The end products of tryptophan degradation are indole and pyruvicacid. Why do we test for the presence of indole rather than pyruvicacid as the indicator of tryptophanase activity?
Besides the final product, what other important difference is there between the fermentation pathways of E. coli? Or, in other words, for what purpose does the cell activate the fermentative pathways when there is lack of oxygen?
