Coordinate with your partners to try to isolate colonies that look different from each other. Your goal is for each student to end up with 2 pure cultures of DIFFERENT genera of bacteria from as many groups as possible.<BR><BR> | Coordinate with your partners to try to isolate colonies that look different from each other. Your goal is for each student to end up with 2 pure cultures of DIFFERENT genera of bacteria from as many groups as possible. If you are interested in one of the organisms that produces an exoenzyme you might choose one of these colonies at this time. You will need to isolation streak at least 3-4 times to make sure you have a pure culture of any new organisms selected today.<BR><BR> | ||
Once you believe you have pure isolates, continue to subculture to fresh NA plates each week. | Once you believe you have pure isolates, continue to subculture to fresh NA plates each week. | ||
