摘要：

The extraction of Penicillin G (PG) from the filtered cultivation medium of Penicillium chrysogenum and its conversion into 6-amino penicillanic acid (6-APA) and phenyl acetic acid (PhA) at pH 8 was performed in a 10 1 Kuhni extractor during the production by means of penicillin-G-amidase immobilized in a liquid membrane carrier system (LM). 6-APA was enriched in LM, and the PhA returned to the cultivation medium. After electrocoalescence of LM, the 6-APA was converted into ampicillin with the same enzyme at pH 6, while the liquid membrane phase and enzyme were recycled and reused.
