I think, srteptococcus is Aerotolerant organism, because it doesn't use oxygen for metabolism, but are able to grow in oxygen. Even they are able to grow with oxygen the amount of oxygen required is less than normally exists in air.

Is staphylococcus epidermidis positive for nitrogen reduction?

yes. it is a weak positive for this test though. Better idea for identification would be to run some fermentation tests, like mannitol, sucrose, trehalose and mannose. after you have done some type of growth on salt agar and tested its susceptibility to novobiocin and perhaps lysostaphin.


Is Staphylococcus aureus positive for catalase?

Yes, Staphylococcus aureus is positive for catalase because it produces the enzyme catalase, which helps to break down hydrogen peroxide into water and oxygen. This results in the production of bubbles when hydrogen peroxide is added to a colony of Staphylococcus aureus.


What substance in muscle stores oxygen temporarily?

Myoglobin is synthesized in muscle cells and imparts the reddish-brown color of skeletal muscle tissue. Like hemoglobin, myoglobin can combine loosely with oxygen. This ability to temporarily store oxygen reduces a muscle's requirement for a continuous blood supply during muscular contraction.


Is staphylococcus aureus methyl red positive?

Staphylococcus aureus is typically methyl red negative. Methyl red test is used to determine the ability of an organism to perform mixed-acid fermentation of glucose, with a positive result indicating a significant drop in pH. Staphylococcus aureus is not known to produce enough acid to yield a positive result with the methyl red test.

Is S epidermidis an endospore?

No, Staphylococcus epidermidis is not an endospore-forming bacteria. Endospores are a survival mechanism produced by certain bacterial species, such as Bacillus and Clostridium, but not by Staphylococcus epidermidis.


What is smaller in size Staphylococcus epidermidis or E. coli?

Staphylococcus epidermidis is generally smaller in size compared to E. coli. Staphylococcus epidermidis typically measures about 0.5 to 1.0 micrometers in diameter, while E. coli is usually around 1.0 to 3.0 micrometers in length and 0.5 micrometers in diameter. Thus, Staphylococcus epidermidis is considered to be smaller overall.


What organism is the largest staphylococcus epidermidis bacillus subtilis or escherichia coli?

Bacillus subtilis is the largest among the three organisms mentioned - Staphylococcus epidermidis, Bacillus subtilis, and Escherichia coli. Bacillus subtilis is a rod-shaped bacterium that is larger in size compared to the spherical Staphylococcus epidermidis and Escherichia coli.

Is staphylococcus epidermidis citrate positive?

No, Staphylococcus epidermidis is typically citrate negative, meaning it cannot utilize citrate as a carbon source for growth. This characteristic can be used in biochemical tests to help differentiate it from other bacteria.


Can staphylococcus epidermidis reduce nitrate?

no it cannot, it is nitrate reduction negative


Does staphylococcus epidermidis have true motility of brownian motion?

Staphylococcus epidermidis does not have true motility like flagella-driven movement, but it can exhibit Brownian motion due to random thermal energy causing cells to move passively. This movement is not directional or controlled by the bacteria, unlike true motility.


What enzyme is not found in S epidermidis but is found in S aureus?

Coagulase is an enzyme that is found in Staphylococcus aureus but not in Staphylococcus epidermidis. It helps S. aureus to form blood clots and evade the host immune response.

What is colony morphology of S epidermidis?

Staphylococcus epidermidis typically forms small, white or cream-colored colonies with a circular shape on agar plates. They are generally smooth and opaque in appearance.
