Microbiological Quality Control

Commercial firms look to ATCC to provide top-quality, fully characterized strains necessary to maintain the highest levels of product integrity and reputation.

Microbial Quality Control Strains

Repeated subculturing can be detrimental to quality control. Each passage carries the potential for contamination, drift, and mutation, taking your culture further and further from the parental genotype and phenotype. ATCC provides top-quality microbial reference materials to maintain outstanding quality control programs.

ATCC cultures are meticulously characterized and preserved to maintain quality control strains in a manner that permits reproducibility of results across time and among laboratories around the world. With ATCC Genuine Cultures®, customers can rely on:

  • Polyphasic identification and strain characterization
  • Proprietary systems for managing strain stocks
  • Meticulous propagation, preservation, and storage protocols
  • Robust quality systems

Whenever possible, ATCC balances traditional biochemical testing methods with automated phenotypic and genotypic analyses. This provides highly accurate identification across a wide array of microorganisms, and can help avoid the pitfalls of misidentification, painful recalls, and regulatory repercussions. Each vial contains a minimal passage descendant of the original material and has been handled only by ATCC.

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.
