Abstract: A method of making a flowable, dried agglomerated nutrient medium is provided. The method comprises introducing a nutrient component comprising a powdered nutrient, and an agglomeration liquid, into an agglomerator comprising a flow-through-type agglomeration chamber, wet-massing the nutrient component with the agglomeration liquid in the agglomeration chamber for a predetermined period of time to form agglomerated nutrient medium particles, and exposing the agglomerated nutrient medium particles to drying conditions for a period of time to form the dried, agglomerated nutrient medium. The nutrient component facilitates the growth of a microorganism. Compositions, articles, and kits comprising the flowable, dried agglomerated nutrient medium are also provided.

Abstract: A latent effervescent body comprising a selective agent is disclosed. A method of using the latent effervescent body in a method to selectively enrich a target microorganism is also disclosed. The method comprises providing a sample, a culture medium, and the latent effervescent body. The method further comprises contacting the sample, the culture medium, and the latent effervescent body under conditions to facilitate growth of the target microorganism. The method further comprises releasing the selective agent from the latent effervescent body. Optionally, the method includes detecting a microorganism.
