Despite the potential relevance of … Bacterial colony morphology can reflect different physiological stages such as virulence or biofilm formation. In this work we used transposon mutagenesis to identify genes that alter colony morphology and cause differential Congo Red (CR) and Brilliant Blue G (BBG) binding in Shewanella algae, a marine indigenous bacterium and occasional human pathogen. Bacterial Colony Morphology and Identification of Bacteria. A bacterial colony consists of numerous bacterial cells derived from one parent. Colonies of different types can look different. See photos.

the characteristics of a bacterial colony are due largely in part to the genetics and physiology of the organism forming a colony. Form. refers to the overall shape of the colony. ex: circular and concentric colonies both form circular colonies, but concentric colonies appear to have rings. Spindle colonies are longer in one direction than they are wide, irregular colonies are not circular or oval, punctiform colonies are very small, filamentous and rhizoid colonies both Age- is the time the medium was inoculated with the bacterium.
