I would think an aerobic organism would do the worst in an oxygen poor media, which would be one of the results of having an older media sitting around.
E.coli is a facultative anaerobe.
Facultative anaerobe
Facultative anaerobes can survive without oxygen but will use oxygen if it is present.
On the basis of oxygen requirement microorganisms are classified asAerobes: organisms that use molecular oxygen as electron acceptor.Anaerobes: organisms that use some molecule other than molecular oxygen as electron acceptor.Facultative organisms : organisms that can use either molecular oxygen or some other chemical compound as electron acceptor.
A faculatative anerobe does NOT require oxygen for growth but may use if available so it can grow in aerobic and anaerobic conditions. Too much oxygen is NOT toxic. A micro-aerofile CAN'T grow without oxygen but too much oxygen is toxic so it must have a low concentration in order to grow.
Facultative anaerobes does not need o2 to grow but can also grow with o2. Obligate anaerobe cannot grow at all in the presence of o2.
yes it si a fucaltative anaerobe..check microbiology textbook as a reference

Members of the genus Serratia are facultative anaerobes. Answer from a professor of microbiology.
ecoli is mainly facultative anaerobe ,but some species is aerobes.
facultative anaerobe
Facultative anaerobes can survive without oxygen but will use oxygen if it is present.
aerotolerant anaerobes are organisms that make use of CO2 for their survival but can tolerate the presence of O2
A facultative anaerobe is an organism that makes ATP by aerobic respiration if oxygen is present. It is capable of switching to fermentation or anaerobic respiration if oxygen is present.
means that they perform fermentation only under anerobic conditions
