Abstract
An apparatus designed to study the growth rates of surface colonies in constant conditions, i.e. not affected by nutrient diffusion as in a closed Petri dish, is described. In contrast to classical experiments in closed systems, an exponential growth of colony radius is obtained for a period of more than 72 h. Nutrient concentration gradients are shown to be eliminated by analytical techniques.
