Catalase Oxidase Test

Catalase Oxidase Test. Bacterial identification (catalase test) Positive catalase reaction The catalase test is one of the three main tests used by microbiologists to identify species of bacteria If the bacteria possess catalase (ie are catalasepositive) when a small amount of bacterial isolate is added to hydrogen peroxide bubbles of oxygen are observed The catalase test is done by placing a.
