Kinetics of microcolony formation of a soil oligotrophic bacterium, Agromonas sp.

Abstract

The kinetics of budding/dividing of parent cells at different culture ages, spread on a fresh medium, was formulated by the following model N t = N ∞ [1 − exp{ − λ ( t − t r}] where N t is the number of budding/dividing cells in the parent population at time t, N ∞ is the expected number of budding/dividing cells at infinite time, λ is the rate of budding/dividing of parent cells, and t r is the retardation time. The rate of budding/dividing λ decreased with the increase in the culture age of the parent cell population.
