coli. The selected temperature is normally a compromise in between sensitivity and specificity as not all strains of E. coli will expand, or grow and produce gas, at these better incubation temperatures.
Not enough sound area for colony morphology: TSB is really a liquid medium, which suggests it doesn't supply a good floor for observing colony morphology or undertaking selected tests that require sound agar.
You could possibly use a strong electrode. You'll find electrodes for measurement in semisolid samples such as meat, cheese and fruit.
