This is a laboratory procedure used to differentiate staphylococci (catalase positive) from streptococci(catalase negative).

A catalase is a common enzyme found in nearly all living organisms exposed to oxygen.
It catalyzes the decomposition of water and oxygen.
It is important in protecting the cell from oxidative damage.

Procedure;

1.transfer a small amount of bacteria colony into a surface of clean, dry glass slide using a loop.

2.place a drop of 3% hydrogen peroxide on the slide and mix.

3.A positive result is the rapid evolution of oxygen(within 5-10sec) as evidenced by bubbling.

4.A negative result no bubbles.
