- This study was conducted to investigate the removal rate of nitrogen and phosphorus, and lipid production from a swine wastewater by Botryococcus braunii UTEX 572 in an outdoor photobioreactor. B. braunii successfully predominated in competition with bacteria and other algae, especially Oscillatoria, which were grown spontaneously in a secondary-treated swine wastewater, under the conditions of incubation temperature at 25°C and increased inoculum amount at 287 mg/l. There was a significant relationship between dry weight of B. braunii and absorbance of culture solution at 680 nm (r2= 0.967), suggesting that the latter is as good as the former commonly used for the measurement of algal biomass which is considerably time- consuming. The removal rates of COD, TOC, total nitrogen, and total phosphorus from the swine wastewater by B. braunii were 0.83 mg/l/d, 0.61, 0.69, and 0.16, during an incubation of 18 days. The lipid contents of B. braunii on a dry weight basis in Chu 13 medium and swine wastewater were 33.2±2.6% and 32.8±3.2, respectively, which showing no difference between them. These results suggested that the mass cultivation of B. braunii in an outdoor photobioreactor could be used for the advanced treatment of swine wastewater and lipid production.
