The morphology and some other biological properties of colony-like communities are described. Colony-like communities are formed after the growth of large numbers of bacteria simultaneously plated onto the limited area of agar. The morphology of colony-like communities of bacteria of different genera and species is similar and differs from that of colonies of these microbes. The number of colony-forming units reaches a maximal value at 24 h and does not depend on the number of bacteria in inocula.
