Bacteriocin ‐like inhibitory activities of seven Lactobacillus delbrueckii subsp. bulgaricus strains against antibiotic susceptible and resistant Helicobacter pylori strains

In this study, anti‐Helicobacter pylori activity of seven Lactobacillus delbrueckii subsp. bulgaricus (GLB) strains was evaluated by four cell‐free supernatant (CFS) types. The GLB strains produced heat‐stable bacteriocin‐like inhibitory substances (BLISs) with a strong anti‐H. pylori activity and some neutralized, catalase‐ and heat‐treated CFSs inhibited >83% of the test strains. Bacteriocin‐like inhibitory substance production of GLB strains can render them valuable probiotics in the control of H. pylori infection.
