RNA |

|
| Source name |
chemostat 0.51 h-1 repet4 3min
|
| Organism |
Lactococcus lactis |
| Characteristics |
strain: IL1402
treatment: µ0.51 rifampicin
time: 3 min
|
| Treatment protocol |
At T=0 rifampicin was added into the culture at a final concentration of 500 µg.mL-1 so as to block transcription, mRNA levels were followed during the next 20 minutes
|
| Growth protocol |
cultures were performed in chemically defined medium with low Branched-Chain Amino Acid concentrations. Chemostat cultures (growth rates of 0.51 and 0.11h-1) were isoleucine limited whereas isoleucine starvation occured progressively in batch cultures (grawth rates of 0.8, 0.38 and 0.04 h-1).

| Data processing |
Raw data were processed to access mRNA concentrations and were normalized to the mean intensity of the reference membrane (before rifampicin addition) for each batch. mRNA half-lives (t1/2) were calculated from the degradation rate constant (k), which corresponds to the slope of mRNA concentration logarithm as a function of time with the relation t1/2=ln(2)/k
