When recording colony morphology, it is important to also record color, optical properties (translucence, sheen) and texture (moist, mucoid or dry). of bacteria produce different-looking colonies, some colonies may be colored, some colonies are circular in shape, and others are irregular. A colony’s characteristics (shape, size, pigmentation, etc.) are termed the colony morphology. Colony morphology is the way scientists identify bacteria.

Among these, bacterial colony morphology plays a key role in the preliminary identification of the bacteria. A bacterial colony is formed by a single bacterial cell that divides by binary fission to form thousands of clones. This is the reason we call each bacterium a single colony forming unit (CFU).
