Uses
Microbiology: Agar (CAS NO.9002-18-0) is widely used to provide a solid surface containing medium for the growth of bacteria and fungi. Agar is typically sold commercially as a powder that can be mixed with water and prepared similarly to gelatin before use as a growth medium.
Motility assays: As a gel, an agarose medium can be used to measure microorganism motility and mobility because it is porous.
Agar is also used as an impression material in dentistry and used to make salt bridges for use in electrochemistry. In formicariums, Agar can be used as a transparent substitute for sand and a source of nutrition.
