Intracellular antibiotic resistance genes (iARGs) constitute the important part of wastewater ARGs and need to be efficiently removed. However, due dual protection intracellular DNA by bacterial membranes cytoplasm, present disinfection technologies are largely inefficient in iARG degradation. Herein, we for first time found that erythrosine (ERY, an edible dye) could degrade iARGs producing abundant 1O2 under visible light. Seven log antibiotic-resistant bacteria were inactivated within only 1.5 min, 6 completely degraded 40 min photosensitized ERY (5.0 mg/L). A linear relationship was established between ARG degradation rate constants concentrations photosensitizing system. Surprisingly, a 3.2-fold faster than extracellular observed, which attributed unique indirect oxidation induced 1O2. Furthermore, effective real other photosensitizers (including Rose Bengal Phloxine B) high yields also achieve efficient The findings increase our knowledge preference provide new strategy developing with yield, like photosensitizing, removal.

Recently, the emergence of multidrug-resistant bacteria due to misuse antibiotics has attracted attention as a global public health problem. Many studies have found that fermented foods are good sources probiotics beneficial human immune system. Therefore, in this study, we tried find substance for safe alternative treatment bacterial infection kimchi, traditional food from Korea.Antimicrobial activity and antibiofilm were assessed against (MDR) Pseudomonas aeruginosa using cell-free supernatants lactic acid (LAB) isolated kimchi. Then, UPLC-QTOF-MS analysis was performed detect substances responsible antimicrobial effect.The supernatant (CFS) strain K35 kimchi effectively inhibited growth MDR P. aeruginosa. Similarly, CFS combined with co-cultures produced significant inhibition biofilm formation upon testing. On basis 16s rRNA gene sequence similarity, identified Pediococcus inopinatus. As result inopinatus K35, curacin A pediocin detected.As it confirmed significantly reduced formation. may emerge potential source able help manage diseases associated antibiotic-resistant infections.
