Understanding marine dissolved organic matter production: Compositional insights from axenic cultures of Thalassiosira pseudonana
Marine dissolved organic matter (DOM) is a key source of carbon and nutrients to microbial life in the oceans, but rapid biological utilization of labile DOM confounds its compositional characterization. In order to characterize potentially bioavailable DOM produced by phytoplankton, DOM from axenic cultures of Thalassiosira pseudonana cultivated in phosphorus (P) replete and low P conditions w...
متن کاملAdditional File 4. The identity of Thalassiosira pseudonana Previous concepts of Thalassiosira pseudonana Observations from diverse literature sources
Observations from diverse literature sources reveal that diatomists have more-or-less consistently viewed T. pseudonana as a small (less than 10 μm diameter) centric diatom with 0– 3 central area strutted processes, a relatively high number of marginal area strutted processes, and a labiate process situated roughly equidistantly between two marginal area strutted processes [1-7]. Ultrastructura...
متن کاملInfluence of CO2, nitrate, phosphate, and silicate limitation on intracellular dimethylsulfoniopropionate in batch cultures of the coastal diatom Thalassiosira pseudonana
We measured intracellular dimethyl sulfoniopropionate (DMSP) concentrations in nutrient-limited batch cultures of the coastal diatom Thalassiosira pseudonana. Under N, P, CO2, and Si growth limitation, intracellular DMSP concentrations decreased to low values during the exponential phase of growth and increased under nutrient limitation. The intracellular DMSP concentration increased exponentia...
متن کاملSpecific Selenium-Containing Macromolecules in the Marine Diatom Thalassiosira pseudonana.
Thalassiosira pseudonana Husedt (Hasle and Heimdal) clone 3H was grown in axenic culture in artificial seawater medium containing 10(-8) molar Na(2) (75)SeO(3). Biochemical distribution of radiolabeled Se was determined by solvent extraction techniques, gel filtration, and polyacrylamide gel electrophoresis. Of the total cellular Se, 51% was protein bound. Two soluble macromolecules of 21 and 2...
متن کاملPhylogenetic analysis of methionine synthesis genes from Thalassiosira pseudonana
Diatoms are unicellular algae responsible for approximately 20% of global carbon fixation. Their evolution by secondary endocytobiosis resulted in a complex cellular structure and metabolism compared to algae with primary plastids. The sulfate assimilation and methionine synthesis pathways provide S-containing amino acids for the synthesis of proteins and a range of metabolites such as dimethyl...
