Microalgae have the ability to grow rapidly, synthesize and accumulate large amounts (approximately 20-50% of dry weight) of lipids. A successful and economically viable algae based oil industry depends on the selection of appropriate algal strains. In this study ten species of microalgae were prospected to determine their suitability for oil production: Chaetoceros gracilis, Chaetoceros mulleri, Chlorella vulgaris, Dunaliella sp., Isochrysis sp., Nannochloropsis oculata, Tetraselmis sp., Tetraselmis chui, Tetraselmis tetrathele and Thalassiosira weissflogii. The study was carried out in 3 L glass flasks subjected to constant aeration and controlled artificial illumination and temperature at two different salinities. After harvesting, the extraction of oil was carried out using the Bligh and Dyer method assisted by ultrasound. Results showed that C. gracilis presented the highest oil content and that C. vulgaris presented the highest oil production.
微藻具有快速生长、合成和积累大量（约 20-50%干重）脂质的能力。成功且经济可行的藻类油产业取决于对合适藻种的选择。在这项研究中，我们考察了十种微藻，以确定它们是否适合用于产油：脆杆藻、米勒氏角毛藻、普通小球藻、杜氏盐藻、盐藻、眼点拟微绿球藻、三角褐指藻、钝顶节旋藻、四尾栅藻和威氏海链藻。该研究在 3 L 玻璃烧瓶中进行，在两种不同盐度下进行持续通气和人工控制光照和温度。收获后，使用 Bligh 和 Dyer 法并辅助超声进行油提取。结果表明，脆杆藻的含油率最高，普通小球藻的产油量最高。
