+Agar is made from the cell walls of some algae species , mainly from East Asia.
+In microbiology, microbial growth media are almost invariably solidified with agar instead of the gelatin used until the end of the 19th century. Agar is more resistant to gelatin than the high temperature used in sterilization, and gelatin gels become liquid at higher incubation temperatures. Agar gel becomes liquid at 95 ° C and is more stable at higher temperatures than gelatin gels; it solidifies at 45 ° C. Thus, the addition of thermolabile substances before solidification is possible. Because some microorganisms can digest gelatin, this is another reason.
