Fig. 4From: Enzyme-catalyzed biodegradation of penicillin fermentation residues by β-lactamase OtLac from Ochrobactrum triticiIn vitro biodegradation of penicillin V and penicillin G by OtLac. A HPLC analysis of penicillin V degradation by OtLac, the retention time of penicillin V and its product was 13.71 min and 6.77 min respectively. B HPLC analysis of penicillin G degradation by OtLac, the retention time of penicillin G and its product was 9.23 min and 5.89 min respectivelyBack to article page
