| 摘 要： | 实验对海洋红酵母(沼泽生红冬孢酵母)的基础营养成分、脂肪酸和氨基酸进行了研究和分析。结果发现,沼泽生红冬孢酵母的粗蛋白含量为42.01%,粗脂肪为3.09%,总糖为29.5%,粗灰分为8.59%,水分为5.28%。必需氨基酸含量丰富和组成合理,脂肪酸的主要组分为C18:1、C17:1、C16:0和C18:2,表明该菌株具有用作水产饵料生物的营养价值。但该酵母菌缺少水产动物生长所必需的多不饱和脂肪酸EPA和DHA,用作水产动物单细胞蛋白,尤其是作为幼体饵料使用时,需要添加富含多不饱和脂肪酸的藻类作为补充。

| Abstract: | The contents of general nutrients,amino acids and fatty acids compositions of the marine red yeast,R.paludigenum,were analyzed.The contents of crude protein,crude lipid,total sugar,ash and moisture were 42.01%,3.09%,29.5%,8.59% and 5.28%,respectively.Essential amino acids were rich and the composition were reasonable,and the dominant fatty acid of R.paludigenum was C18:1,C17:1,C16:0 and C18:2.The results showed that the strain had an acceptable nutritional value as feed organism for aquaculture animals.Howe... |
