Bacterial Growth Curve Results

  • This is a continuation of the growth curve experiments from 5 June 2009
  • Data was entered into Excel, and the average OD as well as elapsed time computed.
  • Scatter plot was plotted, and a line of best fit was added. This provided us with a way of "guesstimating" the elapsed time needed before reaching ODs of ~0.4 to 0.6.
  • Results showed that the BW27783 cells grew fastest with a slope of 0.0038 OD/min. Full results are summarized below.
Strain Slope Value (in OD/min) Equation R-sq Value
BW27783 0.0038 y = 0.0038x + 0.0531 0.984
DB3.1 0.0022 y = 0.0022x + 0.0845 0.9471
DH5a 0.0025 y = 0.0025x + 0.0782 0.96908
