Discussion 1. Metabolic tests look for the presence of a specific metabolic pathway or enzyme found in bacteria. How might this information be useful in the development of new antibacterial drugs? 2. How can you tell if the enzyme being tested for on a plate is an exoenzyme instead of an endoenzyme? Why is gelatin not used as a solidifying agent in microbiological media? 3. Newer tests like PCR can identify an unknown bacterium by looking for specific DNA sequences....

A Gram stain of unknown bacterium A grown for 24 hours show purple cells. Is bacterium A Gram positive or Gram negative? A gram stain of bacterium A grown for 72 hours shows both purple and pink stained cells. Additional analysis shows that bacterium A is NOT contaminated. Explain these results. You are given 2 nutrient broth tubes each containing a pure culture of one of two Gram positive bacteria. Unfortunately, the labels have washed off and you are asked...
