Phytoremediation of phenolic compounds: Recent advances and perspectives (original) (raw)

Abstract

Phenolic compounds present in the drainage from several industries are harmful pollutants and represent a potential danger to human health. Conventional treatments for phenol removal from industrial wastewaters have several limitations so, there is a need to look for alternative and environmental friendly technologies to complement or substitute the conventional ones. In recent years, phytoremediation has been recognized as a cheap and eco-friendly alternative technology which could be used for the remediation of organic contaminants, such as phenolics. Despite most phytoremediation studies were performed with soil-grown or hydroponically grown plants; more recently some results were obtained with the help of in vitro cell and tissue cultures, such as hairy roots. They have been used as tools for screening the potencialities of different plant species to tolerate, accumulate and remove high concentrations of phenols with high efficiency. In addition, using different plant model syst...
