Die Temperaturabhängigkeit des Wachstums vonPhaeocystis pouchetii (Haptophyceae) in Batchkulturen

Temperature dependence of growth in Phaeocystis pouchetii (Haptophyceae) in batch cultures

Abstract

Temperature dependent growth rates ofPhaeocystis pouchetii (Haptophyceae) were investigated in 5–1 batch cultures. The algae had been isolated from the German Wadden Sea area off Sylt. Microscopic cell counts and fluorescense measurements yielded similar results. The growth ofP. pouchetii reveals a typical optimum curve between 7 °C and 20 °C. Maximal growth rates, 3 divisions per day, were obtained at 15 °C. At 5 °C the algae cultures survived, but multiplication of the cells almost ceased. Results of the culture experiments correspond with observations made onPhaeocystis blooms at the German North Sea coast.
