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 کاملEvaluation of produced water toxicity from an oil maritime terminal through Skeletonema costatum toxicity tests
. Abstract: The liquid eftluent from an oil maritime terminal, with produced water as the main component, had its toxicity evaluated through toxicity tests with the diatom Skeletonema costatum. Two previously treated eftluent samples (eftluents A and B), were provided by PETROBRAS for the experiments. Both samples presented high salinity (67%0for eftluent A and 62%0for eftluent B) and low pH va...
متن کاملDifferential growth of Euplotes vannus fed fragmented versus unfragmented chains of Skeletonema costatum
The major food source of marine c~liates has traditionally been thought to consist of small nano-sized prey items (including diatoms), and bacteria. Larger prey, including chain-forming diatoms, have been considered important dietary items for certain ciliates, particularly larger benthic species, but may provide a source of nutrition for a wider range of ciliate species if they are first modif...
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%.
