Specific growth rate (μ; hr-1) of engineered strains. The growth rate of E. coli K-12 (MG1655) and W strains harbouring exogenous DNA integrated into various different loci was measured on LB medium in the absence of selection to allow comparison with wild type strains. Bars are means; errors are standard deviations (n = 3). No significant differences were identified for either strain (1-way ANOVA; p>0.05).
