ABSTRACT
Phytotechnologies are comprehended as the result of interdisciplinary studies, involving knowledge of biology and plant biochemistry, soil chemistry and microbiology, ecology, environmental engineering, among other disciplines. phytostabilization is based on the conversion of pollutants to less bioavailable forms by sorption onto roots, precipitation, complexation or metal reduction in the rhizosphere, such as the case of Cr(VI) to Cr(III) reduction which is a more mobile and less toxic species. Increasing the efficiency of phytoremediation processes is one of the challenges to solve. Phytoremediation sustainability is still questioned by scientific and nonscientific stakeholders. Since the beginning, safe disposal of contaminant enriched biomass has been the main concern of phytotechnologies, thus different strategies have been explored to achieve this goal. Thereby, deriving valuable phyto-products from the biomass generated after the clean-up process is a global technological challenge to bring these phytotechnologies into the gear of a bio-based economy and references therein.
