What is strain purity testing, and how is it done?
Strain purity testing is the process of checking a growing Bacillus culture to ensure it is a match for the target strain. Testing can also confirm that there are no non-target organisms present in the culture.
Purity testing can be done in a multitude of ways. We have a variety of genomic methods at our disposal that allow for thorough, efficient testing of each Bacillus culture. Testing is conducted at several steps of the process, including:
- Seed bank
- Inoculation flask
- Fermentation tank
- Dried culture (finished product)
Monitoring the purity of the culture at multiple points allows us to catch and correct any potential errors as soon as possible and keep the process efficient.
Why is purity testing important?
There are many reasons why purity testing is important. Checking for non-target organisms and striving to produce the highest yield possible are just a couple. However, all the reasons center around one key element: consistency.
Consistency—in processes, end products, and measures of success—helps assure our customers that the DNA fingerprint of a strain we’ve grown matches that of their target strain. When you partner with us to grow and scale up your Bacillus strains, you can be confident in our entire process—purity testing included—as we use our expertise to help meet your unique goals and scale your business.
