TABLE 6.
acrA::uidA expression in wild-type strain K60 and the phcA and rpoS mutant strains increased in the absence of a carbon source
| Bacterial strain (plasmid) | GUS activity (fmol MU released per cell per min) in BMM witha:
|
|
|---|---|---|
| Carbon source | No carbon source | |
| Wild-type K60 (pVOacrA) | 0.0474 (0.003390) | 0.210 (0.05370) |
| phcA (pVOacrA) | 0.0854 (0.010700) | 1.60 (0.20300) |
| rpoS (pDBacrA) | 0.0120 (0.000015) | 0.023 (0.00035) |

The carbon source added was 0.2% glucose. Assays were performed in triplicate, and the values in parentheses are standard errors. Significantly different values, as determined by Student's t test at a P value of <0.001 with a 95% confidence interval, are indicated by boldface type.
