Description |
The USP <2021> test provides for the estimation of the number of viable aerobic microorganisms present in nutritional supplements of all kinds, from raw material components to final, finished products. This test provides for the estimation of the number of viable aerobic microorganisms present within a sample. The sample is typically diluted, plated, and then incubated. Microbial enumeration of the sample can be achieved by membrane filtration, plate, or multiple tube methods. This chapter provides procedures for the following tests:
-
Total Aerobic Microbial Count (TAMC)
-
Total Yeast and Mold Count (TYMC)
-
Enterobacterial Count (Bile-Tolerant Gram-Negative Bacteria)
