报告内容摘要：

Human intervention has doubled the amount of reactive nitrogen added to soils in the last hundred years. This has seriously disrupted the biogeochemical flow of nitrogen leading to serious pollution problems such as eutrophication of freshwater and marine ecosystems, contamination of nitrate in drinking water and increased greenhouse gas production. An important means of removing reactive nitrogen species is denitrification but much is uncertain about how microbial communities in soil respond to changes in nitrate and other environmental factors. In this seminar I will describe our recent work studying what environmental factors determine the type and distribution of denitrification genes in soils and how this informs our understanding of nitrogen biogeochemistry.
