Table 1.
Metabolites identified in E. huxleyi cell extract by gas chromatography-mass spectroscopy (GC-MS) analysis. Cell number represents the smallest amount of the cells needed to detect the metabolites. 1, 2, 5, 10 and 20 correspond to 1.16, 2.32, 5.80, 11.6 and 23.2 × 106 cells, respectively. Metabolites with asterisk were overloaded in the samples of 23.2 × 106 cells.
