Webx ( t) = c t + x 0. Similarly, we can write the proportional growth model like this: Δ x Δ t = α x. And as a differential equation like this: d x d t = α x. If we multiply both sides by d t and divide by x, we get. 1 x d x = α d t. Now we integrate both sides, yielding: ln x = α t + K. WebThe growth of a bacterial population occurs in a geometric or exponential manner: with each division cycle (generation), one cell gives rise to 2 cells, then 4 cells, then 8 cells, then 16, then 32, and so forth. The time required for the formation of a generation, the generation time (G), can be calculated from the following formula:
