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

浮游生物中的有机体形成复杂的群落，对全球初级生产做出重大贡献，并为海洋食物网提供燃料。该项目的重点是次级代谢物作为复杂浮游生物群落结构的介质的作用。我们专注于裂解细菌Kordia algicida是能够溶解水华形成藻类，并调查其对浮游生物动态的影响。将在实验室和实地实验中讨论藻类/细菌相互作用的调节和对海洋食物网的级联效应。

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.
