This Demonstration displays linear and semi-logarithmic plots of the rise of a hypothetical microbial population's number,
N(time)
, in a food at constant temperature. You can modify the growth curve by slider-controlled settings of five parameters of a conventional generalized logistic model of which the original Verhulst equation is a special case.
