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 [2pts] Name one factor it would be difficult to test in a standard micro lab. [1pt] [3pts total] C) With the bacteria isolated from A, briefly describe two simple techniques to help you categorize what type of bacteria you have isolated [4pts] D) You are informed that the pond from where this sample has been taken, is in a region where the temperatures can vary greatly. Describe an experimental approach to ‘most accurately’ determine the organism’s optimal temperature for growth, and how using the data, might be able to classify that microbe as being a Psychrophile, Mesophile, Thermophile, or Hyperthermophile.
