Problem
You are a physician trying to isolate bacterial colonies from the human gut in attempt to diagnose a gastrointestinal infection. You streak your sample on a growth media containing glucose, amino acids, and salts that contain both sulfur and phosphorous with a pH of 7. You incubate the plates in aerobic conditions at 37 oC for three days, at which point you can see clear bacterial colonies forming on the plate.
Would you feel confident in stating that you had successfully cultured all the bacteria from your gut sample? Explain why or why not?
