| Popis: |
The ciguatera-causing dinoflagellate Gambierdiscus toxicus Adachi et Fukuyo reached maximum abundance in the Florida Keys when the water temperature was ≈ 30°C; populations were over half maximum when temperature lay in the interval 27–30°C. In laboratory unialgal culture experiments, temperatures >29 and 1.4 × 1016 quanta.cm-2 · s-1 (≈ 11% of full sunlight). Under optimum combinations of the aformentioned parameters, growth rates > 0.5 division · day-14 could be sustained and led to unusually high yields in large scale cultures of up to 360 mg (dry weight) · 1-1. Cultures grown at 27°C were more toxic than those at 21°C (3515 ± 500 cells · MU-1 vs. 16536 ± 2400 cells · MU-1, sd). Cultures were also still capable of producing toxins at inhibiting high irradiance levels. |
