[Toxicity and toxin profile of the dinoflagellate Alexandrium tamiyavanichii and toxic mussels in Harima-Nada of Seto Inland Sea, Japan].
From October to November 2004, the paralytic shellfish poison (PSP)-producing dinoflagellate Alexandrium tamiyavanichii was observed at Harima-Nada, Seto Inland Sea at a maximum cell density of 4,960 cells/L. The wild cells of the dinoflagellate collected from the same seawaters, and cultured cells derived from them showed toxicity scores of 6.25-15.4 x 10(-4) and 2.7-3.5 x 10(-4) MU/cell, resp...
متن کاملEffect of multiple antibiotic treatments on a paralytic shellfish toxin-producing culture of the dinoflagellate Alexandrium minutum
Alexandrium minutum is one of several dinoflagellate species capable of producing paralytic shellfish toxins. Previous work suggests that toxin levels are influenced by a number of parameters, including dinoflagellate-associated bacteria. In the present study, a toxin-producing culture of A. minutum isolated from Anakoha Bay in the Marlborough Sounds of New Zealand was subjected to an antibioti...
متن کاملEffects of nitrate and phosphate on grazer-induced toxin production in Alexandrium minutum
Two strains of Alexandrium minutum were exposed to waterborne cues from copepod grazers in factorial combinations of nitrate and phosphate concentrations to evaluate the importance of grazer-induced paralytic shellfish toxin (PST) production under different nutrient regimes. In nitrate-rich treatments, the presence of waterborne cues from grazers resulted in significantly increased cell-specifi...
