What is the test that separates enterococcus faecalis and lactococcus lactis?
To diagnose Enterococcus faecalis: (Facultative anaerobic) First, do the Gram stain: Gram positive cocci in chains catalase test: negative PYR disc: positive
Reaction of Bacillus Megaterium in a catalase test?
Most Bacillus species are Catalase positive.
What is the confirmation biochemical test for clostridium?
catalase
What is the result of catalase test for streptomyces?
positive
What indicates a test for catalase production is positive?
sugar
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.

Why salmonella typhi is catalase positive?
it should test + for catalase but Salmonella isolates are moderate catalase reactors.
Reaction of Bacillus Megaterium in a catalase test?
Most Bacillus species are Catalase positive.
Catalase test useful for differentiation of staph?
The main criterion for differentiation between Staphylococcus and Streptococcus genera is the catalase test. Staphylococci are catalase positive whereas Streptococci are Catalase negative. Catalase is an enzyme used by bacteria to induce the reaction of reduction of hydrogen peroxide into water and oxygen.
What is catalase test?
Catalse Test Catalase (also known as peroxidase) is an enzyme that catalyses the breakdown of hydrogen peroxide to oxygen and water. Most higher organisms produce catalase, but in bacteriology this test is usually used to differentiate staphylococci (Catalase positive) from streptococci (Catalase negative). Chemical equation for the breakdown of hydrogen peroxide:2H2O2 → 2H2O + O2 In this test a drop of hydrogen peroxide is emulsified with the bacterial growth, if the organism is catalase positive active bubbling is seen (formation of oxygen) In catalase negative reactions no active bubbling is seen
What is the confirmation biochemical test for clostridium?
catalase
What is the result of catalase test for streptomyces?
positive
What are the reagents used in the catalase test?
hydrogen peroxide
What indicates a test for catalase production is positive?
sugar
Why is it avisable to perform test of unknown catalase positive organism along with the organism you are testing?
you need to test both the experiment-organism and an organism which you already know is catalase-positive, in the same environment in order to compare the results and determine if your experiment-organism is catalase-positive. - See more at: http://www.chacha.com/question/why-is-it-advisable-to-perform-a-catalase-test-on-a-known-catalase%26%2345%3Bpositive-organism-along-with-the-organism-you-are-testing#sthash.oChX8ZqW.dpuf
What tests would separate micrococcaceae from the streptococcaceae?
Catalase test
