Fire blight is a disease caused by Erwinia amylovora. For the limited effectiveness of copper products and the new regulations for the sustainable use of pesticides, biological control is considered a good alternative for the control of fire blight. Therefore, this thesis focuses on the research of lactic acid bacteria strains as biocontrol agents of fire blight. Three out of one hundred strains, which were identified as Lactobacillus plantarum TC54, TC92 and PM411, were selected by their ability to inhibit E. amylovora infections in different performed assays. A multivariate statistical analysis, combining different phenotypic and genotypic properties, determined that strains TC92 and PM411 were good candidates as biocontrol agents. Finally, the combination of lactic acid and strains TC92 and PM411 was used to increase the biocontrol efficacy and reliability in the biocontrol of fire blight
