ZhangXiang d’AmalricQuentin JournetLaure CascalesEric 2013 <p>(A) Survival to exposure to osmotic stress. Viable bacteria (relative to the initial input) of the indicated strain counted after exposure for 60 min. to 0.6 M Sucrose. (B) Survival to cell envelope stress. Highest 10-fold serial dilution for which colonies are observable on LB plates supplemented with 1% sodium deoxycholate after 24 hours of incubation at 28°C. <i>p</i>-values obtained using paired Student’s <i>t-</i>test analyses are indicated (NS [non significant], <i>p</i>>0.05; ***, <i>p</i>≤0.0001).</p>
