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 value in Western France. Blooms of blue Haslea are also present outside oyster ponds and hence marine

Design of an artificial culture medium to optimize Haslea ostrearia biomass and marennine production [PDF]
Algal Research, 2020 The diatom Haslea ostrearia was first studied by Gaillon in the year 1820 because of the greening phenomenon of oysters in western France. This microalga has the capacity to produce and excrete a blue pigment, called marennine, that has antioxidant, anti-bacterial and anti-viral properties, with possible industrial applications related to aquaculture ...

Semi-continuous system for benthic diatom cultivation and marennine production
Algal Research, 2022 International audience ; The feasibility of culturing different blue Haslea species and strains in different types of photobioreactors (PBRs) was studied on the long-term (until 151 days). The different strains of blue Haslea were selected for their peculiarity to produce marennine-like blue pigments as a potential industrial high-value compound.

Benthic Diatom Blooms of Blue Haslea spp. in the Mediterranean Sea [PDF]
Marine Drugs, 2023 Blue Haslea species are marine benthic pennate diatoms able to synthesize a blue-green water-soluble pigment, like marennine produced by H. ostrearia Simonsen. New species of Haslea synthetizing blue pigments were recently described (H.

Prophylactic effect of Haslea ostrearia culture supernatant containing the pigment marennine to stabilize bivalve hatchery production [PDF]
Aquatic Living Resources, 2016 This paper explores the possibility of using the supernatant of Haslea ostrearia culture containing marennine, a natural microalgal pigment, as an antimicrobial in bivalve hatcheries. The blue mussel Mytilus edulis and the scallop Placopecten magellanicus were used as model animals, and the pathogenic marine bacteria Vibrio splendidus was used to ...

What Was Old Is New Again: The Pennate Diatom Haslea ostrearia (Gaillon) Simonsen in the Multi-Omic Age [PDF]
Marine Drugs, 2022 The marine pennate diatom Haslea ostrearia has long been known for its characteristic blue pigment marennine, which is responsible for the greening of invertebrate gills, a natural phenomenon of great importance for the oyster industry. For two centuries,

Moscow University Biological Sciences BulletinMarennine 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.

Blue Diatoms: Global Phenomenon of ˝Greening˝ in Shellfish and Record of Planktonic Haslea Species in the South Adriatic Sea [PDF]
Naše More (Dubrovnik), 2017 Diatoms are unicellular, photoautotrophic eukaryotic microorganisms, often forming colonies and can be found in most aquatic and moist terrestrial habitats. All known diatoms today have specific golden-brown pigment fucoxanthin that masks chlorophylls in
