<u> Bacterial growth curve-</u>

The phase in the bacterial growth curve which is defined by  zero net growth due to a lack of nutrients and excessive waste products being present is the death phase of the growth curve.

<u>Phases of the bacterial growth curve-</u>

The bacterial growth curve is a curve that depicts the number of viable live cells in a bacterial culture over a span of time. This growth curve has four very distinct phases, which are- lag phase, log phase, stationary phase, death phase.

  • Lag phase- The first phase which is the period of metabolic growth rather than division of cells.
  • Log phase- The second phase where the cells are dividing and increasing in numbers.
  • Stationary phase- The third phase where the bacterial cells reach a stagnant period and stop dividing due to the lack of nutrients.
  • Death phase- The last phase where there is no metabolic growth or cellular division. The culture is filled with metabolic wastes from the lysis of cells.
