Abstract 

This study was conducted to investigate the production of lipid, and removal of nitrogen and phosphorus from swine wastewater by Botryococcus braunii UTEX 572 in a tubular bioreactor. The rate of dry cell weight increase of B. braunii was highest at 20.1 mg/l/d in a modified Chu 13 medium at 25°C. Under the above conditions, the rate of lipid content increase was also highest at 6.1 mg/l/d. The lipid content of B. braunii on a dry weight basis ranged from 30.5 to 34.1% with an average value of 32.3%. When B. braunii was cultured in a secondary-treated swine wastewater diluted to 50% with tap water, the rate of dry cell weight increase was 18.6 mg/l/d and the rate of lipid content increase was 6.0 mg/l/d. The lipid content ranged from 30.3 to 34.2%. No significant difference was observed between lipid content and growth conditions. The removal rates of nitrogen and phosphorus in swine wastewater were 43.9% and 41.7%, respectively, after 14 days of incubation.
