Effect of Extracellular Marennine produced by Haslea Ostrearia on the Blood Clams Tegillarca Granosa

Journal of Aquaculture and Fish Health
Marennine is a blue-green pigment produced by diatoms of the Haslea genus, one of which is Haslea ostrearia. This marennine pigment is water-soluble and confirmed to contain polyphenols and glycosides. There are two forms of marennine pigment: the intracellular form of marennine (IMn) and the extracellular form of marennine (EMn).

Influence du procédé de culture et de purification sur la quantité et la bioactivité de la marennine produite par Haslea ostrearia. [PDF]

Marennine is a water-soluble blue pigment produced by the diatom Haslea ostrearia. In the context of fighting for food security, this compound could be used as a probiotic in bivalve hatcheries and nurseries.

Effect of culture supernatant from Haslea ostrearia on the clearance rate and survival rate of adult Pacific oyster Crassostrea gigas infected with Vibrio aestuarianus

, 2021
The microalga Haslea ostrearia is known as a diatom with the peculiarity of producing a water soluble blue-green pigment called marennine. This pigment has antibacterial activities against pathogenic bacteria of bivalves produced in aquaculture.

Evaluating the effect of various treatments on the diatom Haslea ostrearia for achieving axenic cultures

Regulatory Mechanisms in Biosystems
Axenic microalgae cultures are needed for several applications: genetic research, chemical exploration, aquaculture, and the study of interactions between microalgae and bacteria. Eliminating bacterial contamination while preserving the vitality of microalgae remains a considerable challenge.
