Question;- Write the modes of action for the following measurements. There may be more than one measurement for each mode and/or more than one mode for each measurement. ■ Radioactive methionine incorporation ■ Radioactive uracil incorporation ■ Radioactive thymine incorporation ■ Glucose depletion ■ DNA present in the broth

Complete and correct. Explain the results.

Batch culture time prediction: A strain of Escherichia coli has been genetically modified to produce human protein. A batch culture is started by inoculating 12 g of cells into a 100 liters bubble column fermenter containing 10 g/l glucose. The culture does not exhibit a phase lag. The maximum specific growth rate of the cells is 0.9 h^-1, the glucose biomass yield is 0.575 g/g. Estimate the time required to reach the stationary phase.

Growth Problem.A culture with approximately 1x104 cells/mL were incubated. After 7 hours, the number of cells had increased to 5x108. a) How long was the generation time in minutes?b) How many generations have occurred?

Need help.

True or false. Based on the above results none of the above cultures showed motility.  View attached photo.

None
