Summary: | Objecive:To screen the fatty acid(FA) composition of 20 marine microalgae species,including seven Diophyceae,six Bacillariophyeae four Chlorophyceae,two Haptophyceae and one Raphidophyceae species.Methods:Microalgal cells cultured at the Korea Institute of Ocean Science & Technology were harvested during the late exponential growth phase and the FA composition analyzed.Results:The FA composition of microalgae was speciesspecific.For example,seven different species of Dinophyceae were composed primarily of C14:0,C16:0.C18:0.C20:4n-6.C20:5n-3 and C22:6n-3.while C14:0.C16:0,C16:1.C18:0.C20:5n-3 and C22:6n-3 were abundant FAs in six species of Bacillariophyceae.In addition,four Chlurophyceae,two Haptopkyeeae and one Raphidophyceae species all contained a high degree of C16:1 n-7[(9.2R-34.91)%and(34.48-35.04)%].C14:0[(13.34-25.96)%]and[(26.69-Z8.24)%],and C16:0[(5.89-29.15)%]and[(5.70-16.81)%].Several factors contribute to the nutritional value of microalgae.including the polyunsaturated FA content and n-3 to n-6 FA ratio,which could be used to assess the nutritional quality of microalgae.Conclusions:This study is the first comprehensive assessment of the FA composition and nutritional value of microalgae species in South Korea,and identifies the potential utility of FAs as species-specific biomarkers. |
