Marennine, Promising Blue Pigments from a Widespread Haslea Diatom Species Complex [PDF]

Marine Drugs, 2014
In diatoms, the main photosynthetic pigments are chlorophylls a and c, fucoxanthin, diadinoxanthin and diatoxanthin. The marine pennate diatom Haslea ostrearia has long been known for producing, in addition to these generic pigments, a water-soluble blue

Harmful or harmless: Biological effects of marennine on marine organisms [PDF]

Aquatic Toxicology, 2019
Marennine is a water-soluble blue-green pigment produced by the marine diatom Haslea ostrearia. The diatom and its pigment are well known from oyster farming areas as the source of the greening of oyster gills, a natural process increasing their market ...

Investigating the action of the microalgal pigment marennine on Vibrio splendidus by in vivo 2H and 31P solid-state NMR [PDF]

Biochimica et Biophysica Acta (BBA) - Biomembranes, 2021
This work investigates the potential probiotic effect of marennine - a natural pigment produced by the diatom Haslea ostrearia - on Vibrio splendidus. These marine bacteria are often considered a threat for aquaculture; therefore, chemical antibiotics ...

Not only greening: The effects of marennine produced by Haslea ostrearia on physiological traits of three bivalve species

Aquaculture Reports, 2020
The marine diatom Haslea ostrearia is known for its ability to produce marennine, a blue-green water-soluble pigment, which is responsible for the oyster greening phenomenon in the French Atlantic Coast.
