybe indica -1 and Calocybe indica -2 respectively after 15 days of incubation. Among the two fungi, Calocybe indica -1 produced the maximum fungal biomass. Fungal isolates showed a highly correlation between the dry weight of the fungi and colour removal percentage.
