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.
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.
microaerophiles grow below the medium surface of culture, in presence of oxygen required (equal or matched ) by them .
By a simple observation; also a semisolid substance can flow without any stress.

Agar is a semi solid medium used to grow bacteria.

Because it does not inhibit bacteria form "swimming" through the medium.
By a simple observation; also a semisolid substance can flow without any stress.
Semisolid drugs are often used for topical application. These drugs are soft and pliable. Semisolid drugs include creams, ointments, most plasters, and dry-powder aerosols. I am not sure about gels?
Petroleum jelly is a semisolid mixture of hydrocarbons obtained from petroleum. I do not know what Peteroluem jelly is, maybe a semisolid mixture of Peters??

Agar is added in a concentration of 1.5% to solidify liquid media. Although there are different concentrations of agar used to create different conditions such as in Sabouraud's Agar and semisolid agar.
Semisolid media contains a 1.5% concentration of agar, which is used to grow and select isolated colonies. Semisolid media contains agar at a lower concentration (around 0.4%,) which is used for motility studies.
