1. Growth curve
The growth curve is a graphical representation of the increase in a microbial population over time under controlled conditions. It typically follows a characteristic **sigmoid (S-shaped) pattern** and consists of four distinct phases: lag, log (exponential), stationary, and death. During the lag phase, cells adapt to the new environment; in the log phase, rapid cell division occurs; the stationary phase shows a balance between growth and death due to nutrient depletion; and in the death phase, the number of viable cells declines. The growth curve helps in understanding microbial behavior, optimizing culture conditions, and determining the best phase for experimental and industrial applications.
