Oxidase and Catalase Test

Escherichia coli: gram-negative bacteria 

                         : absence of oxidase enzyme and the presence of catalase enzyme

Bacillus subtilis: gram-positive bacteria

                        : presence of oxidase enzyme and catalase enzyme 

Pseudomonas fluorescens: gram-negative bacteria. 

                                           : presence of both oxidase and catalase enzymes 

	oxidase	catalase	Gram strain
1	+	+	No mucus, +
2	+	+	Mucus, -
3	-	+	Mucus -

According to the above description, 1, 2, and 3 are Bacillus subtilis, Pseudomonas fluorescens, and Escherichia coli, respectively.
