WitrynaWhen plotting a graph for logistic population growth, an S-shaped curve will be produced. This is because the growth of the population gradually slows and levels off upon reaching carrying capacity. This is in contrast to exponential population growth, which produces a J-shaped curve , since the growth continues unchecked (Fig. 2). Witryna19 wrz 2024 · The bacterial growth curve represents the number of live cells in a bacterial population over a period of time. There are four distinct phases of the growth curve: lag, exponential (log), stationary, and death. The initial phase is the lag phase where bacteria are metabolically active but not dividing.

WitrynaIf the resulting plot is approximately linear, then a logistic model is reasonable. The same graphical test tells us how to estimate the parameters: Fit a line of the form y = mx + b to the plotted points. The slope m of the line must be -r/K and the vertical intercept b must be r. Take r to be b and K to be -r/m.
