Resarch on the Difference in the Growth and the Lipid Accumulation of Three Species of Phaeodactylum tricornutum
摘要
Abstract
[Objective] The reference for the selection of Phaeodactylum tricornutum species and the determination of its culturing technology was provided through the research on the difference in the growth and the lipid accumulation of three species of Phaeodactylum tricornutum from different places. [Method] The capability in the growth,the lipid accumulation and the carbon chain composition of main fatty acid of three species of Phaeodactylum tricornutum :QEAC501 ,QEAC503 and QEAC504,in laboratory condition was compared. [Results] The results showed that all the three algal species under f/2 batch cultivations had not obvious differences in growth speed and also did not accumulate a large amount of lipid material due to the supplement of sufficient nutrition. Under the condition of less nutrition ,all of them would be induced to obviously accumulate lipids especially for the formation of triacylglycerols. The analysis result indicated that the ability in the triacylglycerols accumulation was significantly difference among three species but there was not significant difference in the composition of fatty acid chain length among three species,which fatty acid was consisted of C -16 in general. [ Conclusion] Attention to the selection of the species of mi-croalgae with the accumulation of high - fat should be paid and the environmental condition of nutritional deficiency was established for the induction of the fat accumulation in it.关键词
