Abstract excerpt
A total of 44 spontaneous phage-resistant mutants were isolated from three commercial Lactobacillus delbrueckii strains by secondary culture and agar plate methods. Phenotypic characteristics related to their phage-resistance capacities, i.e. plaquing efficiency, phage-resistance stability, lysogeny and adsorption rates were determined. The morphological, biochemical (sugar fermentation patterns) and...
