8: Bacterial Colony Morphology - Biology LibreTexts
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.
Colony Morphology of Bacteria - Microbe Online
2024年1月6日 · Colony morphology can sometimes be useful in bacterial identification. Colonies are described based on size, shape, texture, elevation, pigmentation, and effect on growth medium. Find common criteria that are used to characterize bacterial growth; It includes the form, elevation, and margin of the bacterial colony.
Colonial morphology - Wikipedia
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.
Colony Morphology – its shapes and appearance - Microbial Notes
2023年2月10日 · Colonies of bacteria usually have a shiny, smooth look. Other surface adjectives include veined, rough, wrinkled (or shriveled), dull (the reverse of gleaming), and shining. Dry, wrinkly colonies are produced by Bacillus species. Additionally, Pseudomonas stutzeri produces colonies that look wrinkled and similar. A colony’s color (pigmentation)
Colony Morphology of Various Bacteria - Laboratoryinfo.com
2022年3月7日 · There are various types of bacteria and each type produces differently looking colonies. They vary in color, share, pigmentation, and other characteristics. Colony morphology is a way of identifying bacteria. By observing the colony …
1.7: Colony Morphology - Biology LibreTexts
2024年3月14日 · On agar plates, bacteria grow in collections of cells called colonies. Each colony arises from a single bacterium or a few bacteria (CFU). Although individual cells are too small to be viewed with the unaided eye, masses of cells can be observed. Colonies can have different forms, margins, elevations and colors.
Colony Morphology of Bacteria - Biology Reader
In a colony, all the bacterial cells originate from a single mother cell and look identical to each other. By looking into the colony morphology, we can interpret the identity of bacteria. Different bacteria produce different colonies depending upon shape, size, margin and other features.

Differentiate between colony morphology and cell morphology, and describe the colony morphology of bacteria grown on a solid surface; Prepare a bacterial smear for staining; Perform a simple stain, and explain why they are useful; Visualize individual bacterial cells using oil immersion microscopy and describe their cell morphology
Identifying Bacterial Colonies: Shapes, Elevations, Textures, and …
2024年8月5日 · Learn how to identify bacterial colonies by examining their shapes, elevations, textures, and other key characteristics. Microbiologists and laboratory technicians often rely on the morphological characteristics of bacterial colonies to identify …
The Microbe: The Basics of Structure, Morphology, and Physiology …
Classical microbiology uses both gross and microscopic morphology to identify microbes. Gross morphology includes colony shape, size, and surface features (Fig. 2.1). For example, Bacillus atropheu s strain globigii produces an orange-pigmented colony on tryptic soy agar but produces small white colonies on other media.
