APPLICATION OF THE 1ST-ORDER REACTION (FOR) MODEL TO NODULATION BY BRADYRHIZOBIUM-JAPONICUM IN THE NODULATION-DILUTION FREQUENCY METHOD AND ESTIMATION OF TIME OF INITIATION OF NODULATION

Hattori (1985) proposed a model to simulate the relation between the number of bacterial colonies on agar plates and the incubation time, using the following equation where N(t) is the number of colonies observed at time t, and N∞λ, and t rare parameters expressing the expected number of colonies observed at an infinite time, the rate of increase in the number of colonies, and the time of initiation of colony formation, respectively. This model is called the first-order reaction (FOR) model because the Eq. 1 is essentially the same as that of the first-order reaction. © Taylor & Francis Group, LLC.
