Effects of abiotic stresses on growth of E. coli strains.
A: Growth of the E. coli control strain carrying only the pMG1 vector (1) and the transformant strain expressing IrrE (2) in LB medium after exposure to various abiotic stresses; B: Growth of the control strain (squares) and the IrrE-expressing strain (triangles) in M9 minimal medium; C: Growth of the control strain and the IrrE-expressing strain in M9 minimal medium containing 0.65 M NaCl.
