Marennine, Promising Blue Pigments from a Widespread Haslea Diatom Species Complex
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 pigment, marennine. This pigment, responsible for the greening of oysters in western France, presents different biological activities: allelop...
متن کاملIsoprenoid biosynthesis in the diatoms Rhizosolenia setigera (Brightwell) and Haslea ostrearia (Simonsen).
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 13C and 2H isotopic labeling techniques followed by NMR and mass spectrometry, specific inhibition of meval...
متن کاملInfluence of irradiance and temperature on the iron content of the marine diatom Thalassiosira weissflogii (Bacillariophyceae)
The marine diatom Thalassiosira weissflogii (Grun.) Fryxell et Hasle was grown over a wide range of irradiances and temperatures in both NO3 and NH4-amended seawater containing high Fe. Maximum growth rates were not affected by N source, but the initial slope of the growth irradiance curve was significantly greater for the NH4-grown cells. Light-limited phytoplankton contained 4 times more Fe (...
متن کاملEffects of Current Velocity on the Physical Structuring of Diatom (Bacillariophyceae) Communities
Diatom-dominated periphyton communities growing under different current velocities on precleaned rock substrates were harvested from the Maumee River, Ohio, during the winter of 1980. Analysis of the initial stages of colonization using scanning electron microscopy revealed that the communities were compositionally very similar, but that diatom cell densities were more than three times as dense...
متن کاملMorphometric Asymmetry of Frustule Outlines in the Pennate Diatom Luticola poulickovae (Bacillariophyceae)
Side orientation of cells is usually ambiguous in unicellular organisms, making it impossible to separate components of directional asymmetry (DA) and fluctuating asymmetry (FA). However, frustules of the diatom Luticola poulickovae have biradially symmetric outlines, and their central areas bear ornamentation that is asymmetric across the apical axis. The goal of this study was to explore diff...
