8 Bacterial Colony Morphology Biology Libretexts Bacteria grow on solid media as colonies. a colony is defined as a visible mass of microorganisms originating from a single mother cell. key features of these bacterial colonies serve as important criteria for their identification. characteristics of bacterial colonies. colony morphology can sometimes be useful in bacterial identification. To study the colony morphology of different bacteria, we can expose the nutrient agar plate to varying environments like air, water and soil, etc. after overnight incubation, the growth of bacterial colonies in or on the nutrient agar plate occurs. first, look for the separate bacterial colonies and label them as 1, 2, 3 and so on. The "bump" on an umbonate colony is called an umbo. 4. margin. erose is synonymous with serrated. 5. surface. surface can be smooth, glistening, rough, wrinkled, dry, powdery, moist, mucoid (forming large moist sticky colonies, brittle, viscous (difficult to remove from loop), butyrous (buttery). 6. The size of the colony can be a useful characteristic for. identification. the diameter of a representative colony. may be measured. tiny colonies are referred to as = " punctiform." surface. frequently shiny and smooth. other surface descriptions: veined.

Certain colony phenotypes, such as cocultured microbial interactions, need to be observed on a magnified scale to discern subtle changes in colony texture, color, and colony morphology. these subtle changes, when captured in detail, can be indicative of various biological phenomena, such as antibiotic resistance, microbial communications, and evolution within a microcolony ( 6 ). If the average colony or viral plaque contains 10 5 –10 9 individuals and the average spontaneous mutation rate is 10 −9 to 10 −10 per base per generation of bacteria (viruses are somewhat higher, 10 −4 to 10 −8 [24, 25]), each colony or plaque will contain at least 3,000 individuals that are genetically different from the starting organism (table 2.1).
