Bacterial infection is recognized as one of the biggest global health threats, causing millions of people's death every year(Wang et al., 2020). Traditional antibiotics-based therapies have been widely utilized to control this issue(Kohanski et al., 2010); however, their excessive use leads to the emergence of antibioticresistant bacteria, endangering to human health(Levy and Marshall, 2004).
