WebNov 19, 2024 · Stationary phase: The stationary phase is the period of bacterial growth when there is no longer a net rise in the population. The population expansion of microorganisms eventually stops during this phase due to a closed system, and the growth curve becomes horizontal. WebHowever, their rapid growth and efficient metabolism ultimately results in depletion of growth-supporting substrates and the population of cells enters a phase defined as the stationary phase of growth. In this phase, their reproductive ability is gradually lost. french livres currency
