    • 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.
    • 提供了制备可流动的附聚营养培养基的方法。 所述方法包括通过将粉状营养物放入流化床型附聚室中形成营养培养基组合物,使流化气体流过所述室,并使所述粉末状营养物与附聚液体的气溶胶喷雾接触; 并从室收集组合物。 营养成分促进微生物的生长。 通过该方法形成的组合物包含聚集的营养培养基颗粒群和任选的非团聚的粉状营养物。 群体包含至少约30重量%的有效粒径为约250-400微米的附聚营养颗粒。 还提供了组合物,薄膜培养装置和包含可流动,干燥的附聚营养培养基的试剂盒。

    • 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.
    • 提供了制备可流动的,干燥的附聚营养培养基的方法。 该方法包括将包含粉末状营养物和附聚液的营养成分引入包含流通型附聚室的附聚器中,将附聚液中的营养成分与附聚室湿式预定一段时间 以形成附聚的营养培养基颗粒,并将附聚的营养培养基颗粒暴露于干燥条件下一段时间以形成干燥的聚集的营养培养基。 营养成分促进微生物的生长。 还提供了包含可流动,干燥的附聚营养培养基的组合物,制品和试剂盒。
