Abstract
A device useful for growing aerobic microorganisms, particularly molds. The device employs a relatively small amount of water-reconstitutable medium that can be sealed in order to prevent desiccation and contamination of the medium yet still provide an adequate supply of air to the medium, by the use of a membrane underlying the medium, to support the growth of aerobic microorganisms.
