WebDuring the exponential (or logarathmic) growth phase, a bacterial culture mimics a first-order chemical reaction, i.e. the rate of increase of cells is proportional to the number of bacteria present at that time. The constant of proportionality, µ, is an index of the growth rate and is called the growth rate constant: WebThe exponential growth of E. coli bacteria can be modeled using the formula: N = N0 * e^(rt) Where N is the population at time t, N0 is the initial population, e is the mathematical constant
WebExponential growth models are often used for real-world situations like interest earned on an investment, human or animal population, bacterial culture growth, etc. The general exponential growth model is y = C ( 1 + r ) t , where C is the initial amount or number, r is the growth rate (for example, a 2 % growth rate means r = 0.02 ), and t is ...
