The dynamic experiments further show that 20% ethanol and 20% isopropanol are good for their high elution speed and large distribution ratio of 6-APA in the liquid phase etc.
Conclusions the usage of the new immobilized penicillin acylase reactor in the 6-apa production will result in a higher yield of 6-apa and lower loss of immobilized penicillin acylase.
