Thread: Longest lived empires/states in history. 1 out of 1 members found this post helpful. Many lists have been written about the most long-lived empires or states in the history of mankind and oddly enough nobody seems to agree on the ranking.
E. coli is a Gram-negative (bacteria which do not retain crystal violet dye), facultative anaerobic (that makes ATP by aerobic respiration if oxygen is present, but is capable of switching to fermentation or anaerobic respiration if oxygen is absent) and nonsporulating bacterium.
Species: Escherichia coli is one of five species recognized under the Genus Escherichia. What makes E. coli unique is by these biochemical activities: ferments lactose, possesses lysine decarboxylase, is Vogus-Proskauer negative, produces indole, doesn't grow on nitrate, and doesn't produce H2S.amily: Escherichia coli fits into the family Enterobacteriaceae because members of this group are motile via peritrichous flagella that grows well at 37oC, is Oxidase negative, Catalase positive, and reduces nitrates.
