Haslea ostrearia-like diatoms:biodiversity out of the blue

, 2014
International audienceDiatoms are usually referred to as golden-brown microalgae, due to the colour of their plastids and to their pigment composition, mainly carotenoids (fucoxanthin, diadinoxanthin, diatoxanthin), which mask chlorophylls a and c.
