本文首次研究了镧－脯氨酸和镧－苯丙氨酸络合物对球等鞭金藻（Ｉｓｏｃｈｒｙｓｉｓｇａｌｂａｎａ）的影响，结果表明，两种络合物对球等鞭金藻细胞繁殖及叶绿素的合成有明显的促进作用，浓度范围为５－２０ｍｇ／ｄｍ３时，至第６天细胞数分别提高１０．８％～１７．２％，１１．５％－２０．５％（Ｐ＜０．０５）；叶绿素浓度分别提高３１．７％－３７．５％，４４．７％～４８．４％（Ｐ＜０．０５），其中以浓度为１０ｍｇ／ｄｍ３的实验组最高。镧的氨基酸络合物对球等鞭金藻的作用效果与镧相比是等同的。
In this paper, the effects of lanthanum-proline and lanthanum-phenylalanine complexes on Isochrysis galbana were studied for the first time. The results showed that the two complexes promoted the proliferation and chlorophyll of Isochrysis galbana (P <0.05). The number of cells increased by 10.8% -17.2% and 11.5% -20.5% at 6th day respectively when the concentration was 5-20mg / dm3 ), Chlorophyll concentration increased by 31.7% -37.5% and 44.7% -48.4%, respectively (P <0.05). The highest concentration of chlorophyll in experimental group was 10mg / dm3. The effect of lanthanum amino acid complexes on Isochrysis galbana is equivalent to that of lanthanum.
