摘要

Devices for the propagation or storage of microorganisms are described. Generally, the devices include first and second layers that are separable from each other. The first layer includes a gelling agent and microbial growth medium and the second layer comprising a galling agent. The devices further include an indicator and a corresponding inducer, each of which may be included in the first layer, second layer, or both.
