One of the significant adaptions occurred in one strain of E. coli. In general, this bacteria is known for not being able to use citrate in an aerobic environment as an energy source, even though it could use citrate under anaerobic conditions because it already has the machinery to process citrate.
E. coli, or Escherichia coli, is a type of bacterium that is naturally present in the intestines of humans and animals where it does not usually cause any problems. However, there are certain types (or strains) of Escherichia coli that can cause poisoning.Escherichia coli O157:H7 (or E. coli O157:H7) is one such strain, and it has been responsible for several E. coli outbreaks in the US, Canada, Spain, France, Germany, Japan and the UK since 1982.owever, there are certain types (or strains) of Escherichia coli that can cause poisoning.
