Diatom artificial medium (DAM): a new artificial medium for the diatom Haslea ostrearia and other marine microalgae [PDF]

open access: yesJournal of Applied Phycology, 2007
Artificial media are used in physiological studies of microalgae to maintain consistent conditions from one experiment to another and these media must be adapted to the needs of the organism studied. The artificial medium, in this case named diatom artificial medium (DAM), was designed to maintain long-term cultures of Haslea ostrearia and 19 other ...

THE QUANTITATIVE ISOLATION OF 'INSOLUBLE ORGANIC MATTER' (IOM) FROM SEDIMENTS AND BACTERIA, AND ITS ATTEMPTED DISSOLUTION USING THE IONIC LIQUID l-ETHYL-3- METHYLIMIDAZOLIUM CHLORIDE-ALUMINIUM (HI) CHLORIDE [PDF]

open access: yes, 2000
Organic matter which is insoluble in common solvents and non-oxidising acids often comprises the quantitatively most important fraction of organic matter in sediments. This operationally defined material is usually simply termed 'insoluble organic matter'

Investigating the action of the microalgal pigment marennine on Vibrio splendidus by in vivo 2H and 31P solid-state NMR

open access: yes, 2021
This work investigates the potential probiotic effect of marennine - a natural pigment produced by the diatom Haslea ostrearia - on Vibrio splendidus. These marine bacteria are often considered a threat for aquaculture; therefore, chemical antibiotics ...

Cell size-based, passive selection of the blue diatom Haslea ostrearia by the oyster Crassostrea gigas [PDF]

open access: yesJournal of Molluscan Studies, 2017
International audience ; Pre-ingestive selection has been identified as a feeding mechanism of oysters that may influence their uptake of particles and microalgal cells. Oysters can feed specifically on the pennate diatom Haslea ostrearia, which produces the blue pigment marennine that is responsible for the greening of oysters.

Carbon fixation and carbonic anhydrase activity in Haslea ostrearia (Bacillariophyceae) in relation to growth irradiance

open access: yesPhotosynthetica, 2008
The metabolic pathway of primary carbon fixation was studied in a peculiar pennate marine diatom, Haslea ostrearia (Bory) Simonsen, which synthesizes and accumulates a blue pigment known as “marennine”. Cells were cultured in a semi-continuous mode under saturating [350 µmol(photon) m−2 s−1] or non-saturating [25 µmol(photon) m−2 s−1] irradiance ...

Influence de l'adsorption d'alginates sur les propriétés de membranes organiques d'ultra et de microfiltration [PDF]

open access: yes, 2000
Les applications potentielles des cultures de microalgues et cyanobactéries en dépollution d'effluents dans des photobioréacteurs à membrane souffrent de performances limitées par un colmatage de l'élément filtrant dû en grande partie aux ...

Seasonal fouling by diatoms on artificial substrata at different depths near Piran (Gulf of Trieste, Northern Adriatic) [PDF]

open access: yes, 2005
Seasonal fouling by diatoms was studied in the heavily polluted and eutrofied area near Piran in the Gulf of Trieste. Concrete plates (50 x 50 cm) were placed at l m, 3 m and 7 m depths, with the fouling observed monthly for one year, from March to ...

Preliminary metabolomic approach on the bacterial structure community of Haslea ostrearia [PDF]

open access: yes, 2016
The marine diatom Haslea ostrearia [1] produces a water-soluble blue-pigment named marennine [2] of economic interest. But the lack of knowledge of the ecological conditions, under which this microalga develops in its natural ecosystem, more especially bacteria H.
