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.

A method of making a flowable, dried agglomerated microbiological nutrient medium, the method comprising:
- introducing a nutrient component comprising a powdered nutrient, and an agglomeration liquid, into an agglomerator comprising a flow-through-type agglomeration chamber;
- wherein the nutrient component facilitates the growth of a microorganism selected from the group consisting of a bacterium, a yeast and a mold;
- wherein the agglomeration liquid is introduced as an atomized spray;
- 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;
- and
- isolating a subpopulation of the particles having a size distribution range being about 149 microns to 1000 microns,
- wherein the subpopulation of the particles having a size distribution range being about 149 microns to 1000 microns is a second subpopulation, and further comprising a step of isolating a first subpopulation having a particle size distribution range of about 105 microns to about 2000 microns.
