Nitrate Utilization by the Diatom Skeletonema costatum
Nitrate uptake has been studied in nitrogen-deficient cells of the marine diatom Skektowema costatum. When these cells are incubated in the presence of nitrate, this ion is quickly taken up from the medium, and nitrite is excreted by the cells. Nitrite is excreted following classical saturation kineffcs, its rate being independent of nitrate concentration in the incubation medium for nitrate co...
متن کاملChlorophyll Turnover in Skeletonema costatum, a Marine Plankton Diatom.
[(3)H]- and delta-[(14)C]Aminolevulinic acids were incorporated into the chlorophylls of Skeletonema costatum, a marine plankton diatom. In the stationary phase of growth, the tetrapyrrole-based pigments reached steady-state labeling after 10 hours. Under conditions of exponential cell division and chlorophyll accumulation, (3)H was rapidly lost from the labeled chlorophylls and was replaced wi...
متن کاملGenome Sequence of Marinobacter sp. Strain MCTG268 Isolated from the Cosmopolitan Marine Diatom Skeletonema costatum
Marinobacter sp. strain MCTG268 was isolated from the cosmopolitan marine diatom Skeletonema costatum and can degrade oil hydrocarbons as sole sources of carbon and energy. Here, we present the genome sequence of this strain, which is 4,449,396 bp with 4,157 genes and an average G+C content of 57.0%.
متن کاملIsolation and Physiological Characterization of a Novel Algicidal Virus Infecting the Marine Diatom Skeletonema costatum
Diatoms are a major component of the biological community, serving as the principal primary producers in the food web and sustaining oxygen levels in aquatic environments. Among marine planktonic diatoms, the cosmopolitan Skeletonema costatum is one of the most abundant and widespread species in the world's oceans. Here, we report the basic characteristics of a new diatom-infecting S. costatum ...
متن کاملCellular and extracellular production of carbohydrates and amino acids by the marine diatom Skeletonema costatum: diel variations and effects of N depletion
A detailed study was made of cellular and extracellular production of carbohydrates and amino acids by the marine diatom Skeletonema costatum (Grev.) Cleve during different growth phases. Batch cultures were run with a 14:10 h light:dark cycle in N-limited media at 2 different nutrient strengths. The exponential growth rate was 2.0 div. d–1, and balanced growth took place except for significant...
