Antimicrobial and antibiofilm activities of culture filtrates from Lactiplantibacillus plantarum isolated from traditional dairy products in Menoufia, Egypt

Postbiotics produced by L. plantarum exhibited strong antibacterial and antibiofilm activity against resistant bacterial strains. These results highlight the promising potential of LAB-derived metabolites as natural, safe, and effective alternatives for inhibiting biofilm formation and mitigating the growing threat of antibiotic resistance.
