Catalase Test

  1. What is catalase?
    Enzyme produced to break down toxins
  2. Does aerobes produce catalase and if they do, what is it for?
    Yes, they produce catalase to break down hydrogen peroxide
  3. How does catalse break down hydrogen peroxide?
    Convert hydrogen peroxide to water and gaseous oxygen
  4. Which type of bacteria don't have catalase?

  5. Does obligated aerobe produce catalase? Does faculative anaerobe?
    No and maybe(check the lab manual)
  6. What is the equation of the conversion of hydrogen peroxide?
    2H2O2-------------->2H2O + O2
  7. What happen when hydrogen peroxide is added to catalase positive bacteria?
    O2 buble
  8. Which bacteria type does the Catalase test differentiate?
