Catalyses and Oxidase Tests on Unknown
For this week’s lab assessment, you will answer just a few questions regarding the oxidase and
catalyses assays and unknown results (listed below) and then you will continue to work on your lab report. For week 10, you will make sure that you are:
1) What are the bubbles that you see in a positive (+) catalyses reaction?
2) Bacteria capable of synthesizing the enzyme catalase hydrolyze and gaseous oxygen.
3) The oxidase test is used to identify microorganisms containing the enzyme.
4) Cytochrome oxidase transfers electrons from the electron transport chain to (the
final electron acceptor) and reduces it to water.
