A) Considering the source of the sample, and possible variety of microbes within, describe the multiple steps (methodologies) you would take to isolate pure individual bacterial colonies for further testing/evaluation [4pts] B) Describe the key growth conditions you would have to consider when trying to cultivate these bacteria. Additionally, name one factor it would be difficult to alter and test in a standard micro lab. [5pts total] C) With the bacteria isolated from A, and with your knowledge from this week, briefly describe two simple techniques to help you categorize what type of bacteria you have isolated [3pts]
