Colonies that differ in appearance are typically different bacterial strains, species, or genera. However, colony morphology is not a reliable way to identify bacteria, as many different types of bacteria have similar colony morphology. Colony morphology of bacteria on the basis of following features: Size Shape Elevation Margin or edge color Surface appearance Density Consistency Haemolysis Odor Pigmentation BACTERIAL COLONY MORPHOLOGY Bacteria grow on solid media as colonies. A colony is defined as a visible mass of microorganisms all originating from a single mother cell, therefore a colony constitutes a clone of bacteria all genetically alike. In the identification of bacteria and fungi much weight is placed on how the organism grows in or on media. Some colonies may be colored, some are circular in shape, while others are irregular. The characteristics of a colony (shape, size, color, etc.) are termed the “colony morphology”.

A bacterial colony consists of numerous bacterial cells derived from one parent. Colonies of different types can look different. See photos. · More like this.

colonies of soil bacteria There are typically 40 million bacterial cells in a gram of soil and a million bacterial cells in a millilitre of fresh water; in all, there are approximately five nonillion (5×10 30 ) bacteria on Earth, forming a biomass on Earth, which exceeds that of all plants and animals . 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).

2015-06-01 · The Colony Morphology Ontology (CMO) is the first controlled vocabulary addressing the specificities of the morphology of clinically significant bacteria, whereas the MorphoCol publicly Web-accessible knowledgebase is an end-user means to search and compare CMO annotated colony morphotypes.

Furthermore, alterations in colony traits may reflect The morphology of a colony results from characteristics of the individual bacteria viewed collectively. For example, Streptococcus pneumoniae colonies are smooth in appearance if the bacteria have a protective glycocalyx capsule and the colonies appear rough appearing in strains that do not have capsules.
