| 摘 要： | 对筒柱藻(Cylindrotheca fusiformis)的主要营养成分进行了分析,其中筒柱藻中含有的粗蛋白、粗灰分、粗脂肪和粗纤维含量分别占干重的31.96％、15.10％、12.25％和0.85％.结果表明:所测定的18种氨基酸总量为26.60 g/100g干品,占粗蛋白的83.23％;必需氨基酸(EAA)占粗蛋白的30.79％;呈味氨基酸占粗蛋白的42.12％.筒柱藻还含有多种高不饱和脂肪酸,尤其是EPA,其含量为19.43mg/g干品,达到总脂肪酸含量的15.85％.因此底栖硅藻筒柱藻是一种优良的水产动物苗种饵料.

| Abstract: | In this study,the main nutritional components,the compositions of amino acids and fatty acids were analyzed in Cylindrotheca fusiformis under Fed-Batch-Continuous culture.The results showed that C.fusiformis contains 31.96% crude protein,15.10% ash,12.25% fat and 0.85% fiber,respectively.The content of 18 kinds of amino acids was 26.60 g/100g of dry weight(83.23% of crude protein).Essential amino acids(EAA) and flavor amino acids reached 30.79% and 42.12%,respectively.In addition,C.fusiformis contains a variety of highly unsatured fatty acids,especially EPA.EPA was 19.43 mg/g dry weight(15.85% of total fatty acids). |
