The Chair for Microbial Ecology is led by Siegfried Scherer. (Department of Biosciences, Wissenschaftszentrum Weihenstephan). The Chair for Microbial Ecology is associated to ZIEL Research Center for Nutrition and Food Sciences 

Fundamental research concentrates on the ecology and molecular genetics of food borne pathogens. Several research groups in the department work on Listeria monocytogenes, Bacillus cereus, Salmonella enterica, Yersinia enterocolitica and enterohemorrhagic Escherichia coli.

Applied research is performed in close cooperation with the food industry, with a focus on the characterization of food borne microbes, including identifiction of bacteria and yeasts, description of novel taxa and analysis of the biodiversity of food borne microbial consortia.

The Department of Microbiology runs a microbial diagnostics unit, connected with a consulting service for the food industry with respect tp prevention and analysis of microbiological quality assurance problems.
