Abstract: The present disclosure provides a culture device for enumerating colonies of microorganisms. The device can comprise a base, a coversheet, and a nonporous spacer member disposed therebetween. The spacer member comprises an aperture that defines a growth compartment. Disposed in the growth compartment are a cold water-soluble gelling agent, a dry oxygen-scavenging reagent, a dry buffer system, and an effective amount of a dry carbon dioxide-generating reagent. The buffer system is selected such that, when the growth compartment is hydrated with a predetermined volume of deionized water, an aqueous mixture with a pH less than or equal to 6.35 is formed.

Abstract: A method of detecting a Salmonella microorganism is provided. The method includes the use of a selective growth medium, a first indicator system that is converted to a first detectable product by a Salmonella microorganism, and a second indicator system that is converted to a second detectable product by β-galactosidase enzyme activity. The method further comprises inoculating the growth medium and incubating the inoculated growth medium at a temperature higher than 40 degrees C.

Abstract: A device for culturing anaerobic microorganisms is provided. The device comprises a body comprising a waterproof base, a waterproof coversheet attached to the base, and a growth compartment disposed between the base and the coversheet. The growth compartment has a perimeter and an opening that provides liquid access to the growth compartment. A portion of the perimeter is defined by a waterproof seal. The portion includes >50% of the perimeter. A dry cold water-soluble gelling agent is adhered to the base in the growth compartment. A dry first oxygen-scavenging reagent is disposed in the growth compartment.

Abstract: A composition is provided for detecting a Salmonella microorganism in sample. The composition comprises at least one first selective agent that inhibits the growth of Gram-positive microorganisms, a first differential indicator system comprising at least one first differential indicator compound that is converted to a first detectable product by a Salmonella microorganism, and a second differential indicator system comprising a second differential indicator compound that is converted by urease enzyme activity to a second detectable product. Optionally, the composition may comprise a third differential indicator system comprising a third differential indicator compound that is converted by a β-galactosidase enzyme activity to a third detectable product. Methods of using the composition to detect a Salmonella microorganism are also provided.

Abstract: Devices for the propagation or storage of microorganisms are provided including a first layer that has a first portion of a surface of the first layer, to which a first water-swellable gelling agent comprising a first clay is affixed. The devices further include a second layer that is separable from the first layer and has a first portion of a surface of the second layer, to which a second water-swellable gelling agent is affixed. Methods for detecting and enumerating at least one microorganism in a sample are provided. The methods include providing a device, separating the first layer from the second layer, adding an aliquot of a sample containing at least one microorganism onto the first or second water-swellable gelling agent to form an inoculated device, laminating the first layer back to the second layer, and incubating the inoculated device. Kits and methods of making the devices are also provided.

Abstract: In one aspect, the present disclosure provides a device. The device includes a body comprising a waterproof base, a waterproof coversheet attached to the base, and a channel disposed between the base and the coversheet. The channel has a perimeter and an opening that provides liquid access to the channel. A portion of the perimeter is defined by a waterproof seal. A dry first oxygen-scavenging reagent and an indicator reagent for detecting sulfate reduction by a sulfate-reducing bacterium are disposed in the device between the base and the coversheet. The waterproof base comprises a plurality of open microcompartment structures facing the coversheet.
