Phytoremediation: Potential flora for synthetic dyestuff metabolism

Dumping of dye-laden effluents into different environmental compartments adversely affects equilibrium and integrity of ecological systems. being genotoxic,mutagenic and carcinogenic these dyes are quite damaging to health of biota (either aquatic or terrestrial). many of these dyes are resistant to degradation and remediation under natural conditions and through conventional treatment methods. this situation has necessitated the development of effective and efficient wastewater treatment strategies without further stressing the environment and endangering other life forms. to date many biological systems including microorganisms and plants have been assessed for metabolism of dyestuffs. phytoremediation catalyzed by natural solar driven pumps (green plants) and their associated metabolic processes has emerged as a comparatively new approach and has proven to be one of the most effective environmental friendly strategies for removal,detoxification and decolorization of dyes. hence,this review quotes the literature of applied aspects of various plant species and their inherent metabolic as well as extractive potentials which enable them to effectively deal with various coloring agents. © 2015 the authors.
