The need to stabilize the bacterial community present in the cultures of the marine diatom Haslea ostrearia

, 2023
Abstract Objectives: Haslea ostrearia is a microalgae associated with the marrenine, a blue pigment known for its economic interest when it attaches to oyster gills. Complex to grow under axenic conditions, H. ostrearia probably needs its own bacterial procession to survive.

Haslea ostrearia-like diatoms: biodiversity out of the blue

, 2014
Diatoms 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.

Carbon fixation and carbonic anhydrase activity in Haslea ostrearia (Bacillariophyceae) in relation to growth irradiance

Photosynthetica, 2008
The metabolic pathway of primary carbon fixation was studied in a peculiar pennate marine diatom, Haslea ostrearia (Bory) Simonsen, which synthesizes and accumulates a blue pigment known as “marennine”. Cells were cultured in a semi-continuous mode under saturating [350 µmol(photon) m−2 s−1] or non-saturating [25 µmol(photon) m−2 s−1] irradiance ...
