Nitrogenous preference of toxigenic Pseudo-nitzschia australis (Bacillariophyceae) from field and laboratory experiments
Field and laboratory experiments were designed to determine the differential growth and toxin response to inorganic and organic nitrogen additions in Pseudo-nitzschia spp. Nitrogen enrichments of 50 mM nitrate (KNO3), 10 mM ammonium (NH4Cl), 20 mM urea and a control (no addition) were carried out in separate carboys with seawater collected from the mouth of the San Francisco Bay (Bolinas Bay), ...
متن کاملEffect of Salinity on Pseudo-nitzschia Species (bacillariophyceae) Growth and Distribution
Salinity varies widely in coastal areas that often have a high abundance of Pseudo-nitzschia H. Peragallo. Pseudo-nitzschia is abundant in Louisiana waters, and high cellular domoic acid has been observed in natural samples but no human illness has been reported. To assess the threat of amnesic shellfish poisoning (ASP), we examined the effect of salinity on Pseudo-nitzschia occurrence in the f...
متن کاملInter- and Intraspecific Community Structure within the Diatom Genus Pseudo-nitzschia (bacillariophyceae).
Pseudo-nitzschia-specific PCR primers (PnAll F/R) were designed to amplify a polymorphic region of the internal transcribed spacer 1 (ITS1) from at least 11 Pseudo-nitzschia species. The primers were used to generate environmental clone libraries from Puget Sound, Washington, and Vancouver Island, British Columbia, to confirm that the primers were specific for Pseudo-nitzschia and to determine ...

متن کاملLaboratory Analyses of Nutrient Stress and Toxin Production in Pseudo- nitzschia spp. from Monterey Bay, California
Here we present results from laboratory experiments using Pseudo-nitzschia spp. isolated from Monterey Bay, California grown under constant temperature and irradiance. We demonstrate substantial clonal variability and variable toxicity depending on harvest time and nutrients. We also show that Si limitation can directly affect photosynthetic performance and looks functionally like iron and nitr...
