Minimum inhibitory concentration (MIC), maximum growth rate (μmax) and β-lactamase activity of acceptor, donor and transconjugant cells.

a Average maximum growth rate of three transconjugants randomly chosen from three different transfer experiments. All individual transconjugants were grown in two replicates.b Specific activity is reported in nanomoles of nitrocefin hydrolyzed per minute per milligram of protein. The results are presented as the means and standard deviations of two independent measurements.c β-lactamase activity was averaged from transconjugants obtained in two individual experimentsMinimum inhibitory concentration (MIC), maximum growth rate (μmax) and β-lactamase activity of acceptor, donor and transconjugant cells.
