The disclosure provides culture devices and methods for a microorganism in a sample. The devices include a base member, a cover sheet, an adhesive layer coupled to the base member or the cover sheet, and a cold water-soluble gelling agent disposed on the base member; wherein the devices are substantially optically transmissive when the gelling agent is hydrated with a clear liquid. Methods of use include detecting or enumerating microorganisms. The methods further provide for detecting a microorganism by detecting the presence or size of an abiogenic gas bubble in a culture device.
