evaluation of extracellular products and mutagenicity in cyanobacteria cultures separated from a eutrophic reservoir.the algal extracellular products (ecps) in three cultures of cyanobacteria species (anabaena, microcystis, and oscillatoria) dominating the eutrophic reservoir populations and their toxins have been investigated in the present work. using gas chromatography coupled with high-resolution electron-impact mass spectrometry (gc/ei-ms) and high performance anion-exchange chromatography (hpaec) techniques, more than 20 compounds were found in the algal culture (including cells and filtrates) extracts. ...200717391736
variation of geosmin content in anabaena cells and its relation to nitrogen utilization.the addition of the proper amount of ammonium to the culture medium containing nitrate as nitrogen source enhanced the growth rate of anabaena viguieri. the amount of geosmin produced by these cells varied with the concentrations of ammonium added. a negative correlation between the amount of geosmin produced and of the growth rate of cells was revealed. this was also found in cells grown on various forms of nitrogen sources. without supply of any nitrogen compound, this organism is capable of f ...19911814277
