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.

Shape – Escherichia coliis a straight, rod shape (bacillus) bacterium. Size – The size of Escherichia coliis about 1–3 µm × 0.4–0.7 µm (micrometer). Arrangement Of Cells – Escherichia coliis arranged singly or in pairs. Motility – Escherichia coli is a motile bacterium. Some strains of E. coliare non-motile.

⇒ Special requirements – Escherichia coli or E. coli have no complex nutritional requirements and readily grow in an ordinary media like Nutrient Agar medium (NAM). Commonly the NAM & MacConkey Agar medium is used for the cultivation of Escherichia coli in the Laboratory. ⇒Optimum temperature – Escherichia coliranges from 10–40°C but the optimum te...
In liquid culture media like Trypticase soy broth or Nutrient broth, the growth of the bacterium occurs as a turbidity in the broth medium with a heavy deposits that disperses in the medium on shaking, which is further analyzed for the morphology (under the microscope), gram reaction, biochemical tests, and Escherichia colispecific tests. In Blood ...

Aug 10, 2022 · Arrangement of Cocci. Cocci bacteria can exist singly, in pairs (as diplococci ), in groups of four (as tetrads ), in chains (as streptococci ), in clusters (as stapylococci ), or in cubes consisting of eight cells (as sarcinae). Cocci may be oval, elongated, or flattened on one side. Cocci may remain attached after cell division.
