Lipid analysis was performed according to standard Methods 5520E. Samples were acidified with 1 mL.HCl per 40 mL. sample immediately after harvest. Extraction with n-hexane occurred over 4 h in a Soxhlet apparatus. Distillation of the solvent was performed in a Buchi R-200 rotavapor for 30 min at 70ºC. Measurements were performed in duplicate and averaged. Net digestion results were corrected for dilution due to 2N NaOH addition during digestion.
