Antimicrobial activity by cell-free supernatant (CFS) of the tested Lactiplantibacillus plantarum (LP) and Apilactobacillus kunkeei (ALK) strains against Paenibacillus larvae and Melissococcus plutonius. The data (mean ± SD; n = 3) were expressed as zone of inhibition-ZOI (mm). Different lowercase letters (a–d) in each row indicate significant differences (p < 0.05).
