Chloro-Ag is a renewable bioadsorbent that is synthesised for an environmentally friendly bioremediation of wastewater generated from various industry. This biomaterial was synthesised using extremophile photosynthetic microorganisms which is robust and performed maximum remediation under wide range of environmental fluctuation. In addition, not only able to remediate the effluent, this bioabsorbent also accumulate chemical precursor that can be converted into bioenergy.
