Cultures of Gonyaulax tamarensis were grown on Hastings medium based on 100%, 10%, 1%, 0.1% and 0% (control) of seawater elutrients of bottom sediments. Both "clean" and heavily polluted sediments were used. Very low concentrations of polluted elutrients (0.01% v/v) slightly enhanced the growth of Gonvaulax tamarensis; greater concentrations of polluted elutrient depressed growth. Elutrient from "clean" sediments did not enhance growth; the depression of growth at any given elutrient concentrate was not as great as that seen with the polluted elutrients.
塔玛亚历山大藻（Gonyaulax tamarensis）的培养是在基于底部沉积物海水洗脱液的100%、10%、1%、0.1%和0%（对照）的黑斯廷斯培养基上进行的。使用了“清洁”和重度污染的沉积物。极低浓度的污染洗脱液（0.01% v/v）略微促进了塔玛亚历山大藻的生长；更高浓度的污染洗脱液则抑制了生长。“清洁”沉积物的洗脱液没有促进生长；在任何给定洗脱液浓度下生长的抑制程度都不如污染洗脱液那么大。
