藻类对碘的吸收和利用已有不少研究,Fries观察到碘对多管藻(Polysiphonia)的生活是绝对必要的。Iwasaki观察到碘对紫菜某一阶段的生长有刺激作用。Pedersen观察到碘对水云等褐藻的生长是必要的。Wolery和Lewin观察到碘对长囊水云(Ectocarpus siliculosus)的生长是必要元素,不能用溴来代替,并且长囊水云
There have been many studies on the absorption and utilization of iodine by algae. Fries observed that iodine is absolutely necessary for the life of Polysiphonia. Iwasaki observed that iodine stimulates the growth of a stage of laver. Pedersen observed that iodine is necessary for the growth of brown algae such as water clouds. Wolery and Lewin observed that iodine is an essential element for the growth of Ectocarpus siliculosus and that it can not be replaced with bromine,
