Yes, it is catalase positive. This is because it is capable of breaking down hydrogen peroxide (H2O2) to give water and oxygen. The presence of bubbles when hydrogen peroxide is added to E. coli on a microscope slide is a phenotypic (observable physical characteristic) proof that it is catalase positive.

What two groups of bacteria can be differentiated with the catalase test?
The morphologically similar Enterococcus (catalase negative) and Staphylococcus (catalase positive) can be differentiated using the catalase test.
What enzyme distinguishes staphylococci from streptococci?
Catalase. Staphylococci are catalase positive. Streptococci are catalase negative.
Is Neisseria meningitidis Gram-positive cocci?
Neisseria gonorrhoeae ( nīsə′rēə ′gänə′rē′ī ) ( microbiology ) A gram-negativecoccus pathogen that causes the sexually transmitted disease gonorrhea
Which bacilli are gram positive oxidase negative and catalase positive?
Streptobacillus is a gram negative, oxidase negative, catalase negative, non motile organism, and 0.3-0.7 µm by 1-5 µm in lengthEscherichia coliMost of the Enterobacteriaceae are Catalase Positive. E. coli is Catalase Positive and Oxidase Negative. Do not report the previous as an answer. For gram negative, catalase negative and oxidase negative rods, it is likely that you have bacteria of the Bacteroides genus.
Does micrococcus roseus react to catalase testing?
Yup, lots of bubbles (meaning it's catalase positive).
Reaction of Bacillus Megaterium in a catalase test?
Most Bacillus species are Catalase positive.
What two groups of bacteria can be differentiated with the catalase test?
The morphologically similar Enterococcus (catalase negative) and Staphylococcus (catalase positive) can be differentiated using the catalase test.
Is bacillus subtilis catalase positive or negative?
Bacillus subtilis is catalase positive, meaning it produces the enzyme catalase which can break down hydrogen peroxide into water and oxygen.
What enzyme distinguishes staphylococci from streptococci?
Catalase. Staphylococci are catalase positive. Streptococci are catalase negative.
Why salmonella typhi is catalase positive?
it should test + for catalase but Salmonella isolates are moderate catalase reactors.
Is Neisseria meningitidis Gram-positive cocci?
Neisseria gonorrhoeae ( nīsə′rēə ′gänə′rē′ī ) ( microbiology ) A gram-negativecoccus pathogen that causes the sexually transmitted disease gonorrhea
