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”. Colony morphology is a way scientists can identify bacteria. There are a few basic characteristics of colony morphology that are typically evaluated. 1. Form Examination of the form and structure of bacterial colonies is termed colony morphology and is one of the first steps in characterizing and identifying a bacterial culture.
Grow an E. coli quality control strain for 18-24 hours on a MacConkey agar at 35-37°C with ~5% CO2 (or in a candle-jar). Observe the MacConkey for specific colony morphology. 2021-04-10 · Colony Morphology Characteristics of a colony such as shape, edge, elevation, color and texture. 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.

Although it's quite possible you are familiar with the states that made up the original 13 colonies, there may be some things you don't know. Here are some more interesting facts to note.

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.
It divides at a logarithmic pace until a colony appears on the plate. One colony typically equals about 1,000 bacterial cells.
