ABSTRACT
Wastewater treatment using microalgae is an environmental friendly practice, involving various interactions among
the micro and macro fauna and flora of treatment plant. The use of algal-bacterial consortia for wastewater
treatments has proved more effective in biomass production, nutrient cycling and bioremediation of organic
pollutants, heavy metals and many other contaminants. The biodegradation approach of involving consortium might
attain self-sustaining level and may prove technically cheaper and advance technology. It will finally help in dealing
the dual mission of producing valuable metabolites and pollutants/nutrients removal from wastes/wastewaters.
Agricultural wastes/residues generated abundantly in energy deficient countries like Pakistan, having enormous
energy potential, are not utilized efficiently and considered as wastes only. The present review focuses on the current
research on algal-bacterial consortia and the construction of consortia by keeping in view the environmental
conditions of country, suitable for microalgal growth to deal with pollution control and production of animal/fish feed
and other valuable metabolites.
