Effects of patA, puuA, and puuP genes on the putrescine production. The amount of putrescine in the culture supernatant of the strains KT148, KT152, KT153, KT154, and KT162 grown in LB medium supplemented with 100 μg/mL of ampicillin for 48 h. When the OD600 reached 0.4, 0.03 mM IPTG was added. ***, p < 0.001; ns, not significantly different. Data shown are averages ± standard deviations, and culture experiments were performed in triplicate
