Batch, modified semi-continuous and continuous cultivations of Chlorella vulgaris C9-JN 2010 cells in municipal effluent were performed and analyzed. The experiments were carried out in 7.5-L photo-bioreactors, to which 2% of CO2 was supplied. Biomass and specific growth rate of C. vulgaris were 0.528-0.760gl(-1) and 0.200-0.374d(-1), respectively. Meanwhile, it could efficiently remove ammonia-N, total nitrogen, total phosphorus, CODCr and BOD5 by around 98.0%, 90.9-93.6%, 89.9-91.8%, 60.7-90.0% and 83.4-88.4%, respectively. Algal protein content was 550±30.0mgg(-1) of the harvested biomass of C. vulgaris which was rich in eight kinds of essential amino acids (around 44.5% of the total). The processes of cultivation of C. vulgaris in municipal effluent could be proposed as dual-beneficial approaches, which could produce profitable byproducts and simultaneously reduce the contaminations to environment.
在城市污水中进行了小球藻 C9-JN2010 细胞的批量、改良半连续和连续培养,并进行了分析。实验在 7.5-L 光生物反应器中进行,其中供应了 2%的 CO2。小球藻的生物量和比生长速率分别为 0.528-0.760gl(-1)和 0.200-0.374d(-1)。同时,它可以有效地去除氨氮、总氮、总磷、CODCr 和 BOD5,去除率分别约为 98.0%、90.9-93.6%、89.9-91.8%、60.7-90.0%和 83.4-88.4%。小球藻收获生物量的藻蛋白含量为 550±30.0mgg(-1),其中富含八种必需氨基酸(约占总氨基酸的 44.5%)。在城市污水中培养小球藻的过程可以作为双重有益方法,既能产生有利可图的副产品,又能同时减少对环境的污染。
