Exopolysaccharide production by the epipelic diatom Cylindrotheca closterium: effects of nutrient conditions.
During the stationary phase of a batch culture of the epipelic diatom Cylindrotheca closterium, accumulation of exopolysaccharides and intracellular carbohydrates was observed. When nitrogen was added to the culture in the stationary phase, growth was resumed and the accumulation of exopolysaccharides was delayed. This indicated that nitrogen depletion caused cessation of growth, and stimulated...

متن کاملTocopherols modulate extraplastidic polyunsaturated fatty acid metabolism in Arabidopsis at low temperature.
Tocopherols (vitamin E) are synthesized in plastids and have long been assumed to have essential functions restricted to these organelles. We previously reported that the vitamin e-deficient2 (vte2) mutant of Arabidopsis thaliana is defective in transfer cell wall development and photoassimilate transport at low temperature (LT). Here, we demonstrate that LT-treated vte2 has a distinct composit...
متن کاملFatty Acid Profile and Hydrocarbon Characterization of Nitzschia Closterium (w.sm.)
Lipid productivity is a critical variable for evaluating algal species for biodiesel production. The pennate diatom Nitzschia closterium (W. Sm.) isolated from the local water body of Madurai was cultivated in four different media (WCg, Csi, F/2 and Diatom medium) and screened for the presence of neutral lipid content using Nile red fluorescent dye. The relative abundance of lipid content was e...
متن کاملEffects of UVB radiation and salt stress on growth, pigments and antioxidative defence of the marine diatom Cylindrotheca closterium
During emersion, diatoms are exposed to sunlight (with UVB) on tidal flats, where the salinity may increase as a result of evaporation. In order to investigate whether a combination of UV radiation and desiccation would cause oxidative stress under such conditions, an experiment has been carried out with the diatom Cylindrotheca closterium. Cell division rates, photosynthetic efficiencies, pigm...
