| Highly expressed condition | (B36) A fresh colony grown on an LB plate was used to inoculate 10 ml of LB and grown for 10 hoursat 30°C. This culture wasused to inoculate 10 ml of MSgg medium (S.S. Branda et al., J Bacteriol 186, 3970, Jun, 2004) and incubated with vigorous shaking. The cultures in MSgg were diluted to the same extent in 96 wells microtiterplates (5 μl for 1.5 ml of medium) and incubated without shaking at 30°C. Cells from the control cultures were harvested after 24 hours of incubation [BT]. Biofilms were harvested from 96 well plates after incubation for 36 hours [B36] and 60 hours [B60]. |

| (Cold) Cells were grown in a synthetic medium (J. Stülke, R. Hanschke, M. Hecker, J Gen Microbiol 139, 2041, Sep, 1993) with 0.2 % glucose as carbon source (Belitsky Minimal Medium/BMM) at 37 °C with vigorous shaking. Stress was applied to exponentially growing cultures at OD500nm of 0.4. Samples were harvested before stress [BMM]; after a rapid temperature up-shift from 37 °C to 48 °C [Heat]; after a temperature down-shift from 37 °C to 18 °C [Cold]. Ethanol stress was imposed by adding ethanol to a final concentration of 4 % (v/v) and cells were harvested 10 minutes after ethanol addition [Etha]. |

| Lowely expressed condition | (dia5) Diamide was added to an exponentially growing culture (OD600 approx. 0.6) at a sub-lethal concentration(0.5 mM) and growth continued at 37°C with vigorous shaking. Samples were collected 0, 5 and 15 minutes after diamide addition [dia0, dia5 and dia15]. |
| (Diami) Cells were grown in LB medium at 37°C. At OD540 of 0.3, the culture were divided into four subcultures and diamide 0.6 mM [Diami], paraquat 0.4 mM [Paraq], H2O2 0.1mM [H2O2] or no oxidative drug [Oxctl] were added to the medium. Samples were taken 10 minutes after addition |

| (M40t45) Cells were grown in LB medium at 37°C with vigorous shaking. An exponentially growing culture (O.D.600 approx. 0.25) was divided: one culture acted as the control [no mitomycin C , M0] while mitomycin was added to the second culture to a final concentration of 40 ng/ml [mitomycin, M40]. Samples were harvested at 0, 45 and 90 minutes after mitomycin addition [t0, t45 and t90]. |
| (MG+15) 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. |
| (Paraq) Cells were grown in LB medium at 37°C. At OD540 of 0.3, the culture were divided into four subcultures and diamide 0.6 mM [Diami], paraquat 0.4 mM [Paraq], H2O2 0.1mM [H2O2] or no oxidative drug [Oxctl] were added to the medium. Samples were taken 10 minutes after addition |
| (T3.30H) Anon-sporulating B. subtilis strain was grown in a modified M9 medium in batch culture (T. Hardiman, K. Lemuth, M. A. Keller, M. Reuss, M. Siemann-Herzberg, J Biotechnol 132, 359, Dec 1, 2007). Glucose was exhausted when the culture reached an OD600 of approx. 10 and this was designated T0 [T0.0H]. 7 samples were harvested at various times before glucose exhaustion [T-5.40H to T-0.40H] and 10 samples at various times after glucose exhaustion [T0.30H to T5.0H]. |
