Prokaryotic microbiomes of halophile and halotolerant microalgae

Microalgae are the primary producers of organic matter in reservoirs of various types. They serve as the base of food webs in the water ecosystems. The growth of algae is known to be influenced by the associated bacteria. The aim of this project is evaluation of the composition of prokaryotic communities associated with microalgae isolated from lakes and rivers with different salinities. A new dataset of sequences of V3-V4 region 16S rDNA resulted from the project, will be used to assess the diversity and structure of bacterial communities associated with algae under different salinities. The data can be applied for the study of interactions between prokaryotes and algae in associations. The obtained results are also promising for development of methods of handling the biotechnological processes involving commercially important cultures of algae.

微藻是各类水生环境中有机物的主要生产者，亦是水生生态系统食物网的基础。已有研究证实，藻类的生长会受到其共生细菌的影响。本项目旨在解析从不同盐度的湖泊与河流中分离得到的微藻所关联的原核生物群落组成。本项目产出了一套全新的V3-V4区16S rDNA序列数据集，将用于评估不同盐度条件下与藻类共生的细菌群落的多样性与结构。该数据集可用于探究共生状态下原核生物与藻类之间的相互作用关系。本研究所得结果还有望为开发涉及商业化养殖藻类的生物技术工艺提供理论支撑与技术参考。
