E. coli

Escherichia coli (Abbr. E. coli) is a Gram-negative, rod-shaped bacterium, which is facultatively anaerobic. This acid-producing bacterium is commonly found in the lower intestine of warm-blooded organisms (humans and animals). E. coli is consequently an indicator bacterium for faecal contamination. Exposure to UVC causes lethal damage to E. coli.
