Description |
Gelatin Nutrient is used, essentially, to identify pure cultures that have no specific nutritional requirements. On the other hand, gelatin liquefaction is considered very important to differentiate enteric bacilli on the basis of their proteolysis. Gelatin was one of the first solidifying agents employed in bacteriology, and helped in the development of the Plate Count Technique, performed by Koch. Nonetheless, nowadays it is not used in that way, since it was replaced by Agar, which bears incubations at higher temperatures and was not so attacked or degraded as gelatin. However, the Plate Count Method is still used with gelatin. Standard Methods still recommend it for aerobic counting at 20-22°C. |
