colonies of soil bacteria There are typically 40 million bacterial cells in a gram of soil and a million bacterial cells in a millilitre of fresh water; in all, there are approximately five nonillion (5×10 30 ) bacteria on Earth, forming a biomass on Earth, which exceeds that of all plants and animals .

Dec 15, 2020 When bacterial colonies form on an agar plate, their distinct characteristics (also known as colony morphology) are an indication of what type of

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 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. colonies of soil bacteria There are typically 40 million bacterial cells in a gram of soil and a million bacterial cells in a millilitre of fresh water; in all, there are approximately five nonillion (5×10 30 ) bacteria on Earth, forming a biomass on Earth, which exceeds that of all plants and animals . Among these, bacterial colony morphology plays a key role in the preliminary identification of the bacteria. A bacterial colony is formed by a single bacterial cell that divides by binary fission to form thousands of clones.

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. In the identification of bacteria and fungi much weight is placed on how the organism grows in or on media.

Examining colonial morphology is the first step in the identification of an unknown microbe. The term “colony morphology” refers to the visible characteristics of a colony. 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 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. Common colony characteristics of bacteria Because colony morphology may be influenced by the conditions under which the species is cultured, it is important to describe those conditions accurately.
