Departments
In addition to the research departments ''Microbial Ecology and Diversity Research'' and ''Microbial Genome Research'', the eight departments of the DSMZ include the collection departments ''Microorganisms'', ''Bioresources for Bioeconomy and Health Research'', ''Human and Animal Cell Lines'' and ''Plant Viruses'' as well as the departments ''Services'' and ''Bioinformatics and Databases''.
The establishment of independent junior research groups (as of 2021: ''VirusInteract'' (interactions of plant viruses with their hosts) and ''Microbial Biotechnology'') provides qualification opportunities for young scientists conducting research on selected, current topics.
