WebFigure 4: Growth curves of E. coli JM109 obtained from corrected OD values. The OD600 was measured on all instruments every 30 minutes for 9.5 hours. The OD600 data was corrected by the dilution factor used for OD measurement. Samples were diluted so they were within the linear range of the optical system. The corrected OD for each Webuse of growth curves correlating OD 600 values against plate counts for any particular cell type. For reproducible results, always use the same photometer for repetitive OD 600 experiments. When using the same photometer, some factors still influence each measurement and have to be considered when the results of the turbidity measurement …
