Algicidal Bacteria in Plankton Communities: Resistance, Lysis and Heterotrophy (C01)

浮游生物形成复杂的群落，对全球初级生产作出重大贡献，并为海洋食物网提供燃料。本项目主要研究次生代谢物在复杂浮游生物群落结构中的中介作用。我们重点研究了能够裂解形成水华的藻类的溶解菌海藻科迪亚（Kordia algicida），并研究了它对浮游生物动力学的影响。藻类/细菌相互作用的调节和对海洋食物网的级联效应将在实验室和现场实验中解决。

Organisms in the plankton form complex communities that contribute substantially to global primary production and fuel the marine food web. This project focuses on the role of secondary metabolites as mediators of the complex plankton community structure. We focus on the lytic bacterium Kordia algicida that is capable of lysing bloom forming algae and investigate its influence on plankton dynamics. The regulation of algal / bacterial interaction and the cascading effects on the marine food web will be addressed in lab and field experiments.
