Escherichia coli (/ ˌ ɛ ʃ ɪ ˈ r ɪ k i ə ˈ k oʊ l aɪ /; also known as E. coli) is a Gram-negative, facultatively anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms (endotherms). read more

The E. coli genome encodes a variety of distinct dehydrogenase and terminal reductase enzymes that accomplish anaerobic respiration. Their synthesis usually requires the absence of O 2 (anaerobiosis) and the presence of the respective enzyme substrate. read more

To determine which of the two anaerobic electron acceptors used by E. coli in the intestine provides the superior colonization advantage, we competed E. coli EDL933 narG narZ with E. coli EDL933 frdA and E. coli MG1655 narG narZ with E. coli MG1655 frdA (Fig. 3). read more
