Penicillin G acylase electrode remains unchanged. After the electrode's anti-phospho performance literature, soaking and stirring in a 50 mmol/L phosphate buffer at room temperature for 150 hours retains the same sensitivity; the sensitivity drops after 300 hours to the original level. In Sichuan, electrodes without PEI processing reduced to 86% and 51% after 150h and 300h respectively. The content of penicillin G, using the enzyme electrode and iodometric method for determination of learning rejection values in different tank batches of penicillin fermentation broth and the fermentation time of penicillin G titer, results are shown in Table two. Mathematical statistical analysis was used, applying the rank sum test method for paired data significance testing. Results show that under conditions of mouth = 5%, there is no significant difference between the two methods of determination. Thus, the enzyme electrode is applicable for monitoring the penicillin fermentation process. Packed in a Chinese Journal of Pharmaceuticals 1989 Head Chi mold in the pharmaceutical industry magazine.
