One consistent trend we see is clients struggling to hit their colony forming unit (cfu) specification, often seeing a lower overall yield than expected. We support clients with root cause analysis and have often traced the issue to input cultures having a lower potency then expected from the supplier’s CofA. If you are using input cultures sourced from a third party, we highly recommend verifying the potency of these cultures via testing, not just working off the supplier’s CofA. Often, as these cultures are sourced and moved through supply chains there is a decrease in potency from the supplier’s original CofA.
