Table II. Major fatty acids analyzed by GC-MS in P. tricornutum under three different growth conditions at the end of the CARS experiment, culture: Ctrl (at 93 h), LL (at 93 h), and NS (at 141 h).
Data are from analyses of algae obtained during the last of the three culturing occasions, and the second column shows sd values of extraction replicates (n = 3).
