Zhou Yiyong , male, born in March, 1956，focusing on the study of environmental biochemistry.

He studied biochemistry in the department of biology, Wuhan University, graduating in 1982.，then worked on laccase in Hubei Institute of Chemistry until 1985, and on effects of heavy metals on the activities of enzymes involved in metabolism of active oxygen in plants in Huazhong Agriculture University, from which he gained his master degree in 1988.

Since then, he has been making efforts to incorporate the theories and methods of ecological enzymololgy with the researches of water pollution in Institute of Hydrobiology, from which he gained his doctorship in 1998.

He is aiming at the problems of water pollution, mainly from the biochemical view, in order to describe patterns of pollution and reveal the mechanisms underlying the stress processes. For several years, he has paid much attention on the problems closely related to eutrophication, including microbial extracellular enzymes, and regeneration of phosphorus as a key element limiting the productivity in water body, the results suggested the causative linkage between nutrient cycling and eutrophication. In short, eutrophication is a process, in which the decomposition of organic matter is accelerated.

He has published more than 50 papers.

The following questions are deeply concerned in the future:

How does nutrient enrichment interact with other stressors?

What are the functions of the major biochemical factors, such as key elements with different forms, extracellular enzymes, organic acids, humic substances and trace metals? How do they interact with each other?

What are the major mechanisms by which the microbial loop regulates the metabolism of freshwater ecosystems?

Is it possible to introduce the biochemical technology into the practice of remediation and purification of polluted water?
