Yup, lots of bubbles (meaning it's catalase positive).

Does micrococcus roseus have beneficial properties?
Yes it does. These species of microbes secretes substances that react on the surface of your skin and harms Gram (-) bacteria. These guys are the good bugs of your skin, but they can become opportunistic and cause some nasty lesion on your skin.
What is catalase?
Catalase is a tetramer of four polypeptide chains, each over 500 amino acids long.[3] It contains four porphyrin heme (iron) groups which allow the enzyme to react with the hydrogen peroxide. The optimum pH for catalase is approximately neutral (pH 7.0),[4] while the optimum temperature varies by species.[5]
Why when adding catalase to sucrose not makes it bubble?
Catalase is an enzyme that is substrate-specific, meaning that it has a particular reaction that it will catalyze (to speed up a reaction). Hydrogen peroxide (H2O2) is the specific substrate reactant with which catalase will react (in a degradation reaction). This is the degradation (breaking down of) reaction. 2H2O2 yields 2H2O+O2 O2 is oxygen which is indicated by the rising of bubbles upon reaction between the hydrogen peroxide and the catalase. Sucrose is not the specific substrate assigned to the catalase enzyme, therefore they will not react together in a degradation reaction, hence the lack of oxygen release (lack of bubbles). I hope this was helpful to you. God bless and Jesus loves you.
What is the true relationship between pH and enzyme action?
The enzyme has an optimal point of pH at which the enzyme works best. For example a catalase enzyme works best in a pH of 7. When the pH changes it denatures the enzyme causing it to not be able to react with the substrate.
What are the limitations of the food tests?
because the indicator used will only react with certain substances, as such the sudan IV test, sudan IV only soluble in lipid, not water...

Why does fresh liver react better in H2O2 then boiled liver?
It all has to do with catalase. Catalase is an enzyme and a biological catalyst in the decomposition of H2O2. When its fresh, catalase is still present in the liver. However, when the liver is boiled, the catalase enzyme is denatured (as it is a protein).

How does sodium chloride react with Benedicts?
The Benedict reagent is not for sodium chloride testing.
What does animal testing mean?
animal testing is when scientists use animals to find out how they react with different chemicals. They would be injected into the animal and then they woul see what the animal would do and record what happened.
How else would you know if a product is safe without animal testing?
If an animal didn't react to whatever people were testing it on negatively, it doesn't mean it won't effect humans negatively.
How do heavy metals react on plants?
~I am still in the middle of testing this but heavy metal seems to stunt plants growth.~
What are the for reasons for testing cosmetics on animals?
To see if the chemicals will react harmfully with other ingredients, makeups, soaps, etc.
Why does macerated liver react faster than whole liver on hydrogen peroxide?
By macerating the liver, you are increasing its surface area (SA) therefore, the enzyme catalase can break down the hydrogen peroxide at a much faster and easier rate.
How does a girl show that she is testing you?
She will constantly question you and be repetitive with things as well as offer or present things that normally are not thought to be accepted to see how you react. If someone is testing you it is wrong and distrustful - just childish games.
What does bio chemist do do they make fire works?
No, a biochemist works with biological chemicals. i.e testing how medicines will react with the human body
