Question

Fill in the blank 1- When grown on urea agar, , the control organism used on lab #9, turned the medium pink due to the accumulation of ammonia. 2- To detect the presence of oxidase, an enzyme needed for aerobic respiration, an artificial acceptor is used that changes purple if positive. 3- To detect the presence of phenylalanine deaminase, drops of should be added to the tube, resulting in a green precipitate. 4- The control organism for the lipase test was . A halo was observed around it indicating the breakdown of olive oil in the medium. 5- If an organism is positive for the mixed acid test, it is most likely negative for the test. 6- In the nitrate reduction test, the control organism, , is able to reduce nitrates into nitrites. 7- The medium used to detect the presence of proteases was 8- The medium used to detect the presence of amylase was 9- The medium used to detect the presence of lipases was 10- To detect the presence of catalase, drops of should be added to a slide containing the organism in question and the presence of oxygen bubbles should be detected if the enzyme is presence.
