测定了海水养殖中常用的六种微藻中核黄素（一种海水养殖动物必需的维生素）的浓度。这是两种硅藻（毛囊毛藻，假海藻）；两个原体植物（Isochrysis sp.（克隆t.o iso）， Pavlova lutheri）；一个绿藻（Nannochloris atomus）和一个真真菌（Nannochloropsis oculata）。在对数和平稳生长阶段对培养物进行了分析。对数生长期核黄素（g-1干重）的比例为20 (T. pseudonana) ~ 40 （Isochrysis sp. T. iso）。随着固定期的开始，核黄素在各种属中所占比例均有所增加；在薄叶蓟马、伪蓟马和原子蓟马的培养中增幅最大（2- 3倍）。毛羽毛羽的核黄素含量（106马克g-1）高于其他所有物种（48 ~ 61马克g-1）。尽管不同微藻的组成不同，在对数生长和平稳生长阶段，所有物种都应该为海水养殖动物提供丰富的核黄素来源。
Concentrations of riboflavin -a vitamin essential for maricultured animals-were measured in six species of microalgae commonly used in mariculture. These were two diatoms (Chaetoceros gracilis, Thalassiosira pseudonana); two prymnesiophytes (Isochrysis sp. (clone T.ISO), Pavlova lutheri); one chlorophyte (Nannochloris atomus) and one eustigmatophyte (Nannochloropsis oculata). Cultures were analysed during both logarithmic and stationary growth phase.The proportions of riboflavin (mug g-1 dry weight) during logarithmic growth-phase ranged from 20 (T. pseudonana) to 40 mug g-1 (Isochrysis sp. T.ISO). With the onset of stationary phase, the proportion of riboflavin increased in all species; the increase was most dramatic in cultures of C gracilis, T pseudonana and N. atomus (2- to 3-fold). Chaetoceros gracilis contained more riboflavin (106 mug g-1) than all other species (48 to 61 mug g-1).Despite the differences in the composition of the different microalgae, across both logarithmic and stationary growth-phases, all species should provide a rich source of riboflavin for maricultured animals.
