Co-cultivation of microalgae and bacteria for optimal bioenergy feedstock production in wastewater by using response surface methodology.

ABSTRACT: This work uses response surface methodology (RSM) to study the co-cultivation of symbiotic indigenous wastewater microalgae and bacteria under different conditions (inoculum ratio of bacteria to microalgae, CO₂, light intensity, and harvest time) for optimal bioenergy feedstock production. The findings of this study demonstrate that the symbiotic microalgae-bacteria culture not only increases total microalgal biomass and lipid productivity, but also enlarges microalgal cell size and stimulates lipid accumulation. Meanwhile, inoculum ratio of bacteria to microalgae, light intensity, CO_2, and harvest time significantly affect biomass and lipid productivity. CO₂ concentration and harvest time have significant interactive effect on lipid productivity. The respo
