It will be useful to learn the terminology used for describing common colony types. The following features of colony morphology were recorded: colony size (measured in mm by ruler), color (red, purple, or pink), translucency (opaque or translucent), degree of color (pale, bright, or dark), wetness (wet or dry), colony circumference (smooth or irregular), surface texture of center of colony, presence of roughness in outer half of colony, and overall surface shape (convex 2020-05-24 · Colony morphology is a method that scientists use to describe the characteristics of an individual colony of bacteria growing on agar in a Petri dish.

These are the characteristics used to accurately and consistently describe the morphology of a bacterial colony: Size ; Shape ; Color (also known as pigmentation) Texture z The morphological study of bacteria requires the use of microscope like. optical or light microscope, phase control microscope, dark/field microscope, electron microscope. z Staining techniques This video describing the cultural characteristics and colony morphology of Bacterial colonies on Agar plate Hope this will help you people to interpret the This exercise will help you identify the cultural characteristics of a bacterium on an agar plate---called colony morphology. Although one might not necessarily see the importance of colonial morphology at first, it really can be important when identifying the bacterium. Features of the colonies may help to pinpoint the identity of the bacterium. Colony morphology is a way scientists can identify bacteria.

Some colonies may be colored, some are circular in shape, while others are irregular.

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. 2020-03-11 2013-08-14 of bacteria produce different-looking colonies, some colonies may be colored, some colonies are circular in shape, and others are irregular.

Although one might not necessarily see the importance of colonial morphology at first, it really can be important when identifying the bacterium.

Question 12 12 2020-08-12 2007-02-01 2020-05-24 Colony morphology can sometimes be useful in bacterial identification. Colonies are described on the basis of size, shape, texture, elevation, pigmentation, and effect on growth medium. In this blog post, you will find common criteria that are used to characterize the bacterial growth. See variations in colonial morphology among various species of bacteria.
