Commercial production of renewable energy feedstocks from microalgae will require reliable and scalable growth systems. Two and one half years of biomass and lipid productivity data were obtained with an industrial-scale outdoor photobioreactor operated in Fort Collins, Colorado (USA). The annualized volumetric growth rates for Nannochloropsis oculata (CCMP 525) and Nannochloropsis salina (CCMP 1776) were 0.16 g L(-1) d(-1) (peak=0.37 g L(-1) d(-1)) and 0.15 g L(-1) d(-1) (peak=0.37 g L(-1) d(-1)) respectively. The collective average lipid production was 10.7 m3 ha(-1) yr(-1) with a peak value of 36.3 m3 ha(-1) yr(-1). Results from this study are unique based on publication of biomass and corresponding lipid content combined with demonstration of energy savings realized through analysis of gas delivery requirements, water recycling from successive harvests with no effect on productivity, and culture stability through serial batch lineage data and chemotaxonomic analysis of fatty acid contents.
从微藻中商业生产可再生能源原料需要可靠和可扩展的生长系统。在美国科罗拉多州柯林斯堡的一个工业规模的户外光生物反应器中进行了两年半的生物质和脂质生产力数据的获取。Nannochloropsis oculata（CCMP 525）和Nannochloropsis salina（CCMP 1776）的年容积增长率分别为 0.16 g L(-1) d(-1)（峰值=0.37 g L(-1) d(-1)）和 0.15 g L(-1) d(-1)（峰值=0.37 g L(-1) d(-1)）。集体平均脂质产量为 10.7 m3 ha(-1) yr(-1)，峰值为 36.3 m3 ha(-1) yr(-1)。基于出版物中生物质和相应脂质含量的结合，以及通过分析气体输送要求、连续收获的水再循环对生产力没有影响、通过连续批次谱系数据和脂肪酸含量的化学分类分析实现的文化稳定性，本研究的结果是独一无二的。
