0.1 % agar reduces the diffusion of oxygen into medium and delays dispersion of reducing compounds and carbon dioxide, allowing growth of anaerobes.
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.
This bacterium is likely a denitrifying bacterium. Denitrifying bacteria are able to use nitrate as a terminal electron acceptor in the absence of oxygen, converting it to nitrogen gas through denitrification.
silver ions will be reducted by sugar to silver metal in high temp autoclave process.
Using a semisolid nitrate medium with a small amount of agar allows microaerophiles, which require reduced oxygen levels, to grow without being exposed to high oxygen concentrations due to the agar's ability to create an oxygen gradient. This setup mimics the low-oxygen environments that microaerophiles thrive in and aids in their growth and identification.
A concentration of 0.5-0.7% agar is typically used in semisolid medium for motility. This is lower than the typical 1.5-2% agar concentration used in solid medium, allowing motile bacteria to move more easily through the softer semisolid medium.
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.

It provides a fluid medium that the cell requires to function.

Frequency is a function of the energy level of the photon. Changing the medium does not change that energy level.

explain briefly why mosains were a good artistic medium for conveying a spiritual message.
This bacterium is likely a denitrifying bacterium. Denitrifying bacteria are able to use nitrate as a terminal electron acceptor in the absence of oxygen, converting it to nitrogen gas through denitrification.
It removes trapped oxygen from the medium
One complete scene image. I think it's short for the medium used (cellulose acetate or cellulose nitrate).
