What is Ecoli physical characteristics?

Answer 1

Escherichia coli (E. coli) is a rod-shaped, Gram-negative bacterium typically measuring about 1 to 2 micrometers in length and 0.5 micrometers in diameter. It has a smooth cell surface and is characterized by its flagella, which allow for motility. E. coli is generally non-sporulating and possesses a polysaccharide capsule in some strains, contributing to its virulence. Under a microscope, it appears as a pale pink color when stained with Gram stain due to its thin peptidoglycan layer.
