摘要Effect of salinity (15, 25, 35, 45, and 55 parts per thousand) on growth, biochemical composition, and lipid productivity of Nannochloropsis oculata CS 179 was investigated under controlled cultivation in a 19-day study. The results demonstrate that the dry biomass of N. oculata was the highest at a salinity of 25 parts per thousand among the treatments in the first 10-day cultivation (P<0.05). During days 1419 (stage III), the dry biomass productivity was the highest at a salinity of 35 parts per thousand (P<0.05). The algae had the highest chlorophyll a content (26.47 mg g-1) at 25 parts per thousand in stage I, and it decreased continuously at stage III. Protein content (as% of dry biomass) of algae reached the highest value of 42.25 +/- 2.10% at 15 parts per thousand, and the lipid content was the highest of 32.11 +/- 1.30% of dry biomass at 25 parts per thousand. However, the lipid productivity of these algae was the highest at 35 parts per thousand (64.71 mg L-1 d-1; P<0.001). C16 series content was the highest among the total fatty acid methyl esters (FAME), and eicosapentaenoic acid C20:5n-3 (EPA) content was high at the low salinity. Fatty acid profiles of N. oculata varied significantly under different salinities.
