Microalgae Biomass Production in High Nutrient Wastewater: A Review

Abstract

The ability of microalgae in phycoremediation of wastewater and biomass production for animal food, fertilizer, and source of renewable energy has sparked the interest to investigate the microalgae nitrate assimilation and biomass production in high nutrient wastewater, especially in nitrified landfill leachate (NLL). This paper reviews the dual role of autotrophic microalgae in phycoremediation of high nutrient wastewater and as a source of feedstock for energy generation. The use of microalgae for nutrient removal, factors affecting the growth and analysis of the biomass for potential bioenergy substrate are discussed.
