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。

The growth of H. fusiformis was determined by weighting the fresh algae every two days and the photosynthetic oxygen evolution was assayed by a Clark-type oxygen electrode. To determine the contents of chlorophyll a and UV-absorbing compounds, methanol extracts from H. fusiformis were scanned from 250 to 750 nm. The concentration of chlorophyll a was calculated using the equation of Porra and the contents of UVAC per fresh mass were estimated by determining the ratio of UVAC to chlorophyll a according to Dunlap et al and multiplying the ratio of chlorophyll a content to fresh weight of the sample used.

羊栖菜的生长是通过每两天测量一次藻体的湿重来测定的，光合放氧是用Clark型氧电极测定的，为了测定藻体叶绿素a和紫外吸收物质的含量，从250 nm到750 nm对羊栖菜的甲醇提取液进行扫描，叶绿素a的浓度用Porra的公式计算，紫外吸收物质的计算是根据Dunlap的方法先计算紫外吸收物质和叶绿素a的比率，然后乘以每单位藻体叶绿素a的含量。

Compared with the related pheophytin, the maximum absorption bands of RE-pheophytin red shifted in Soret band and blue shifted in Q band.
