Problem
1. You are a technician working in a microbiology lab. You grow two bacteria cultures, Bug A and Bug B, for two purposes: You want to harvest lactic acid for sports drinks from Bug A. You want to harvest antibiotics from Bug B for the pharmaceutical industry. Describe how you would maintain the two cultures, how you might manage their nutrient supply and waste products in order to induce them to produce the desired products. Which stage of the growth curve would you try to keep them in?
2. You are a bacterium which entered the skin through a small cut. Which innate immune defenses might come after you. If you escape the innate defenses, how might the adaptive immune system get you?
