Best calibrated QC strains used in pharma industry for Growth promotion test microbiology

Pharmaceutical Microbiology: The 4 Best Calibrated QC Strains

In the pharmaceutical and medical device industries, we are asked to perform so many growth promotion tests (GPT) that often the use of ready-to-use, calibrated strains is more cost-effective… provided that you can find a good QC (Quality Control) strain supplier!

To assist you in this quest, we asked the SuperMicrobiologists (9,700 followers on the LinkedIn page) which calibrated strain suppliers they preferred.

Here are the 4  best quality control strains according to the SuperMicrobiologists.

If required, CRM strains available (reference name is BACuanti)

ielab environmental isolate (Reference materials produced from environmental isolates)

ielab offers a customized strain production service. You send them your endogenous strain, and they transform it into a ready-to-use lyophilized strain at the desired concentration. 

Strengths of ielab environmental isolate

  • Production time is usually around 1 month.
  • Ielab offers the possibility to store the isolated strains at (-70 ± 10ºC).
