The industrial production of 6-APA includes: (1) cultivation of Penicillium chrysogenum; (2) extraction with organic solvents, (3) crystallization; (4) penicillin hydrolysis by immobilized penicillin acylase; (5) extraction of phenyl acetic acid (AFA); (6) precipitation of 6-APA at its isoelectric point ( pH ~ 3,6). The scientific community and industry have interest in reducing the number of process steps required for 6-APA production. In this thesis a new method for 6-APA production is presented. In this process, the simultaneous production and hydrolysis of penicillin was carried out. The 6-APA was extracted from culture broth using ionic adsorbent. To demonstrate the technical viability of the process a suitable biocatalysts to perform...
