3.1.13.1 | -999 |
- |
Following cell growth at 10°C by counting viable cells, rather than by turbidity, yields very similar growth rates. The doubling times are about 7 h for the wildtype strain and 15.5 h for the rnr mutant strain. |

3.1.13.1 | -999 |
- |
In LB medium, inactivation of the rnr gene impairs growth at 4°C, but not at 30°C (dispensability of RNase R). Other nucleases can perform its role under these conditions |

3.1.13.1 | -999 |
- |
Significant reduction of the growth rate at 10°C: the doubling time increased from 6 h in the wild-type strain to 16.5 h in the rnr mutant strain. |

3.1.13.1 | -999 |
- |
The expression of the rnr gene increases less than twofold after a 2-h cold shock in which the culture temperature is decreased from 30°C to 10°C. |
