Answer:
<h2>Reduced ability to colonize the mammalian gut.</h2>
Explanation:
The Entner-Doudoroff Pathway (ED Pathway) is a metabolic pathway that is most notably in Gram-negative bacteria, some + bacteria and archaea. Glucose is the starting molecuke in the ED pathway and through a series of enzyme assisted chemical reactions it is catabolized into pyruvate.
Those mutants of E. coli lacking a key enzyme in Entner-Doudoroff  (ED Pathway)Pathway leads to reduced ability to colonize the mammalian gut.
