| Highly expressed condition | (LoTm) Cells were grown in Spizizen’s minimal medium (SMM) (C. Anagnostopoulos, J. Spizizen, J Bacteriol 81, 741, May, 1961) with vigorous agitation. The control culture was grown at 37 °C [SMMPr]. For growth at high or low temperatures, pre-cultures were grown at 37 °C, diluted to an OD578nm of 0.1 and subsequently transferred to 51 °C [HiTm] and 16 °C [LoTm], respectively. For the growth at high salinity, the salinity of the medium was adjusted by adding NaCl (5 M stock solution) to produce a final concentration of 1.2 M [HiOs]. |
| (M9stat) Cells were grown in M9 supplemented with glucose (0.3 %) at 37°C with vigorous shaking. The composition of the M9 minimal medium is (per liter): 8.5 g Na2HPO4.2H20, 3 g KH2PO4, 1 g NH4Cl and 0.5 g NaCl. The following solutions were individually sterilized and added (volumes per liter of medium): 1 ml 0.1 M CaCl2.2H2O, 1 ml 1 M MgSO4.7H2O, 1 ml 50 mM Fe-Citrate. Also added was 10 ml of a trace salts solution containing (per liter): 170 mg ZnCl2, 100 mg MnCl2.4H2O, 60 mg CoCl2.6H2O, 60 mg Na2MoO4.2H2O and 43 mg CuCl2.2H2O. Overnight cultures were diluted 2000-fold in pre-warmed M9 medium and samples were harvested during exponential growth [M9exp], at the transition phase [M9tran] and during stationary phase [M9stat]. |
| (Pyr) A 5 ml aliquot of LB medium was inoculated using frozen culture stocks. After a few hours growth at 37°C, precultures were prepared by inoculating 5 ml of M9 with this LB culture at several different dilutions usually ranging from 500- to 2000-fold. The dilution range was chosen so that one of these precultures had grown to and OD600 of 0.5 - 1.0 after overnight inculation. The chosen M9 medium precultures [at OD600 of 0.5 - 1.0] were used to inoculate 100 mL of M9 medium in 500 mL non-baffled shake flasks to an OD600 of 0.02. Filter-sterilized carbon sources were added separately to the medium M9 at following concentration: D-Glucose 3g/L[Glu], L-Malic acid 4.5g/L[Mal], L-Malic acid + D-Glucose 3 and 2g/L[M+G], D-Fructose 3g/L[Fru], D-Gluconate 4g/L[Glucon], Pyruvate 6g/L[Pyr], Glycerol 6g/L[Gly], Glutamic acid + Succinic acid 2 and 2g/L[G+S]. Where necessary, carbon source solutions were pH neutralized with 4 M NaOH prior to addition to the medium. Cells were harvested during the exponential growth phase. |
| (S2) Cells were grown in CH medium at 37°C and sporulation was induced by resuspension in warm sporulation medium as described by Sterlini and Mandelstam (J. M. Sterlini, J. Mandelstam, Biochem J 113, 29, Jun, 1969). The initiation of sporulation was designated T0, the time of resuspension. Samples were harvested at hourly intervals for 6 hours [S0 to S6] for the first set of experiments and for 8 hours [S0 to S8] for a second set of experiments. |

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]. |
