The fermentation process entails production of Penicillin G (PenG), a precursor, which is enzymatically hydrolyzed to form 6-aminopenicillanic acid (6-APA). This compound is then enzymatically reacted with p-hydroxyphenyl methyl ester (PHPGME) to form amoxicillin, as shown in Figure 1 (Nunes et al. 2020).
