Deletion of csdA leads to a reduced growth at low temperature. wt and ΔcsdA strains transformed with either pBR322 or a derivative bearing the csdA gene (pBD1) were grown on tetracycline-LB plates at 37°C for 15 h or at 22°C for 2 days (at 22°C, the ΔcsdA/pBR322 colonies only become visible after longer incubation times).
