| Highly expressed condition | (C30) Cellsgrown overnight on LB agar plates at 30°Cwere harvested and used to inoculate pre-warmed minimal medium at OD600 of 0.5 (D. Dubnau, R. Davidoff-Abelson, J Mol Biol 56, 209, Mar 14, 1971). After growth at 37°C with vigorous shaking, cells were diluted ten times in fresh pre-warmed minimal medium and samples were harvested after a period of 30 minutes [C30] , i.e. before maximal induction of competence, and after a period of 90 minutes [C90], i.e. when competence induction was maximal. |
| (GM+45) A culture of LB medium was inocualted from a frozen glycerol stock of B. subtilis. After few hours at 37oC when the culture was growing exponentially, this culture was used to inoculate M9 minimal medium at several different dilutions usually in the range of 500- to 2000-fold. The dilution range was chosen to ensure that at least one of these M9 precultures had reached an OD600 between 0.5 - 1.0 after overnight incubation. These precultures were then used to inoculate 2.5 L of M9 medium in a 3.1 L KLF bioreactor (Bioengineering AG, Wald, Switzerland) to a starting OD600 of 0.03 – 0.05. Condiions in the bioreactor were rigorously controlled as follows: temperature was controlled at 37 °C; the pH was maintained at exactly 7.2 by automatic titration with 2.0 M KOH and 2.0 M H2SO4, and the dissolved oxygen tension was maintained above 50%. In each nutritional shift experiment cells were grown on the single substrate until the OD600 reached 0.50, at which point the second substrate was added instantaneously (4 g/L L-malate or 3 g/L glucose). The nutrient shifts performed were from glucose to glucose+malate [GM] and from malate to malate+glucose [MG] (Buescher et al., accompanying paper). Cell growth during the course was monitored throughout the experiment by measuring OD600. |
