Abstract Haslea ostrearia is a marine diatom that synthesizes and releases marennine, a water-soluble blue-green pigment responsible for the greening of the gills and labial palps of bivalves. The present study evaluated the effect of different marennine concentrations (0, 0.5, 1.0 and 2.0 mg l− 1) on the behavior (valve opening), physiology ...

Among microalgae, the marine diatom Haslea ostrearia has the distinctive feature of synthesizing and releasing, into the surrounding environment, a blue-green polyphenolic pigment called marennine. The oyster-breeding industry commonly makes use of this natural phenomenon for the greening of oysters grown in the ponds of the French Atlantic coast. This

Influence du procédé de culture et de purification sur la quantité et la bioactivité de la marennine produite par Haslea ostrearia. [PDF]
La marennine est un pigment bleu hydrosoluble produit par la diatomée Haslea ostrearia, qui, dans un contexte de lutte pour la sécurité alimentaire, pourrait être valorisé comme probiotique dans les écloseries et nurseries de bivalves.

La diatomée Haslea ostrearia a longtemps été considérée comme le seul organisme apte à produire un pigment surnuméraire bleu nommé marennine, connu pour son rôle dans le verdissement des branchies des huîtres affinées dans les bassins ostréicoles ...

Marennine is a blue pigment excreted by the diatom Haslea ostrearia. This pigment is renowned for its antioxidant and antibacterial properties, which have raised research interest. The standard method for obtaining marennine is by harvesting the supernatant from cultures of H. ostrearia and applying a double ultrafiltration approach.

Marennine and marennine-like pigments produced by certain diatom species of the genus Haslea are unique water-soluble compounds with several valuable properties. The exact chemical structure of these pigments has not been fully elucidated, but data on the physical and chemical characteristics of marennines have been obtained primarily for H. ostrearia.

This study reports further information on “mareninne,” awater-soluble blue-green pigment synthesized by the diatom Hasleaostrearia, which is essential to the greening of maturing oysters inFrench production areas. The extraction process is reported, as well aspreliminary characterization of a partially purified marennine extract,including quantitative ...

Isolates of Haslea ostrearia containing different amounts of marennine have been investigated to elucidate the physiological role of this enigmatic blue pigment. Fluorescence analyses at room temperature and 77K showed that marennine is not involved in light-harvesting for either PS II or PS I. On the other hand, a light-shielding function of marennine

The marine diatom Haslea ostrearia was immobilized in a tubular agar gel layer introduced into a photobioreactor of original design with internal illumination for the continuous synthesis of marennin, a blue-green pigment of biotechnological interest. Marennin was produced for a long-term period (27-43 days) and the volumetric productivity was maximum (

SummaryDiatoms are one of the largest groups of primary producers in the oceans, yet despite their environmental importance little is known about their plastidial lipid biochemistry. It has been previously reported that Skeletonema species contain primarily C16/C16 and C20/C16 forms of mono‐ and digalactosyldiacylglycerol (MGDG and DGDG, respectively).
