If you have isolated a bacterium that grows in a medium containing an organic substrate and nitrate in the absence of oxygen The nitrate is reduced to nitrogen gas This bacterium is?
Using anaerobic respiration
When testing microaerophils some microbiologists prefer to use a semisolid nitrate medium that contains a small amount of agar why is this done?
Microbiologists testing microaerophils prefer to use a semisolid nitrate medium that contains a small amount of agar to get more accurate results. This is also done to speed up the results.
When testing microaerophiles prefer to use a semisolid nitrate medium that contains small amount of agar Why?
microaerophiles grow below the medium surface of culture, in presence of oxygen required (equal or matched ) by them .
What concentration of agar is used in a semisolid medium for motility How does that compare to a typical solid medium?
Agar concentration rates for a semisolid medium for mobility typically ranges from 0.2 to 0.4 percent. Solid medium can have as much as 15 to 20 percent agar.
Why is silver nitrate added to plant tissue culture medium after autoclave?
silver ions will be reducted by sugar to silver metal in high temp autoclave process.
What is the nitrate broth?
Cultures are grown in beef extract medium containing potassium nitrate. Gases produced from nitrate reduction are captured in Durham tubes placed in the nitrate medium. Answer found in Benson's Microbiological Applications: Laboratory Manual in General Microbiology Eleventh Edition by Alfred E. Brown on page 258.

Why frequency of light is not change When it enter from a rarer medium to denser medium?
Frequency is a function of the energy level of the photon. Changing the medium does not change that energy level.
