Exponential phase definition
WebThe specific growth rate period is defined as the rate of increase of biomass of a cell population per unit of biomass concentration. In the sigmoid curve it occurs between the lag and stationary phases where cell growth follows a straight-line equation as follows: where Sg is the specific growth rate, Fm is the biomass (or cell density) at ...

Exponential phase definition
Did you know?
Exponential growth is a process that increases quantity over time. It occurs when the instantaneous rate of change (that is, the derivative) of a quantity with respect to time is proportional to the quantity itself. Described as a function, a quantity undergoing exponential growth is an exponential function of time, that is, the variable representing time is the exponent (in contrast to other types of gr… WebThis phase of the reaction usually occurs between cycles 0 and 15 and is known as the stationary baseline phase. The exponential phase, cycles 16-25, generally occurs once the PCR product begins to amplify, with the amount of product doubling at each cycle. Amplification will ultimately plateau as reaction components get used up over the course ...

WebGrowth of bacterial cultures is defined as an increase in the number of bacteria in a population rather than in the size of individual cells. The growth of a bacterial population occurs in a geometric or exponential manner: with each division cycle (generation), one cell gives rise to 2 cells, then 4 cells, then 8 cells, then 16, then 32, and so forth.

WebThe cell number is plotted as the log of the cell number, since it is an exponential function. Regardless of the generation time, in a growing culture the plot of the log of cell number versus time gives a characteristic curve. This curve typically has four distinct phases: lag phase, exponential (log) phase, stationary phase, and death phase. indian premier league 2010WebExponential phase.
