Axonopus, a potential plant for phytoremediation: A review
Sandeepa Agarwalla, Dipika Rajput
Phytoremediation is a new and promising approach that helps in restoring and reclaiming soils that are contaminated with noxious metals, with the help of plants and associated microflora. It is quite an innovative way to restore environment. Choice of the mechanism of phytoremediation and choice of plants depends on the tolerance capacity of the plant species. Different plant species have different tolerance capacity to accumulate heavy metals after which they detoxify them. Some plants are better accumulators of lead while others may be of zinc and still there may be some plants that can produce certain enzymes for detoxification. It can help to improve the overall ecological health of a particular affected site with minimization of negative impacts with thorough investigation and observation. Axonopuscompressus belonging to the Poaceae family is one of the potent plants that can play an important role in the protection of the ecosystem due to its better adaptability and tolerance towards some of the heavy metals and crude oil. It cost-effectively helps in decontamination. They are biologically safe and provide aesthetic beauty.
