Fundamental studies on algal biofilms grown for biological wastewater treatment and as a feedstock for biofuels production were carried out to determine: nutrient uptake capacity, biofilm growth rates, photosynthetic activity, lipid accumulation from nitrogen stress and bicarbonate addition, and algae-bacteria interactions. The algal biofilms were cultured on rotating algal biofilm reactors (RABRs) under varying conditions of light, nutrients, and species composition at bench and pilot scale.
