【摘要】The nutrition values of microalgae, Naanochloropsis oculata, in different growth phases were analyzed. The results indicated growth phase had effects on the main nutrition values of N. oculata. The algae in exponential phase have the highest crude protein content (33.99%) and the lowest (28.33 % ) in stationary phase. But the algae in stationary phase and phase of declining relative growth had higher amino acid content, 225.02mg. g-1 and 214.82 mg·g-1 respectively. The algae in exponential phase had the lowest amino acid content (98.87 mg·g-1 ). The total lipid content of algae in phase of declining relative growth was significantly higher than those in exponential phase and stationary phase. As the alga grew, the composition of fatty acid was changing and the compositions of EPA and PUFA declining. From the viewpoint of nutritional value and growth characteristics of microalgae, the phase of declining relative growth is the best harvest time of N. oculata under the batch culture model.
