Is e coli an archaebacteria or a eubacteria?
E. Coli is a eubacteria. Archaebateria is what you would normally find in extreme places such as undersea volcano vents, extremely acidic waters, and very salty seas (in the olden times, they were known to cause spoilage since eubacteria cannot survive these conditions). Eubacteria are the most abundant and the most common.
