bacteriocins

Objective. To study antimicrobial effect of extracellular metabolites of probiotic L. plantarum 8P-A3 strain on antibiotic-resistant Klebsiella pneumoniae and Acinetobacter baumannii isolated from infected wounds. Materials and Methods. Bacteriological methods: semiquantitative sector method for extracting opportunistic microorganisms from an infected wound; a method for the identification of the antimicrobial activity of metabolites in a liquid milieu; The identification of bacteria was implemented with the help of the MALDI-TOF Autoflex mass spectrometer (Bruker Daltonics, Germany).
