Characterization of Temperate Bacteriophages of Bacillus subtilis by the Restriction Endonuclease Eco RI: Evidence for Three Different Temperate Bacteriophages

Abstract

Temperate bacteriophages of Bacillus subtilis were characterized according to host range and digestion of the bacteriophage genome by endonuclease Eco RI. The three bacteriophages, φ3T, SPO2, and φ105, were all heteroimmune, and the DNA digests showed dissimilar patterns by agarose-ethidium bromide gel electrophoresis.
