Development of an effective acidogenically digested swine manure-based algal system for improved wastewater treatment and biofuel and feed production

► Coupling low cost and eco-friendly algae-based biofuel with animal feed production. ► Developing an effective algal system on acidogenically digested manure by a 22 CCD way. ► High algal growth rate and nutrient removal rates are obtained from the algal system. ► Having high algal lipid productivity (3.63 g m2 d−1) for low-cost biofuel production.
