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. |
(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]. | |
(G135) Purified spores were obtained by growing cells in DSM medium (P. Schaeffer, J. Millet, J. P. Aubert, Proc Natl Acad Sci U S A 54, 704, Sep, 1965) at 37°C for 48 hours after which they were washed ten times in ice cold distilled waterover a period of 5 days. Purified spores were heat activated at 70°C in Tris 10 mM pH8.4 and germination was initiated by the addition of L-alanine 10 mM (A. Moir, J Bacteriol 146, 1106, Jun, 1981). After incubation for one hour at 37°C, the culture was diluted with an equal volume of 2X LBmedium and germinating cells were harvested at 135, 150 or 180 minutes after addition of L-alanine [G135, G150 and G180]. | |
