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,

Optimization of the growth and marennine production by the diatom Haslea ostrearia in photobioreactor

Algal Research, 2021
The benthic diatom Haslea ostrearia which has the capacity to excrete a blue pigment called marennine remains a challenging organism to culture in a photobioreactor (PBR).

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

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.

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-

Effect of marennine on the rearing medium and microbiota of Mytilus edulis larvae and its protective effect after exposure to the pathogenic Vibrio splendidus

Journal of Applied Aquaculture, 2023
Opportunistic pathogens have been associated with yield-limiting factors in bivalve hatcheries. Numerous natural compounds are being investigated for their beneficial effects and potential to enhance larval resistance without requiring antibiotics.

The blue diatom Haslea ostrearia from the Indian Ocean coast of South Africa, with comparative analysis of Haslea organellar genomes

Frontiers in Marine Science, 2022
Haslea ostrearia represents the model species of blue diatoms, a cluster of benthic marine species all belonging to the genus Haslea, noticeable for producing a blue pigment called marennine famous for its greening activity on the gills of bivalves but ...

Effect of the blue pigment produced by the tropical diatom Haslea nusantara on marine organisms from different trophic levels and its bioactivity

Aquaculture Reports, 2020
Marennine is the blue-green pigment produced by the temperate ubiquiste marine diatom Haslea ostrearia. This pigment is water-soluble and excreted in seawater during H. ostrearia growth and ageing.
