c/t, cis/trans double bond; DHA, docosahexaenoic acid; n.d.: not detected. <LOQ, concentration under quantitation limit. X Superscript letter in a value for significant differences in a same lipid fraction among raw C1 and C2 composition (p < 0.05). The values are expressed at g FA/100 g DW (dry weight); C1 and C2 represent the two companies studied.
