A restriction map was constructed of the 37 kb genome of the temperate Lactobacillus delbrueckii subsp. bulgaricus bacteriophage lb539. Restriction analysis and Southern hybridization experiments detected variable levels of homologous regions among the genomes of lb539 and the L. delbrueckii reference phages LL-H (virulent) and mv4 (temperate).

Lactobacillus delbrueckii subsp. lactis (Lb. lactis) CNRZ 326 is widely used in the propagation of Lb. delbrueckii bacteriophages. In this study, evidence is presented that this strain possesses a restriction-modification (R/M) system. The mitomycin C-induced temperate bacteriophage lb539 has a reduced efficiency of plaquing (EOP) on CNRZ 326 cells (EOP =(More)
DNase activity was examined in the extracellular and subcellular fractions of six non-transformable strains belonging to Lactobacillus delbrueckii subsp. lactis (L. lactis) and Lactobacillus delbrueckii subsp. bulgaricus (L. bulgaricus) and compared with the activity present in Lactobacillus johnsonii NCK 65, a transformable strain of Lactobacillus. In the(More)
