Which are fatty acids of the green alga Chlorella?

Fatty acid composition of three species of Chlorella were studied under conditions of photoautotrophic and heterotrophic cultivation, nitrogen starvation, and outdoor in a photobioreactor. The composition 14:0, 16:0, 16:1, 16:2, 16:3, 18:0, 18:1, 18:2, α-18:3 is confirmed for Chlorella. Fatty acids with 20 carbon atoms and four or five double bonds are considered not originating from Chlorella. Other exceptions of this composition are interpreted as mixed algal culture, bacterial contamination or impurities.
