From the graph A will have that Escherichia coli without supplement to density and likely conditions constant over Klebsiella oxytoca. When put supplemented with 0.5% yeast extract Escherichia coli and Klebsiella oxytoca density is increasing rapidly. Over time, the 10 hour Escherichia coli will have increased density, while the Klebsiella oxytoca density is reduced and a relatively stable state. When put supplemented with 0.5% yeast extract,thiamine and micronutrients. Escherichia coli and Klebsiella oxytoca are increasing rapidly, but over time, about 24 hours Escherichia coli will gradually decrease and increase over time to 48 hours, the Klebsiella oxytoca is located in steady-state over time of approximately 38 hours.
