Phytoremediation, the use of vegetation for the in situ treatment of contaminated soils and sediments, is an emerging technology that promises the effective and inexpensive cleanup of hazardous waste sites. In present study, we used three plant species (Brassica juncea, Sorghum vulgare, and Phaseolus mungo) for the remediation of textile effluent. The B. juncea, S. vulgare and P. mungo demonstrated decolorization of textile effluent up to 79, 57, and 53%, respectively. The shoot length of S. vulgare and shoot and root length of P. mungo was significantly affected because of textile effluent toxicity. However, B. juncea was found to be the most tolerant, effective color removing and heavy metal extracting agent as compared to other tested plant species. The B. juncea was also used to degrade exemplary dye reactive red 2 and the metabolites were identified as napthalenesufamide (m/z 372) and 2-amino-4, 6-dichlorotriazine (m/z 167). The B. juncea grown using textile effluent showed enhanced vegetative growth with respect to the height of the shoot and root up to 129 and 178%, respectively, as compared to control plants, which indicates utilization and degradation of textile dyes into less toxic products. Significant induction of intracellular laccase (266%) was observed in the case of B. juncea, indicating its crucial role for a potential metabolism and further degradation of the textile effluent.
