The lowest lipid content was measured in
Chlorella
(14.7%). Furthermore, they all contained a different n-3
PUFA profile.
Chlorella
contained mainly ALA (2.8 g/100 g biomass)
and could thus function as an alternative for flaxseed.
Nannochlor-
opsis
contained mainly EPA (4.0 g/100 g biomass), whereas
Phaeo-
dactylum
and
Isochrysis
contained next to EPA (2.8 g and 3.5 g/
100 g biomass, respectively) also DHA (0.3 g and 0.8 g/100 g bio-
mass, respectively). Next to EPA and DHA,
Isochrysis
also contained
a significant level of SDA (1.1 g/100 g biomass), which was hardly
observed in the other microalgae.
