Table 1.
Notation for Model 1 (adsorption block).
| Terms | Meaning | Values used (units) |
|---|---|---|
| Variables (functions of time) | ||
| Bi | Uninfected density of bacterium i (i = 1, 2). B1 is permissive, B2 is nonpermissive | Initial values: 108 for each (/ml), except where specified |
| Pi | Density of free phage i (i = 1, 2). P1 is the wild type, and P2 is the mutant | Initial value 108 for P1; 1 for P2 (/ml), the latter at 8 min |
| Iij | Density of “infected” bacterium ij (phage i in bacterium j (i = 1, 2, 3; j = 1, 2)) | Initial values 0 (/ml) |
| Parameters | ||
| r | Bacterial growth rate | 0.02 (/min) |
| kij | Adsorption rate constant of phage i on cell j | ≤10−9 (ml/min) |
| δij | Rate constant of transition from infected bacterium (ij) to burst | 0.05 (/min) |
| bij | Phage number of progeny from Iij | 50 (individuals) |
| C a | Cycle length | 50 (min) |
| Dilutiona | Fraction of free phage transferred at cycle end | 0.1 |
