   Type and morphology. E. coli is a gram-negative, facultative anaerobe, nonsporulating coliform bacterium. Cells are typically rod-shaped, and are about 2.0 μm long and 0.25–1.0 μm in diameter, with a cell volume of 0.6–0.7 μm 3.

   Is E coli a Gram negative bacterium?

   • E. coli is a gram-negative, facultative anaerobe, nonsporulating coliform bacterium. Cells are typically rod-shaped, and are about 2.0 μm long and 0.25–1.0 μm in diameter, with a cell volume of 0.6–0.7 μm 3. E. coli stains gram-negative because its cell wall is composed of a thin peptidoglycan layer and an outer membrane.

   How are cocci arranged?

   • Cocci bacteria can be arranged either singly, in pairs, in groups of four, in chains, in clusters or cubes consisting of eight cells. These cells remain attached during cell division. This group includes bacteria that are present as a single cell. This arrangement results when two bacterial cells occur as a pair (joined together).

   Why do E coli cells express different phenotypes?

   • So even though all of the E. coli cells present in a culture may be genetically identical, they can express different phenotypes due to the stochastic nature of gene expression. An example of such behavior is presented in the PhET gene expression basics applet 300.

   Why is Escherichia coli called Bacillus coli communis?

   • When initially isolated, Escherichia coli was designated Bacillus coli communis, a latinization describing its prominent characteristic as a “common colon bacterium” that could be readily cultured in a variety of substrates.

   The answers illustrate general principles of the interaction networks controlling gene expression. In E. coli, like many bacteria, multiple genes are organized into what are known as operons. In an operon, a single regulatory region controls the expression of multiple genes.
