Abstract

127 strains of bacilli sensitive to different phages of Bacillus subtilis were isolated from the soil of Moscow and its country-side. In 6 strains, restriction and modification systems were discovered which differed from these previously described for Bac. subtilis BsuR system. Two strains has identical restriction-modification systems, and one strain possessed two different systems. Using DNA from all 6 strains, it was possible to transform competent cells of Bac. subtilis RUB834. Two of these 6 strains could serve as recipients in transformation and transfection experiments.
