摘要

在100%、10%、1%、0.1%和0%(对照)的黑斯廷斯培养基上培养塔玛氏Gonyaulax tamarensis。“干净”和严重污染的沉积物都被使用。极低浓度(0.01% v/v)污染的淋洗液能轻微促进塔玛菌的生长;受污染的养分浓度越高,生长就越慢。来自“干净”沉积物的养分不能促进生长;在任何给定的浓缩营养液中,对生长的抑制都没有污染营养液中看到的那么大。

Effects of polluted and non-polluted sediments on the growth of Gonyaulax tamarensis.

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.
