| Once harmful algal blooms (HABs) reach a desalination plant, they can cause significant operational issues and potential health concerns for consumers. These issues stem from two factors – first, the algal cells produce organic matter that can cause filter clogging and membrane fouling, and secondly, some cells produce toxic substances or taste and odor compounds. This chapter first explains the mechanisms for cellular release of organic matter, the types of matter that are produced, and the relative contribution of each type of matter to fouling mechanisms. It then describes the wide range of toxins that are produced by HABs, their mode of toxicity, and analytical methods for detecting them. While taste and odor compounds are non-toxic, they are included... |

| The marine dinoflagellate genus Dinophysis includes species that are the causative agents of diarrhetic shellfish poisoning (DSP). Recent findings indicate that some Dinophysis species are mixotrophic, i.e. capable of both autotrophic and heterotrophic nutrition. We investigated inorganic (and organic) carbon uptake by several species of Dinophysis in the Light and dark using the 'single-cell C-14 method', and compared uptake rates with those of photosynthetic Ceratium species and heterotrophic dinoflagellates in the genus Protoperidinium. Experiments were conducted with water from the Gullmar Fjord and from the Koster Strait (Swedish west coast). Nutrient-enriched phytoplankton from surface water samples were concentrated (20 to 70 mu m) and incubated at... |
