报告人简介

Lars Reier Bakken，professor at Faculty of Chemistry, Biotechnology and Food Science, Norwegian University of Life Sciences. He formed the NMBU Nitrogen group (http://www.nmbu.no/en/research/groups/nitrogen) together with Åsa Frostegård and Peter Dörsch. They have become a robust and productive group, breaking barriers in the research on physiology of microbial nitrogen transformations and the formation of NO and N₂O. They are well integrated into the international network of leading biochemistry and microbiology nitrogen research groups, hosting many guest researchers from US, Europe, China and Oceania (2-4 per year, 2-6 months each)
