The eicosapentaenoic acid rich marine eustigmatophyte Nannochloropsis oceanica was grown in wastewaters sampled from four different industries (i.e. pesticides industry, pharmaceutical industry, activated sludge treatment plant of municipality sewage and petroleum (oil) industry). Under the wastewater based growth conditions used in this study, the biomass productivity ranged from 21.78±0.87 to 27.78±0.22mgL(-1)d(-1) in relation to freeze dried biomass, while the lipid productivity varied between 5.59±0.02 and 6.81±0.04mgL(-1)d(-1). Although comparatively higher biomass, lipid and EPA productivity was observed in Conway medium, the %EPA content was similarly observed in pesticides industry and municipal effluents. The results highlight the possibility of selectively using wastewater as a growth medium, demonstrating the elevated eicosapentaenoic acid content and biodiesel properties, that complies with the European standards for biodiesel.
富含二十碳五烯酸的海洋等鞭金藻（Nannochloropsis oceanica）在取自四个不同工业（农药工业、制药工业、城市污水活性污泥处理厂和石油（油）工业）的废水中生长。在本研究中使用的基于废水的生长条件下，相对于冻干生物量，生物量生产力范围为 21.78±0.87 至 27.78±0.22mgL(-1)d(-1)，而脂质生产力在 5.59±0.02 和 6.81±0.04mgL(-1)d(-1)之间变化。尽管在康威培养基中观察到了相对较高的生物量、脂质和 EPA 生产力，但在农药工业和城市废水中同样观察到了类似的%EPA 含量。研究结果突出了选择性使用废水作为生长培养基的可能性，证明了二十碳五烯酸含量和生物柴油特性的提高，符合欧洲生物柴油标准。
