Micrococcus kristinae versus micrococcus luteus?
The easiest way to differentiate them is by color. Both are pigment producing, and while M. luteus has yellow colonies, M. roseus has pink colonies. If you need a more scientifically valid way of differentiating them, try using a nitrate reduction test. M. luteus can not reduce nitrate while M. roseus can.
Biochemical tests to confirm micrococcus luteus?
I had a bacterial unknown of M. luteus in my microbiology lab. M. luteus is a Gram positive cocci (as seen by a gram stain). A good definitive test for Gram + cocci is the catalase test. M. luteus is catalase positive. Then a nitrate test can be performed to determine that M. luteus is nitrate negative. Those alone should be enough to confirm M. luteus.
Why is micrococcus luteus negative for oxidase?
You probably got a false negative. M. luteus should be oxidase +. To determine M. luteus do a MSA plate which should not produce acid and barley grow. That means the plate will look red with a streak of yellow colonies due to the fact that M. luteus produces a yellow pigment.
Do bacteria form endospores to survive unfavorable conditions in their surrounddings?
Yes, they form Terminal, elliptical endospores.
What happens to bacteria when nutrients are scarce?
c. form endospores

Is Micrococcus luteus acid fast negative?
Micrococcus leteus is negative to VP test.

Does m luteus produce a positive or negative dnase test?
yes
Do bacteria form endospores to survive unfavorable conditions in their surrounddings?
Yes, they form Terminal, elliptical endospores.
When does endospores form?
When it wants to reproduce.
When does bacteria form Endospores?
When it wants to reproduce.
When do endospores form?
When conditions outside the bacteria get very extreme and hard to live in, the bacteria can produce endospores, these endospores store the bacteria's genetic code so the bacteria can replenish itself should it happen to die in the harsh conditions.
What is M. luteus?
Micrococcus luteus (M. luteus), is a Gram-positive bacteria that is most commonly found in mucous membranes such as the nasal cavities, the upper respiratory tract, and the lining of the mouth.Although once regarded as non-pathogenic, it is now considered an opportunistic pathogen which means that if it has a chance to cause an infection, it will.M. luteus of historical interest for the part it played in Fleming’s discovery of lysozyme. This bacterium, which is often used for educational studies, produces bright yellow colonies on nutrient agar.
When endospore form?
Endospores form during a period called binary fission.
When was Conus luteus created?
Conus luteus was created in 1833.
