Suppose a nutrient broth tube was inoculated with nothing but a lapful of phage, and it became cloudy after several hours of incubation. What might be a possible explanation?
Adi S.
You inoculated one phenol red broth (containing fructose) with E. coli. After incubating at 25°C for 48 hours, you get the following result (right). What can you conclude about this organism based on these results? Be sure to explain how you are able to come to your conclusion. An uninoculated control tube (left) is provided as a comparison.

You streaked an EMB plate with an unknown bacterium and saw a green metallic sheen. Since both E. coli and Citrobacter freundii provide this result - how would the SIM test help you confirm which bacterium you have?
