Arthrospira platensis has high lipid and pigment (such as chlorophyll and carotenoid) contents and thus evaluated as an important resource in functional food production. The cell growth rate and pigment concentration of EM24 increased by approximately 1.2-fold than those of the wild-type strain (WT). Fluorescence intensity levels in EM24, which were quantified with a lipid triolein standard curve, also increased by approximately 1.5-fold than those in WT (62.9 mg/Lvs. 38.9 mg/L). The analysis of fatty acid profiles indicated that the gamma-linoleic acid level in EM24 increased by 1.5-fold than that in WT.
