A method of making a flowable, agglomerated nutrient medium is provided. The method comprises forming a nutrient medium composition by placing a powdered nutrient into a fluidized bed-type agglomeration chamber, flowing a fluidizing gas through the chamber, and contacting in the agglomeration chamber the powdered nutrient with an aerosol spray of an agglomeration liquid; and collecting the composition from the chamber. The nutrient component facilitates the growth of a microorganism. The composition formed by the method comprises a population of agglomerated nutrient medium particles and, optionally, nonagglomerated powdered nutrient. The population comprises at least about 30 weight percent agglomerated nutrient particles having an effective particle diameter of about 250-400 microns. Compositions, thin film culture devices, and kits comprising the flowable, dried agglomerated nutrient medium are also provided. |
