A) We have learned about sugar fermentation before so what byproduct is produced that can be visualized by a simple color change and Why is it possible to see the color change Butanediol is another kind of fermentation and there is an important test called the test which is (+) for only a few species. How are the byproducts in this test visualized B) Hydrolytic reactions are likewise important so a few of these which help to separate groups are Tryptophan hydrolysis, Urea hydrolysis, Starch hydrolysis. The enzymes produced by specific organisms are responsible for the substrate breakdown and so these (+) results help to differentiate them from other bacteria. What enzymes break down Tryptophan, Urea and Starch Please describe how the tests are done, mention the end products and how these are visualized by color changes C) What is an API E test strip, how many tests are on this strip and which kinds of Gr(-) bacteria is it mainly used to ID? Answer these questions and write a paragraph to describe how these strips are inoculated and the results interpreted or scored to obtain the identification codes specific to organisms
