If an organism is able to convert the sodium citrate in simmons citrate agar to pyruvate what are some possible reasons why an organism might ferment rather than metabolize it oxidatively in the Krebs?

Citrate, a Krebs cycle (i.e., TCA cycle or citric acid cycle) intermediate, is generated by many bacteria; however, utilization of exogenous citrate requires the presence of citrate transport proteins (permeases). Upon uptake by the cell, citrate is cleaved by citrate lyase to oxaloacetate and acetate. The oxaloacetate is then metabolized to pyruvate and CO2.

What is simmons citrate agar?

Simmons citrate agar is a differential agar used to determine if a sample bacteria can utilize citrate as its only carbon source. The agar is initially a green color due to the bromo thymol blue pH indicator in it. If a bacteria uses the citrate, the by-products are ammonia and ammonium hydroxide both of which will alkalize the agar and increase the pH to the point of changing the indicator's color to blue, so the whole agar turns from green to blue.


Home come E.coli can't grow on Simmons Citrate Media?
