Recycling of industrial and domestic wastewater is a big challenge for a man in todayâ??s world. Unimaginable and rapid industrialization, urbanization and growth in agriculture that have occurred in the past few decays to meet the demands of the growing human population has led to the first degradation of our mother earth. Presently and in future wastewater will remain a huge resource of usable water when appropriate treatment process is adopted. This would make the wastewater meet the drinking water qualities standard. Removal of heavy metals from industrial wastewater is of special concern. Since the presence of heavy metals poses great health hazards to humans and all other life on our planet. Bioremediation that uses microorganisms like algae, bacteria etc is a cost-effective, energy efficient & non-polluting technique. Bioremedial efficacy of Nostoc carneum was assessed experimentally in the laboratory. A pure strain of Nostoc carneum Agardh cultured in BGII medium under continuous white light (2000lux) & at 25±20C temperature was used for removal of chromium in aqueous solution. The results showed the qmax value of Nostoc carneum for chromium adsorption to be 1700μg/g dry weight. The equilibrium of adsorption was attained at 10 hours of inoculation. The paper deals with the adsorptive capability of Nostoc carneum aimed at its use as an agent of heavy metal removal from natural aquatic habitats thus rendering the contaminated wastewater safe for irrigation, aquaculture, and domestic purpose.
