Growth curve protocol

Preparation

1. Autoclave 250 ml Erlenmeyer’s with 100 ml of LB for each measurement. If you use a magnetic stir, make sure it’s inside as well.
2. Autoclave LB for the control measurements and dilutions.
3. Heat or cool baths or stoves 4, 8, 15, 21, 25, 30 and 37oC, with the Erlenmeyer’s already in them.
4. Inoculate Top10 cells in 3 ml of LB in greinertubes and grow them overnight at 37 oC. Make sure you at least 1 ml of inoculated TOP 10 cells for each measurement.

Procedure

1. Mix all the precultures.
2. Put 1 ml off this solution in each of the sterile 250 ml Erlenmeyer’s.
3. Make sure it is properly mixed.
4. Measure start OD at 600.nm
5. Make sure all measurements remain at their respective temperatures.
6. Measure the OD at 600nm every half hour.

Note: Start diluting when your OD at 600nm measurements go above 0.500
Stop measuring when dilutions of 5x are no longer sufficient
