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 ...

Isoprenoid biosynthesis in the diatom Haslea ostrearia [PDF]
Summary Diatoms are eukaryotic, unicellular algae that are responsible for c. 20% of the Earth's primary production. Their dominance and success in contemporary oceans have prompted investigations on their distinctive metabolism and physiology. One metabolic pathway that remains largely unexplored in diatoms is isoprenoid biosynthesis, which is ...

Bacterial community structure of the marine diatom Haslea ostrearia [PDF]
Abstract Haslea ostrearia produces a water-soluble, blue-green pigment, called marennine, with proven economic benefits (as a bioactive compound used to green oysters, which improves their market value). Incomplete knowledge of the ecological features of this marine diatom complicates its cultivation.

Complex Relationships between the Blue Pigment Marennine and Marine Bacteria of the Genus Vibrio [PDF]
Marennine, the water-soluble blue pigment produced by the marine diatom Haslea ostrearia, is known to display antibacterial activities. Previous studies have demonstrated a prophylactic effect of marennine on bivalve larvae challenged with a pathogenic ...

Sterol Biosynthesis in Four Green Algae: A Bioinformatic Analysis of the Ergosterol Versus Phytosterol Decision Point [PDF]
Animals and fungi produce cholesterol and ergosterol, respectively, while plants produce the phytosterols stigmasterol, campesterol, and β‐sitosterol in various combinations. The recent sequencing of many algal genomes allows the detailed reconstruction of the sterol metabolic pathways. Here, we characterized sterol synthesis in two sequenced Chlorella

Design of an artificial culture medium to optimize Haslea ostrearia biomass and marennine production [PDF]
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 ...

Effect of Precipitated Extracellular Marennine on Angiogenesis and Tumour Cell Proliferation [PDF]
Angiogenesis is a fundamental biological process involved in the formation of new blood vessels from the pre-existing vascular network. In addition to physiological processes, angiogenesis is also implicated in pathological conditions such as tumour ...

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

Isoprenoid biosynthesis in the diatoms Rhizosolenia setigera (Brightwell) and Haslea ostrearia (Simonsen). [PDF]
Isoprenoid biosynthesis in the widespread diatomaceous algae, Rhizosolenia setigera (Brightwell) and Haslea ostrearia (Simonsen), results not only in the production of diterpenoids, triterpenoids, and sterols but, unusually for diatoms, also in the production of sesterterpenoids. By using
