SUMMARY: In cultures from single cells of grown under anaerobic conditions there are variations in rate of growth of the individual colonies as measured by their diameter after a short incubation. When small and large colonies are selected the populations derived from them inherit the tendency to produce correspondingly smaller or larger colonies than the mean of those produced by the parent strain. When the growth conditions are altered then the selected character will be lost.
