Ex. 5-4 Catalase 1) In the Catalase test (5-4), if bacteria was added to hydrogen peroxide on the slide, it might produce a false result. 2) Explain why adding bacteria to the hydrogen peroxide on a slide rather than adding the hydrogen peroxide to the bacteria on the slide might give a false result? 3) Would the false result be a false positive or would the false result be a false negative?
