Question

Quizplus · Accepted Answer

Agar is the most common solidifying agent used in microbiological media because it is not degraded by most microorganisms and doesn't melt at typical incubation temperatures. Gelatin, on the other hand, is enzymatically degraded by some microorganisms and can liquefy at higher temperatures. Alginate, silica, and polyacrylamide are less commonly used as solidifying agents in microbiological media.
