Suppose a liquid culture of E. coli achieves a certain turbidity that then stops increasing. However, the addition of glucose to the tube subsequently causes the turbidity to increase. Which interpretation is false? Prior to the addition of glucose, the cells had run out of a carbon source. The initial culture medium contained glucose as a carbon source. E. coli can use glucose as a carbon source. Prior to the addition of glucose, the culture still had a source of sulfur that could support growth of E. coli. None of the above.
