cells beneath optimal growth circumstances can multiply Each and every twenty min. This might signify that immediately after eight h the population would arrive at a million cells and just after forty three h, the volume of cells created can be comparable to the amount of planet earth! The moment nutrients start to deplete, the exponential growth is slowed down as well as amounts of cells in the overall populace remains stable; This is actually the third period known as the stationary period.

The 2nd phase, essentially the most impressive, will be the exponential section during which nutrients within the medium are metabolised speedily bringing about a rapid doubling in the populace of bacterial cells. The populace of Escherichia coli
