Notes:
Summary The colony formation of soil bacteria was studied in relation to incubation time. The process was simulated by a colony-forming curve (CFC) which was a superposition of several component curves (cCFC) given theoretically by the first-order reaction (FOR) model. This model had been previously proposed to define the colony formation of cells of a single culture. Soil bacteria were divided into several groups by these cCFC, as different types of bacteria produced their own colonies. Bacteria belonging to a single group grew at a similar rate on the plating medium and each group was characterized by a different growth rate. Most copiotrophic bacteria were fast growers and most oligotrophic bacteria slow growers.
