摘    要:
测定7种小球藻(普通小球藻(C.vul)、自养小球藻(C.aut)、海水小球藻(C.spp.)、微小小球藻(C.min)、蛋白核小球藻(C.pyr)、原始小球藻(C.pro)、椭圆核小球藻(C.ell))氨基酸的组成,对其营养进行评价,并利用多元分析法对7种小球藻的氨基酸含量差异进行比较分析。结果显示:7种小球藻氨基酸种类齐全,必需氨基酸占氨基酸总量的比例分别达到35.86%、39.75%、37.58%、36.35%、38.05%、37.98%、40.28%。必需氨基酸指数分别为66.63、79.41、67.96、71.17、57.69、70.02、65.39。聚类分析与主成分分析表明4种海水藻氨基酸含量可以聚为一类,3种淡水藻氨基酸含量可以聚为一类,主成分分析构建了3个主成分,其贡献率:主成分1为73.727%,主成分2为10.021%,主成分3为7.052%,累积贡献率为90.80%。

关 键 词:小球藻  氨基酸  多元分析

Abstract:
Multivariate analysis was conducted to evaluate the amino acid composition and nutritional values of 7 types of Chlorella including Chlorella vulgaris,Chlorella autotrophica,Chlorella minutissim,Chlorella spp.,Chlorella pyrenoidosa,Chlorella protothecoides and Chlorella ellipsoidea.The results showed all kinds of amino acids were detected in the 7 types of Chlorella.The ratios between essential amino acids and total amino acids were 35.86%,39.75%,37.58%,36.35%,38.05%,37.98% and 40.28%,and the essential amin...
Keywords:Chlorella  amino acid  multivariate analysis
