Characterization of the bacteriophage adsorption inhibiting material from Bacillus pumilus

Four distinctly different lytic bacteriophage systems for the organism Bacillus pumilus have been defined in this laboratory. Lysogenic bacteriophage and bacteriophage for B. pumilus isolated by Smith (1952.) were not available. The purpose of this project was to determine the nature of the bacteriophage inhibiting substance from the organism and to compare the effect of the inhibiting material on the different bacteriophages.
