科研团队简介

Brief introduction of Institute of Environmental Microbiology

金属是生物有机体生存最基本、不可替代的元素,对研究生物进化具有一定的指导意义。在地球的历史演变过程中金属的形态及生物可利用性发生了巨大的改变。大氧化事件(Great oxidation event)导致环境中铜和锌的生物可利用性增强,而铁的生物可利用性却减弱。为了适应地球环境的变化,细菌不得不采用其他的机制维持自身营养元素的平衡。且铜和锌可通过攻击铁硫簇以产生抗菌特性,而为了抵御原生动物的捕食,细菌需要铜锌等金属抗性系统,以及其他能够增强铁硫簇摄入的机制,这些机制反而成为病原菌重要的毒力因子,从而增加病原菌对人类健康的威胁

团队于20169月成立,共发表SCI期刊论文15篇。课题组长2017年入选福建省百人计划,课题组目前在职博士后2名(其中一名外籍),科研助理2名,指导博士生2名(外籍)和研究生3名。

The Great Oxidation Event (GOE) significantly changed the bioavailability of soft metals such as zinc (Zn) and copper (Cu), what posed not only an opportunity, but also a challenge for all organisms. To ensure their own survival, prokaryotes developed mechanisms for Zn2+ and Cu+ homeostasis while eukaryotes that evolved later, when Zn/Cu concentrations raised, invented totally new Zn and Cu binding structures not present in prokaryotes. In contrast to prokaryotes, eukaryotic cells are able to accumulate Zn2+ in the intracellular organelles and utilize stored Zn2+ for many biological processes depending on the cell specialization. In case of macrophages, Zn2+ and Cu+ can be used for bacterial killing, bacteria through attacking Fe-S clusters needed in many vital enzymes. We hope we will inform regulatory agencies in the government concerned with public health with our results to ensure the public can be protected and legislative measures be taken at appropriate times.

Team was established on Sep of 2016, has already published at least 15SCIarticles. Pro. Rensingwas one of “100 talents” from Fujian province, we have 2 postdocs (one from Tunisia), 2 research assistants, 2 PhD students (international students) and 3 master students.
