Group of Microbial Process in Aquatic Environment

Group Leader: Zhu Guibin Laboratory: State Key Laboratory of Environmental Aquatic Chemistry

Group of Microbial Process in Aquatic Environment 

  Dr. Guibing Zhu, Alexander von Humboldt Research Fellow, the winner of National Outstanding Youth Science Funding, guest scientist of Max Planck Institute for Marine Microbiology, is currently a professor at the Research Center for Eco-Environmental Sciences, the Chinese Academy of Sciences (CAS). He received Ph.D from Harbin Institute of Technology, in 2006. At present, some of the specialized methods and novel results have been published (Nature Geoscience, The ISME Journal, Scientific Reports and Environmental Science & Technology). The total citation frequency is 1400 and the top times cited is 254.  

  Guibing Zhu has been working on the research of nitrogen cycle of wetlands and nitrogen pollution control for a long time, especially on the new type of cycle mechanisms of nitrogen like anammox. He has expounded the population structure characteristics, the distribution of hot spots and the contribution of nitrogen cycle of anammox in wetland ecosystem. He has attained important achievements in anammox process in freshwater ecosystem.  

Research interests: (1) Microbial process in aquatic environments; (2) Microbial nitrogen cycle.

Ubiquitous anaerobic ammonium oxidation in inland waters of China 

Guibing Zhu*, Yongguan Zhu, Shanyun Wang, Weidong Wang, et al 

  Our group have cooperated with Dr. Yongguan Zhu, to demonstrate the significant anammox reaction in rice rhizosphere soil in a micro scale (um/cm). Afterwards, in the typical anoxic/aerobic interfaces of freshwater ecosystems (riparian zones), we found the hotspots of anammox that can significantly reduce the release of N2O. Then we expanded the scope of the study, we collected 256 samples of 10 types from 40 regions, the result shows that anammox is ubiquitous in terrestrial aquatic ecosystems in China.  

  These results bring into question the validity of present estimates of N2O emissions from China (419 Gg N yr −1) and globally (6 Tg N yr −1). These inaccurate calculations are based on an overrated amount of N2O emissions from N-fertilizer application and inadequate land surface data. The findings of omnipresent and significant anammox activity in Chinese inland waters and wetlands demonstrates that the distribution and ecological consequence of anammox in terrestrial ecosystems is of major importance, and warrants recalculations of the global N budget to which China is considerable contributor. In other words, the N2O emissions in China, the most cycle model must include the key process parameters of anammox to improve the nitrogen balance.
