Endophytic colonies and plant associations are benefcial in many ways such as supplying biologically fxed nitrogen, regulation of phytohormone production thus enhancing the plant growth, resistance to environmental stress etc. these associations are also important for the agriculture and in- dustries because they produce important medicinal, agriculture and industrial compounds as endophytic metabolites. When we concern about the waste management, degradation and biotransformation of several toxins, the phytoremediation by using endophytes has been developed as important tool. Current chapter reviles, study and collect most of important knowledge, recent ongoing research, technologies, roles and advancements in biodegradation and biotransformation of diferent types of toxic wastes and their efects on environment with phytoremediation by endophytes. INTRODUCTION Bioremediation is a method of removal of pollutants and wastes from the environment by the use of micro-organisms. According to Ministry of environment and forest, Govt. of India, Bioremediation is the use of biological interventions of biodiversity for mitigation (and wherever possible, complete elimination) of the noxious effects caused by environmental pollutants in a given site. Bioremediation is generally considered to include natural attenuation (little or no human action), bio-stimulation or bio- augmentation, the deliberate addition of natural or engineered micro-organisms to accelerate the desired A Prospective Study on Emerging Role of Phytoremediation by Endophytic Microorganisms Amita Verma Sam Higginbottom Institute of Agriculture, Technology and Sciences (Deemed University), India Parjanya Kumar Shukla Sam Higginbottom Institute of Agriculture, Technology and Sciences (Deemed University), India
