Question
Following statement/statements mention the superiority
of agar w.r.t. gelatin as a solidifying agent a. Agar  d oes not melt at room temperature b. agar melts at 75deg;C c. agar is not usually decomposed by microorganism d. none of the above which of the following statement is/are correct?Solution
Agar and gelatin both are solidifying agent but agar is much better then gelatin because it does not melt at room temperature as well as is not easily decomposed by microbes. Agar melts at 85 degree Celsius whereas gelatin melts at 35-40 degree Celsius. Agar is not eaten by microbes growing on it but gelatin is eaten by microbes growing on it.
