Colony morphology of 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). In microbiology, colonial morphology refers to the visual appearance of bacterial or fungal colonies on an agar plate.Examining colonial morphology is the first step in the identification of an unknown microbe. Some colonies may be colored, some are circular in shape, while others are irregular.

It can be used to help to identify them. Colony morphology. A swab from a bin spread directly onto nutrient agar. Colony morphology of bacteria: Introduction, types and special features of bacteria Introduction of Colony morphology Colony morphology of bacteria is a most common diagnostic methods in bacteriology for isolation and identification of bacteria on the basis of phenotypic characteristics on solid medium for the color, shape, surfaces, size, elevation, edges, opacity and consistency. Because colony morphology may be influenced by the conditions under which the species is cultured, it is important to describe those conditions accurately. Include the medium (e.g., R2A agar, Tryptic soy agar), temperature of incubation, age of the culture.

Describing Bacterial Colony Morphology Although bacterial colonies can differ in the details of their appearance, a colony basically looks like a dot growing on the medium. This dot is composed of millions of bacteria that arose through binary fission from one initial bacterium, the parent.

2016-03-01 · During the course of colony formation, a single bacterium divides to create a colony composed of billions of its descendants organized in a remarkable ordered structure. These massive cell divisions are associated with secretion of various molecules, comprising the extracellular matrix, essential for establishing a proper colony structure ( Ben-Jacob and Levine, 2006 , Branda et al., 2005 • Bacteria are prokaryotic microorganisms that do not contain chlorophyll. • They occur in water, soil, air, food, and all natural environment.

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.
