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 ...

Typification of the first recognized blue pigmented diatom, Haslea ostrearia (Bacillariophyceae) [PDF]

Plant Ecology and Evolution, 2019
Background and aims – The blue pigmented diatom, Haslea ostrearia (Gaillon) Simonsen, which has been the material object for many physiological and ecological studies, was first described from oyster ponds in France as Vibrio ostrearius Gaillon; however,

Sterol Biosynthesis in Four Green Algae: A Bioinformatic Analysis of the Ergosterol Versus Phytosterol Decision Point. [PDF]

J Phycol, 2021
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

Effect of Precipitated Extracellular Marennine on Angiogenesis and Tumour Cell Proliferation [PDF]

Marine Drugs
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]

Marine Drugs, 2014
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

The cell cycle of phytoplankton: A review

Journal of the World Aquaculture Society, Volume 53, Issue 4, Page 799-815, August 2022., 2022
Abstract Phytoplankton play an enormously important role in ecology and serve as critical food for aquatic organisms. The phytoplankton population rapidly increases in number after continuous cell cycles. Thus, understanding the cell cycle of phytoplankton is fundamental to the aquatic ecosystem research.

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.
