Weihenstephan Microbial Strain Collection

The strain collection of the microbiology unit specializes on food borne bacteria and yeasts. These general collections are growing steadily due to isolates resulting from routine identification work of our service department and the development of FT-IR technology for the identification of microorganisms. The bacterial collection also contains many strains of food borne pathogens. In addition, three specialized collections have been established which form the basis of current research projects. Our collections harbor a total of about 7000 strains.

WSGeneral collection of bacteria: ca. 2500 strains
WSResearch collection of coryneform bacteria: ca. 1200 strains
WSYCGeneral collection of moulds and yeasts: ca. 1000 strains
WSLC Research collection of Listeria: ca. 1000 strains
WSBC Research collection of Bacillus cereus group:ca. 1000 strains
