中国科学院热带海洋生物资源与生态重点实验室 副主任

（海洋微生物被膜学科组责任研究员 xxwang@scsio.ac.cn）

研究兴趣与领域

主要从事微生物生理代谢与环境适应机制的研究。本学科组以海洋微生物和模式微生物为研究对象，关注毒素-抗毒素系统及原噬菌体等水平基因转移元件在环境适应性中的功能和调控，并系统阐释这些水平基因转移元件在环境胁迫条件下的调控通路。研究，有望从细菌的自身代谢调控中找到新的关键调控因子作为靶点，为抗药性细菌的抑制提供有效途径。  

代表性工作简介

 主要从事微生物的环境适应机制研究。近年来，围绕模式微生物和海洋微生物基因组中的原噬菌体、基因岛等可移动遗传元件和毒素-抗毒素系统，深入解析了原噬菌体和基因岛的转移过程及环境效应，鉴定出多个新类型的毒素-抗毒素系统并阐述其生理功能，揭示海洋微生物通过形成生物膜抑制金属腐蚀并抵抗污损生物新机制。这些研究有助于深入了解基因的水平转移在微生物适应性进化中的作用及开发通过海洋生物膜进行防腐的生物制剂具有重要的理论和现实意义。
