8: Bacterial Colony Morphology - Biology LibreTexts
网页Describe features of colonies. See variations in colonial morphology among various species of bacteria. 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.
Colony Morphology of Bacteria - Microbe Online
网页2024年1月6日 · Characteristics of bacterial colonies. 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;
Colony Morphology of Bacteria - Biology Reader
网页There are seven basic characteristics to identify bacterial colony morphology. We can describe the morphology of a bacterial colony by looking into the aspects like: Shape; Elevation; Margin; Size; Colour; Opacity; Texture; The above features can be grouped into two categories (form and appearance) that are as follows: Forms of Bacterial Colonies
Identifying Bacterial Colonies: Shapes, Elevations, Textures, and …
网页2024年8月5日 · The morphology of bacterial colonies is a fundamental aspect of microbiological studies, providing initial clues about the identity of the microorganism. One of the most noticeable features is the shape of the colony, which can vary significantly among different bacterial species.
The Microbe: The Basics of Structure, Morphology, and Physiology …
网页2011年11月19日 · 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 atropheus strain globigii produces an orange-pigmented colony on tryptic soy agar but produces small white colonies on …
1.7: Colony Morphology - Biology LibreTexts
网页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.
4: Colony and Cell Morphology; Simple Stains - Biology LibreTexts
网页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

Understanding Evolving Bacterial Colonies | SpringerLink
网页Microbial colonies are collections of cells of the same organism (in contrast to biofilms, which comprise multiple species). Within an evolving colony, cells communicate, pass information to their daughters, and assume roles that depend on their spatiotemporal distribution.
