镧-氨基酸络合物对球等鞭金藻的影响
Effects of lanthanum-amino acid complexes on Isochrysis galbana
-
摘要: 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(Isochrysis galbana)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。Abstract: The study on the effect of lanthanum-proline and lanthanum-phenylalanine complexes on Isochrysis galbana showed that these two complexes could distinctly enhance its cell reproduction and chlorophyll synthesis. When the concentrations of lanthanum-proline and lanthanum-phenylalanine were 5~20 mg/dm3, the cell numbers on the sixth day were increased by 10.8%~17.2% and 11.5%~20.5%,and the concentrations of chlorophyll by 31.7%~37.5% and 44.7%-48.4%,respectively (P<0.05),with an optimum concentration of 10 mg/dm3. The effect of lanthanum-proline and lanthanum-phenylalanine on Isochrysis galbans was the same as that of lanthanum.
