Escherichia coli O157:H7 is a foodborne pathogen and can cause serious illness in humans by producing toxins that can severely damage the lining of intestines and kidneys. What are the oxygen requirements of coli? What result would you observe in the MTM agar deep test? Explain. Research on the growth requirements of this bacterium is required.

xplain the four stages of the growth curve for a microorganism. What is the generation time? Which aspect of the growth curve is used to calculate the generation time and why? How is the generation time calculated and why does it make sense that E.coli and M.tuberculosis have such drastically different generation times?
The data below were obtained for the growth of a pure culture of Escherichia coli in nutrient broth at a temperature of 37°C. Determine (1) the specific growth rate and (2) generation time of E. coli and the duration of the (3) lag and (4) log (or exponential) phases.
