WebThe intercept between initial microbial biomass and the tangent to the growth curve at the time where growth rate reaches a maximum is generally referred to as the lag phase. Following the so-called exponential phase, growth rate decreases steadily towards zero reaching a stationary phase, resulting overall in a sigmoidal shape [ 12 ]. WebLag Phase.
