Expose various concentrations of the bacteria, in different concentrations of phenol and at different time intervals, starting from 0hr (point of inoculation), going through Lag phase, and then to Log phase, and Stationary phase. The parameters are for you to decide. After the each time interval take a fixed amount of the culture sample and proceed with Miles and Misra's method where one is able to count the numbers of viable bacteria. The numbers of viable bacteria obtained at different time intervals will indicate the generation time. Samples for Miles and Misra's counts must at least be in duplicate.
