摘　　要：采用索氏提取法、考马斯亮蓝法、Somogyi法分别对静止培养和通气培养的牟氏角毛藻(Chaetoceros muelleri)内的脂肪、蛋白质、碳水化合物等营养组分的含量进行了测试分析。结果表明:静止培养的牟氏角毛藻营养物质含量高于通气培养的牟氏角毛藻营养物质含量。静止培养条件下牟氏角毛藻中脂肪含量为26.425%,蛋白质含量为0.816%,碳水化合物含量为10.7%;通气培养条件下牟氏角毛藻中脂肪含量为24.396%,蛋白质含量为0.474%,碳水化合物含量为7.840%。Contents of lipids, proteins and carbohydrates in the cells of Chaetoceros muelleri, which cultivated in aerobic and anaerobic photobioreactors, were measured by the Soxhlet extraction method, Bradford method and Somogyi method, respectively. The results showed that the content of nutrimental substances in the cells of anaerobic cultures of C. muelleri is higher than them in the aerobic cultured cells. The content of lipid, protein and carbohydrate were 26.425%, 0.816%, and 10.7%, respectively in anaerobic cultured cells. While in the aerobic cultures they were 24.396%, 0.474%, and 7.84%, respectively.
