Media Testing

As many culture-based procedures analyze products for microbial growth, it is essential that the quality control of the associated culture media is upheld using authenticated microbial control strains. ATCC provides various microbiological strains for use in routine media sterility and growth promotion testing, MIC assays, and the analysis of selective/differential media.
