TABLE 3.
Effect of peptide treatment on survival and phage production by a lambda lysogen
| Treatment (concn) | % Survival ± SD (no. of independent colonies) | Phage titer (no. of colonies tested) | Fraction of phagea |
|---|---|---|---|
| DMSO (0.29%) | 59.4 ± 7.7 (9) | 8.9 × 109 (4) | 1 |
| wrwycr (24 μM) | 69.1 ± 8.5 (15) | 1.7 × 109 (4) | 0.18 |
| wrwyrggrywrw (12 μM) | 70.7 ± 6.3 (6) | 1.2 × 109 (4) | 0.14 |
| wrwyar (24 μM) | 58.5 ± 5.7 (12) | 8.3 × 109 (3) | 0.9 |
a
Fraction of phages whose titers were determined in lysates from bacteria treated with peptides relative to those whose titers were determined in lysates from bacteria treated with DMSO.
