Ourococcus multisporus YSW008을 이용한 폐수고도처리 및 바이오에너지 생산 가능성 평가

초록

This study demonstrates the potential of Ourococcus multisporus YSW008 for removal of nitrogen and phosphorus from different types of wastewaters(municipal wastewater - influent, secondary and tertiary effluents, and piggery wastewater effluent) with simultaneous production of algal biofuel feedstock. Municipal wastewater supported a higher growth(0.2 to 0.22 g/L) compared to the piggery wastewater after 10 days of cultivation. Removal efficiency of nitrogen and phosphorus in municipal wastewater was 94 and 95%, respectively. The microalgal carbohydrate and fatty acid contents cultivated in municipal wastewater were 31 and 9% higher compared to the piggery wastewater. The content of oleic acid was 2.5 times higher in the municipal wastewater than in the piggery wastewater. The results showed that O. multisporus has a higher potential of nitrogen and phosphorus removal from municipal wastewater compared to piggery wastewater, with simultaneous production of algal biomass for biofuel feedstock.
