Bacteriophage Sp10 Infection of Bacillus Subtilis

Initial phenotypic characterization, methods of phage propagation, and complementation studies were performed with phage SP10 and SP10c, a clear plaque mutant derived from SP10. A propagation scheme was developed to generate high titer lysates of Bacillus subtilis W23. Phage production was analyzed in single-burst growth experiments and protein profiles were generated with PAGE-SDS. Analysis of the profiles in tube and/or slab gels revealed altered banding patterns with phage-infected versus uninfected cells. While no viral-coded nonstructural proteins were detected with this technique, five bands were assigned as viral structural proteins as evident in phage-infected cells
