| 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]. |

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].
