Expert Solution
Step 1
Gelatin is a protein which is derived from the collagen . Collagen is connective tissues. Gelatin is produced when collagen is boiled in water. The hydrolysis of gelatin detects the presence of enzyme gelatinases.
Gelatinases are proteases that are secreted extracellularly by some bacteria which hydrolyze or digest gelatin.
The production of gelatinases is used as a presumptive test for the identification of various organisms, including Staphylococcus sp., Enterobacteriaceae, and some gram-positive bacilli.
