    Hi,

    I'm currently using the exponential growth rate constant to calculate the generation time of bacteria in a population. However, for growth that isn't exponential I'm getting answers of less than 1, and this isn't very useful if I'm trying to work out the the generation time. Is there anything I can use to calculate generation time if growth isn't exponential?

    It's the same thing as generation time.

    I thought you should always get exponential growth at some point in bacterial growth... Maybe I'm wrong..

    The formula that you can use is:

    Nt = N0 x 2^(t/td)

    Where Nt = number of cells after 't' hours
    N0 = original cell number in population
    t= time in hours
    td = doubling time
    also t/td is the number of generations

    But what are the numbers your using. Also if logs are taken this would convert this exonential to a linear graph, so check that iswell. But yh i would also assume that there should be an exponential growth of bacteria, as there growth is hardly ever stable and always changing, but check your numbers maybe you can figure a solution out.
