FIG. 3.
Cell viability of P. putida strains after induction of the expression of killing genes. Cells of P. putida CMC4 (PA1-04/03::gef) (A) and CMC12 (PA1-04/03::gene E) (B) growing exponentially in M9 minimal medium with glucose and 3-methylbenzoate were transferred at time zero to medium containing glucose and either 3-methylbenzoate (closed symbols) or IPTG (open symbols). At the indicated times, viable cells were counted on LB medium plates containing 3-methylbenzoate and the appropriate antibiotics.
