WebThe key concept of exponential growth is that the population growth rate —the number of organisms added in each generation—increases as the population gets larger. And the results can be dramatic: after 1 1 day ( 24 24 cycles of division), our bacterial population would have grown from 1000 1000 to over 16 16 billion! WebApr 9, 2024 · In a closed growth system, a bacterial population usually exhibits a predictable pattern of growth - its growth curve - that follows several stages or phases. During the lag phase growth is relatively flat and the population appears either not to be growing or growing quite slowly as newly inoculated cells are adapt to their new environment. WebJun 24, 2024 · Therefore, the Bacterial growth curve consists of 4 different phases such as the lag phase, the exponential or logarithmic phase, stationary phase, and death or decline phase.
