Cell-cell communication of bacteria of the Roseobacter clade with other bacteria and algae (B04)

本项目将重点研究鞭毛藻原心藻（proocentrum minimum）和硅藻海藻（Thalassiosira rotula）与其藻微生物群的相互作用。无菌藻类培养物将接种玫瑰杆菌群D. shibae和P. inhibens模型细菌，以确定它们对藻类生长、代谢物产生和死亡的影响，并与无细菌培养物和天然藻类微生物群的培养物进行比较。此外，我们还将研究船贝产生的外膜囊泡及其作为DNA传递体的意义。

This project will focus on the interaction of the dinoflagellate Prorocentrum minimum and the diatom Thalassiosira rotula with their phyco-microbiome. Axenic algal cultures will be inoculated with the model bacteria of the Roseobacter group D. shibae and P. inhibens to identify their influence on growth, metabolite production, and death of the algae in comparison to bacteria-free cultures and to those harbouring the natural algal phyco-microbiome. Further, outer membrane vesicles produced by D. shibae and their significance as a transmitter for DNA will be studied.
