水栉霉脂肪酸和氨基酸成分分析

Analysis on Fatty Acid and Amino Acid Ingredients in Leptomitus agardh

[目的]为了进一步探讨水栉霉(Leptomitus agardh)的营养价值,对其脂肪酸和氨基酸成分进行了分析。[方法]利用气相色谱-质谱分析仪和氨基酸自动分析仪进行分析。[结果]水栉霉主要脂肪酸成分分别是十六烷酸、十八碳二烯酸、油酸、十八烯酸,其相对质量分数分别为17.238%、12.427%、20.666%、24.121%,其中不饱和脂肪酸相对质量分数为67.981%;含有17种氨基酸,总量为15.73%,必须氨基酸总量为6.69%。[结论]水栉霉中脂肪酸和氨基酸的含量适于开发菌体饲料。

[Objective]The study aimed to further discuss the nutritional value of L.agardh,and the ingredients of fatty acid and amino acid in L.agardh were analyzed.[Method]Using gas chromatograph-mass spectrometer and automatic analyzer for amino acid.[Result]The main fatty acid components of L.agardh were hexadecanioc acid,octadecadienoic acid,oleic acid and octadecenoic acid,whose relative mass fraction were 17.238%,12.427%,20.666% and 24.121%,respectively,in which unsaturated fatty acid was 67.981%;there were 17 amino acids with a total amount of 15.73% and the essential amino acids accounted for 6.69%.[Conclusion]The contents of fatty acid and amino acid in L.agardh were suitable for developing bacterial feed.
