摘要
以平方欧氏距离为相似性测度,类间距用离差平方和法,对11属30株海洋绿藻所含脂肪酸进行聚类分析,结果分为5类。类Ⅰ含EPA和DHA最高;类Ⅳ含总(n-3)PUFAs最高。混合培养小球藻C95,C97与杜氏藻C33,C42,可能得到EPA,DHA和其它(n-3)PUFAs含量最丰的绿藻种群。系统聚类分析为海洋绿藻分类与量化评价提供了一种好方法。
30 strains of 11 genera of marine green algae were classified into 5 groups by carrying out a cluster analysis of fatty acids, while squared Eucliden distance was used as similarity measure and ward method as clustering algrithm. Group I had the highest content of EPA and DHA; Group IV had the highest content of total (n-3) PUFAs. A new community of green algae could be cultured to product high levels of EPA, DHA and other(n-3)PUFAs by mixing up two Cohlorella C95,C97 and two Dunaliella C33, C42. So hierarchical cluster analysis was suggested be a good method of classification and quan-titive evaluation on marine green algae.
