Content of Chla,β-carotene and zeaxanthin of S. platensis grown in Se decreased, violaxathin, fucoxanthin, 19'-hexanoyloxyfucoxanthin and peridinin increased, Chla and Chlb of D. salina also decreased, but carotene increased, all pigments of D. zhanjiangensis increased except violaxanthin and 19'-hexanoyloxyfucoxanthin decreased. Effect of Ge on pigments of microalgaes were different in different algaes: Chla,β-carotene and zeaxanthin of S. platensis decreased, three other carotene increased, in D. salina, violaxanthin and lutein decreased, violaxathin, fucoxanthin and 19'-hexanoyloxyfucoxanthin increased, all pigments of D. zhanjiangensis increased except fucoxanthin and peridinin decreased; Chla,β-carotene and violaxanthin of Chlorella sp increased, but fucoxanthin and peridinin decreased.

暴露于硒中的钝顶螺旋藻（S.platensis）的叶绿素A、β-胡萝卜素和玉米黄素的含量都减少，岩藻黄素、19'-乙酰氧化岩藻黄素、多甲藻素和紫黄素的含量明显增加，盐生杜氏藻的叶绿素类也减少，但类胡萝卜素的含量则增加，湛江叉鞭金藻（D.zhanjiangensis）中除紫黄素和19'-乙酰氧化岩藻黄素有减少外，其它色素都增加；锗对四种微藻光合色素的影响也不尽相同，钝顶螺旋藻（S.platensis）的叶绿素A、β-胡萝卜素及玉米黄素含量减少，岩藻黄素、19'-乙酰氧化岩藻黄素和紫黄素的含量增加，盐生杜氏藻中除紫黄素和叶黄素有增加外，其它色素都减少，湛江又鞭金藻（D.zhanjiangensis）正相反，除岩藻黄素和多甲藻素有减少外，其它色素都增加，小球藻的叶绿素A、β-胡萝卜素和紫黄素增加较大，但岩藻黄素和多甲藻素则减少。
