TABLE 2.
Effect of the HNL3 mutation on expression of hepA::luxAB
| Strain | Luminescence valuea after nitrogen  stepdown at time: | |
|---|---|---|
| 0 h | 10 h | |
| DR1069 | 1.6 ± 0.1 | 210.4 ± 1.8 | 
| HNL3 | 0.3 ± 0.1 | 6.7 ± 0.3 | 
| CPB7084 | 0.4 ± 0.1 | 11.0 ± 0.6 | 
Values presented are means ± standard errors of the means of relative units of luminescence from triplicate readings from one of three experiments, all of which produced similar results.
