You inoculate two test tubes with the same amount of identical growth medium and with the same number of identical yeast cells and grow these cells under identical conditions except for the presence or absence of oxygen. a) After 12 hours, all of the glucose in each culture has been consumed. You determine the number of total cells found in each culture and find that one culture has more cells than the other. Which culture would have the greater cell density, the one grown aerobically or the one grown anaerobically? Explain why the culture you chose above can make more cells with the same amount of glucose than the other culture.

The culture you are working has a doubling time of 2 hours and a cell density of 3 x 106 cells per mL. For your experiment, you first dilute the culture 100 fold. Assuming that there is no lab phase and that the cells remain in exponential growth the entire time, what is the cell density (cells/mL) after 10 hours?

Suppose you have a bacterium, which is normally killed in an hour when growing in a medium containing penicillin. This bacterium is an auxotroph and requires tryptophan for growth. When placed in a medium lacking both tryptophan and penicillin, the bacterium neither grows nor dies for several hours. Question: Is it killed in an hour in a medium lacking tryptophan but containing penicillin? (Yes/No and explain briefly why).
