Response of the marine diatom Thalassiosira weissflogii to iron stress1
The coastal diatom Thalassiosira weissfogii responds to iron limitation with decreasing growth rate, decreasing quotas of cellular iron, and increasing rates of maximum short term uptake. Growth response to steady iron limitation can be modeled according to the equations of Droop and Monod. The cellular iron quota varies from about 2 to 25 x 1O-5 mol iron per liter-cell with increasing iron; th...
متن کاملCadmium-Containing Carbonic Anhydrase CDCA1 in Marine Diatom Thalassiosira weissflogii
The Carbon Concentration Mechanism (CCM) allows phytoplakton species to accumulate the dissolved inorganic carbon (DIC) necessary for an efficient photosynthesis even under carbon dioxide limitation. In this mechanism of primary importance for diatoms, a key role is played by carbonic anhydrase (CA) enzymes which catalyze the reversible hydration of CO2, thus taking part in the acquisition of i...
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 کاملIntegration of TiO2 into the diatom Thalassiosira weissflogii during frustule synthesis
Nature has inspired the design of complex hierarchical structures in the field of material science. Diatoms, unicellular algae with a hallmark intricate siliceous cell wall, have provided such a stimulus. Altering the chemistry of the diatom frustule has been explored to expand on the potential application of diatoms. The ability to modify the diatom in vivo opens the possibility to tailor the ...
متن کاملResponse of the Ubiquitous Pelagic Diatom Thalassiosira weissflogii to Darkness and Anoxia
Thalassiosira weissflogii, an abundant, nitrate-storing, bloom-forming diatom in the world's oceans, can use its intracellular nitrate pool for dissimilatory nitrate reduction to ammonium (DNRA) after sudden shifts to darkness and anoxia, most likely as a survival mechanism. T. weissflogii cells that stored 4 mM (15)N-nitrate consumed 1.15 (±0.25) fmol NO3 (-) cell(-1) h(-1) and simultaneously ...
