The application of lactic acid bacteria (LAB) and bifidobacteria, which exhibit
therapeutic benefits, in dermatology, including treatment of skin infections specifically caused by Staphylococcus aureus, is new. The objectives of this study were to screen LAB and bifidobacteria for antimicrobial activity against S. aureus and to identify the antimicrobial compounds produced by LAB. In addition, the study aimed to inhibit the biofilm of S. aureus with extracellular extracts of LAB
