从饵料、外界营养条件和离子变动的角度研究了夜光藻的营养动力学。结果表明,夜光藻与其饵料之间存在类似米氏方程的定量关系,外界离子变动可以影响夜光藻的生理活动,并提出了夜光藻赤潮形成的生化聚集机制。 |

Abstract: |
This paper, experimental work on the nutrient dynamics of Noctiluca scintillans from Qingdao Bay through its food, external nutrient conditions and ion conditions, showed that: Its growth rate depend to some extent on the external density of feed alga Platymonas sp. For a certain feed alga, there exists a highest growth rate of N. scintillans, the constant Km may display the rnetabolical relation between N. scintillans and feed alga. External ion conditions, and other environmental conditions, may affect population fluctuation by affecting the metabolism pathway of N. scintillans. The aggregation mechanism of N. scintillans red tide from the biological and physiological aspects are discussed. |
