Abstract
Phytoremediation is a new emerging tool for reducing the concentrations
and toxic effects of contaminants in the environment with the help of plants
and associated soil microbes. Phytoremediation is acknowledged as an efficient
and affordable method for restoring the environment. Aquatic contamination
is increasing day by day due to different natural and anthropogenic activities
leading to soil, water and food chain contamination. These activities are
hazardous to the climate. Various types of potential approaches are beneficial
for removing toxicants from aquatic ecosystems among them phycoremediation is a
low-risk and environmentally friendly clean-up method where algae are used to
decontaminate the environment. Cyanobacteria (blue-green algae) are more
effective, affordable and eco-friendly alternative to conventional
physico-chemical remediation methods. Due to their tremendous adaptability and
effective protective mechanisms against various abiotic stresses, cyanobacteria
occur in diverse habitats, such as terrestrial and aquatic, even at extreme
climatic conditions and polluted waters. Many cyanobacterial species are effective
in removing heavy metals from aquatic ecosystems. This review highlights the
role of cyanobacteria in eco-friendly detoxification and the effective
degradation of various types of toxicants present in different water bodies.
