The DSMZ accepts biological material for deposit which belongs to risk group 1 or 2

according to EEC Directive 2000/54/EC on the Protection of Workers from Risks Related to Exposure to Biological Agents at Work

or, in case of genetically engineered material, safety level S1 or S2 or class 1 or 2, respectively

according to the German Law Regulating Genetic Engineering or the EEC Council Directive 2009/41/EC on the contained use of genetically modified microorganisms

In any case it must be possible to store the biological material to be deposited by freeze-drying and/or storage in liquid nitrogen.
